================================================
You are a triage assistant for the Hetu-Galvatron project, an automatic distributed training system for Transformer / LLM models.
Galvatron has three core modules:
- Profiler (galvatron/core/profiler/): measures hardware bandwidth and model compute/memory
- Search Engine (galvatron/core/search_engine/): DP-based optimal parallelism strategy search
- Runtime (galvatron/core/runtime/): executes hybrid parallelism (PP, TP, DP, SP, EP, MoE)
Supported models live under galvatron/models/ (currently gpt/ and moe/).
Given an issue title and body, output ONLY a JSON object with these fields:
{
"labels": ["<label1>", ...],
"component": "<component name>",
"priority": "P0|P1|P2|P3",
"summary": "<one-sentence summary>",
"needs_info": true|false
}
Label taxonomy (choose all that apply):
- bug: Confirmed or likely bug
- enhancement: Feature request
- installation: Install / build / dependency issue
- usage: How-to question
- performance: Throughput, memory, communication issue
- model-support: New model request
- rfc: Design proposal
- documentation: Docs improvement
- good first issue: Suitable for newcomers
- needs-info: Not enough detail to act on
Component mapping:
- profile, bandwidth, nccl -> Profiler
- search, cost model, DP algorithm, strategy -> Search Engine
- pipeline, 1F1B, GPipe, PP -> Runtime/Pipeline
- tensor parallel, TP, column parallel, row parallel -> Runtime/TP
- MoE, expert, router, token dispatch -> Runtime/MoE
- FSDP, DDP, ZeRO, sharded data -> Runtime/DP
- checkpoint, save, load, HuggingFace convert -> Runtime/Checkpoint
- GPT model, sequential, hybrid parallel model -> Model/GPT
- MoE model -> Model/MoE
- YAML, config, arguments, args -> Config
Priority:
- P0: Crash, data corruption, security — blocks users completely
- P1: Significant bug or regression — workaround exists but painful
- P2: Feature request, moderate bug, performance issue
- P3: Nice-to-have, cosmetic, docs typo
Rules:
1. If the issue body is too short or missing reproduction steps, set needs_info to true and add needs-info label.
2. If the issue mentions multiple components, list all in labels but pick the primary one for component.
3. Be conservative with P0 — only use it for clear blockers.
4. Output valid JSON only, no additional text.

Rules:
1. Be factual — describe what the diff does, not what you think it should do.
2. Flag any changes to public APIs, config formats, or default values as potential breaking changes.
3. If the diff modifies galvatron/core/runtime/ without corresponding test changes, note it in test coverage.
4. Keep the summary under 300 words.
5. Do not include the diff itself in the output.
6. Output markdown only.

## Newcomer's Guide - Try Hardware and Model Profiling
In the [models](https://github.com/PKU-DAIR/Hetu-Galvatron/tree/main/galvatron/models) folder, we provide some example models and provide the profiling information of the model's computation and memory, as well as the recommended parallel strategies in the configs folder. However, it is unrealistic to measure the corresponding profiling data for all models and hardware devices, so we encourage you to measure different hardware and models and submit PRs. The specific profiling method can be referred to the [Profiling with Galvatron](https://hetu-galvatron.readthedocs.io/en/latest/3_quick_start/quick_start.html#profiling-with-galvatron) section.
### How to Contribute Profiling Data
1. **Choose Hardware Platform**: Select GPU models or other hardware platforms we haven't covered yet
2. **Choose Model**: Select from existing models or add new model architectures
3. **Run Profiling**: Follow the documentation guide for computation and memory profiling
4. **Submit Data**: Submit profiling results as PR to the corresponding configs directory
5. **Verify Results**: Ensure accuracy and reproducibility of profiling data
This is a very beginner-friendly way to contribute, helping you become familiar with Galvatron's working principles while providing valuable data to the community.

Galvatron is an automatic distributed training system designed for Transformer models, including Large Language Models (LLMs). It leverages advanced automatic parallelism techniques to deliver exceptional training efficiency. This repository houses the official implementation of Galvatron-2, our latest version enriched with several new features.
## Key Features
### (1) Enhanced Efficiency via Automatic Parallelism
#### Enlarged Parallelism Search Space
Incorporate multiple popular parallelism dimensions of distributed training, including DP (Data Parallelism), SDP (Sharded Data Parallelism, support ZeRO-1, ZeRO-2 and ZeRO-3), PP (Pipeline Parallelism, support both GPipe & Pipedream-flush / 1F1B-flush), TP (Tensor Parallelism), SP (Sequence Parallelism, support Megatron-SP and Deepspeed-Ulysses). Also incorporate CKPT (Activation Checkpointing) as a special parallelism dimension.
#### Fine-grained Hybrid Parallelism
Galvatron's approach to hybrid parallelism represents a significant advancement in distributed training optimization. Rather than applying a one-size-fits-all strategy, the system enables layer-wise parallelization, allowing each transformer layer to utilize an independent combination of parallel strategies. This granular approach ensures optimal resource utilization by adapting to the specific computational and memory requirements of each layer.
The system dynamically combines multiple parallelism types, carefully considering the trade-offs between computation, memory usage, and communication overhead. This hybrid approach is particularly powerful when dealing with complex model architectures, where different layers may benefit from different parallelization strategies.
#### Efficient Automatic Parallelism Optimization
The heart of Galvatron's efficiency lies in its sophisticated optimization engine. Through careful cost modeling, the system accurately estimates computation requirements, predicts memory usage patterns, and models communication overhead for different parallelization strategies. This comprehensive modeling enables intelligent decision-making in strategy selection.
The optimization process employs advanced search algorithms with dynamic programming that consider multiple objectives simultaneously, including memory efficiency and communication costs. The system automatically adapts to hardware constraints while ensuring optimal performance.
### (2) Versatility
Galvatron's versatility extends across the entire spectrum of Transformer architectures. In the realm of language models, it excels at handling everything from traditional BERT-style encoders and GPT decoders to complex T5-style encoder-decoder models. For Large Language Models (LLMs), the system provides specialized optimizations that enable efficient training of models with trillions of parameters, carefully managing memory and computational resources.
The system's capabilities extend beyond language models to vision transformers. Galvatron maintains its efficiency while adapting to the unique requirements of each architecture. In the future, Galvatron will also support multi-modal architectures.
### (3) User-Friendly Interface
Despite its sophisticated underlying technology, Galvatron prioritizes user accessibility. Users can begin training with minimal code changes, supported by comprehensive documentation and practical examples. The system also offers seamless integration with dataloader of popular framework , alongside robust checkpoint management capabilities, making it a practical choice for both research and production environments.
## System Architecture
Galvatron's architecture consists of three tightly integrated core modules that work together to deliver efficient distributed training:
### (1) Galvatron Profiler
The Profiler serves as the foundation of the system, conducting comprehensive analysis of both hardware capabilities and model characteristics. On the hardware side, it measures inter-device communication bandwidth and computational throughput of each device. For model profiling, it analyzes computation patterns, memory requirements, and communication needs of different model components. This detailed profiling information forms the basis for intelligent strategy decisions.
### (2) Galvatron Search Engine
The Search Engine represents the brain of the system, leveraging the profiling data to discover optimal parallelization strategies. It employs sophisticated algorithms to explore the vast space of possible parallel configurations and automatically determine the most efficient combination of parallelism strategies for each layer of the model.
### (3) Galvatron Runtime Framework
The Runtime Framework implements the execution layer, translating the high-level parallelization strategies into efficient distributed operations. The framework provides a robust and flexible execution environment that adapts to different hardware configurations and model architectures.
### Integration and Workflow
These three modules work seamlessly together to simplify the distributed training process. Users only need to provide hardware environment and Transformer model configuration.
The system automatically handles all aspects of distributed training optimization, from initial profiling through strategy selection to efficient execution. This architecture ensures both ease of use and high performance, making sophisticated distributed training accessible to a broader range of users while maintaining the flexibility needed for advanced applications.
Through this modular design, Galvatron achieves a balance between automation and customization, enabling both simple deployment for standard cases and detailed control for specialized requirements.

## Quick Start
### Profiling with Galvatron
The first step to use Galvatron is to profile the hardware environment and the model computation time. Galvatron will automatically save the profiled results into config files.
(1) Firstly, to profile the hardward environment, ```cd galvatron/profile_hardware```, write the host address into ```hostfile```, set ```NUM_NODES, NUM_GPUS_PER_NODE, MPI_PATH``` in ```scripts/profile_hardware.sh``` and run:
``` shell
sh scripts/profile_hardware.sh
```
Galvatron will call [nccl-tests](https://github.com/NVIDIA/nccl-tests) to profile the communication bandwidth.

``` shell
sh scripts/profile_computation.sh
```
### Parallelism Optimizing with Galvatron
After profiling the environments, Galvatron is able to automatically optimize the parallelism strategy for the given Transformer model. Given the memory budget, Galvatron provides the fine-grained hybrid parallel strategy with maximum throughput. The optimized parallelism strategy will be saved in `galvatron/models/model_name/configs` for the training. Users can train the model with the provided optimal strategy to obtain the optimal throughput.
To conduct parallelim optimization, ```cd galvatron/models/model_name```, customize ```NUM_NODES, NUM_GPUS_PER_NODE, MEMORY``` in ```scripts/search_dist.sh```, run:
``` shell
sh scripts/search_dist.sh

# Overview
Galvatron is an automatic distributed training system designed for Transformer models, including Large Language Models (LLMs). It leverages advanced automatic parallelism techniques to deliver exceptional training efficiency. This repository houses the official implementation of Galvatron-2, our latest version enriched with several new features.
## Key Features
### (1) Enhanced Efficiency via Automatic Parallelism
#### Enlarged Parallelism Search Space
Incorporate multiple popular parallelism dimensions of distributed training, including DP (Data Parallelism), SDP (Sharded Data Parallelism, support ZeRO-1, ZeRO-2 and ZeRO-3), PP (Pipeline Parallelism, support both GPipe & Pipedream-flush / 1F1B-flush), TP (Tensor Parallelism), SP (Sequence Parallelism, support Megatron-SP and Deepspeed-Ulysses). Also incorporate CKPT (Activation Checkpointing) as a special parallelism dimension.
#### Fine-grained Hybrid Parallelism
Galvatron's approach to hybrid parallelism represents a significant advancement in distributed training optimization. Rather than applying a one-size-fits-all strategy, the system enables layer-wise parallelization, allowing each transformer layer to utilize an independent combination of parallel strategies. This granular approach ensures optimal resource utilization by adapting to the specific computational and memory requirements of each layer.
The system dynamically combines multiple parallelism types, carefully considering the trade-offs between computation, memory usage, and communication overhead. This hybrid approach is particularly powerful when dealing with complex model architectures, where different layers may benefit from different parallelization strategies.
#### Efficient Automatic Parallelism Optimization
The heart of Galvatron's efficiency lies in its sophisticated optimization engine. Through careful cost modeling, the system accurately estimates computation requirements, predicts memory usage patterns, and models communication overhead for different parallelization strategies. This comprehensive modeling enables intelligent decision-making in strategy selection.
The optimization process employs advanced search algorithms with dynamic programming that consider multiple objectives simultaneously, including memory efficiency and communication costs. The system automatically adapts to hardware constraints while ensuring optimal performance.
### (2) Versatility
Galvatron's versatility extends across the entire spectrum of Transformer architectures. In the realm of language models, it excels at handling everything from traditional BERT-style encoders and GPT decoders to complex T5-style encoder-decoder models. For Large Language Models (LLMs), the system provides specialized optimizations that enable efficient training of models with trillions of parameters, carefully managing memory and computational resources.
The system's capabilities extend beyond language models to vision transformers. Galvatron maintains its efficiency while adapting to the unique requirements of each architecture. In the future, Galvatron will also support multi-modal architectures.
### (3) User-Friendly Interface
Despite its sophisticated underlying technology, Galvatron prioritizes user accessibility. Users can begin training with minimal code changes, supported by comprehensive documentation and practical examples. The system also offers seamless integration with dataloader of popular framework , alongside robust checkpoint management capabilities, making it a practical choice for both research and production environments.
## System Architecture
Galvatron's architecture consists of three tightly integrated core modules that work together to deliver efficient distributed training:
### (1) Galvatron Profiler
The Profiler serves as the foundation of the system, conducting comprehensive analysis of both hardware capabilities and model characteristics. On the hardware side, it measures inter-device communication bandwidth and computational throughput of each device. For model profiling, it analyzes computation patterns, memory requirements, and communication needs of different model components. This detailed profiling information forms the basis for intelligent strategy decisions.
### (2) Galvatron Search Engine
The Search Engine represents the brain of the system, leveraging the profiling data to discover optimal parallelization strategies. It employs sophisticated algorithms to explore the vast space of possible parallel configurations and automatically determine the most efficient combination of parallelism strategies for each layer of the model.
### (3) Galvatron Runtime Framework
The Runtime Framework implements the execution layer, translating the high-level parallelization strategies into efficient distributed operations. The framework provides a robust and flexible execution environment that adapts to different hardware configurations and model architectures.
### Integration and Workflow
These three modules work seamlessly together to simplify the distributed training process. Users only need to provide hardware environment and Transformer model configuration.
The system automatically handles all aspects of distributed training optimization, from initial profiling through strategy selection to efficient execution. This architecture ensures both ease of use and high performance, making sophisticated distributed training accessible to a broader range of users while maintaining the flexibility needed for advanced applications.
Through this modular design, Galvatron achieves a balance between automation and customization, enabling both simple deployment for standard cases and detailed control for specialized requirements.

# Quick Start
## Profiling with Galvatron
The first step to use Galvatron is to profile the hardware environment and the model computation time. Galvatron will automatically save the profiled results into config files.
(1) Firstly, to profile the hardward environment, ```cd galvatron/profile_hardware```, write the host address into ```hostfile```, set ```NUM_NODES, NUM_GPUS_PER_NODE, MPI_PATH``` in ```scripts/profile_hardware.sh``` and run:
``` shell
sh scripts/profile_hardware.sh
```
Galvatron will call [nccl-tests](https://github.com/NVIDIA/nccl-tests) or [pytorch profiler](https://pytorch.org/tutorials/recipes/recipes/profiler_recipe.html) to profile the communication bandwidth. You can choose one of them by setting ```--backend``` to ```nccl``` or ```torch``` in ```scripts/profile_hardware.sh```.
For ```nccl``` format, users need to set the following variables:
- ```nccl_test_dir```: the directory of nccl-tests
- ```mpi_path```: the path of mpi
- ```start_mb```: the start communication bandwidth
- ```end_mb```: the end communication bandwidth
- ```scale```: the scale of communication bandwidth
- ```hostfile```: the host file, which needs to contain the IP addresses or hostnames of all nodes
Additionally, users need to set the environment variable ```NCCLTEST_OTHER_ARGS```, which is used to specify the additional environment variables for nccl-tests. For example, it can be used to specify the IB device for nccl-tests.
For ```torch``` format, users need to set the following variables:
- ```master_addr```: the address of master node
- ```master_port```: the port of master node
- ```node_rank```: the rank of current node
- ```envs```: the environment variables for torch
Additionally, users need to set the environment variable ```ENVS```, which is used to specify the environment variables for torch.
In ```torch``` format, the script will not directly profile the bandwidth, but will generate four scripts, ```profile_allreduce```, ```profile_p2p```, ```profile_allreduce_sp```, ```profile_all2all_sp```. Users need to run these scripts on all nodes one by one to get the bandwidth of different communication modes.
Note that ```master_addr```, ```master_port```, ```node_rank``` can be set in the form of ```'$xxx'``` in ```scripts/profile_hardware.sh```, so that the variable names can be reserved in the generated scripts, and then retrieves them from environment variables when running the scripts.
Galvatron provides different configuration files for different ```backend``` in the default script. Users can modify them based on the default configurations.
(2) Secondly, to profile the model computation time and memory usage, ```cd galvatron/models/model_name``` and run:
``` shell
sh scripts/profile_computation.sh
sh scripts/profile_memory.sh
```
## Parallelism Optimizing with Galvatron
After profiling the environments, Galvatron is able to automatically optimize the parallelism strategy for the given Transformer model. Given the memory budget, Galvatron provides the fine-grained hybrid parallel strategy with maximum throughput. The optimized parallelism strategy will be saved in `galvatron/models/model_name/configs` for the training. You can train the model with the provided optimal strategy to obtain the optimal throughput.
To conduct parallelim optimization, ```cd galvatron/models/model_name```, customize ```NUM_NODES, NUM_GPUS_PER_NODE, MEMORY``` in ```scripts/search_dist.sh```, run:
``` shell
sh scripts/search_dist.sh
```
The script will automatically run the search code in the background and generate the search log results in files beginning with `Search`. When you see the following marker in the file, it indicates that the search has concluded, and no other commands need to be executed before this point:
```
========================= Galvatron Search Engine End Searching =========================
```
After the search concludes, the parallel strategy obtained will be generated in the `configs` folder. The strategy is stored in JSON format, with file names starting with `galvatron_config_{model_size}_`.
See more usage details of the customized parallelism optimization in [Galvatron Model Usage](../4_galvatron_model_usage/galvatron_model_usage.html#parallelism-optimizing-with-galvatron).
## Training with Galvatron
Galvatron provides a simple way to train Transformer models in fined-grained hybrid parallelism fashion. You can either train Transformer models with the searched optimal parallel strategy by specifying argument ```galvatron_config_path``` to obtain the optimal throughput, or use any parallel strategies as they like. Galvatron support two hybrid parallel config modes, including JSON config mode and GLOBAL config mode. Ypi can specify parallel strategies by modifying only a few arguments.
To train the model with Galvatron, ```cd galvatron/models/model_name```, set ```NUM_NODES, NUM_GPUS_PER_NODE, MASTER_ADDR, MASTER_PORT, NODE_RANK```, and run:
``` shell
sh scripts/train_dist_random.sh
```
Use the `--galvatron_config_path` parameter to apply the parallel strategy obtained from the search engine. If you have the relevant datasets and checkpoints ready, you can complete the actual training by modifying and running `scripts/train_dist.sh`.
Tips: Before proceeding, ensure whether you need to use the `--set_seqlen_manually` parameter to manually specify the sequence length for the training model.
See detailed guidance and more customized training options in [Galvatron Model Usage](../4_galvatron_model_usage/galvatron_model_usage.html#training-with-galvatron).

================================================
# Galvatron Model Usage
Galvatron provides sample code for a bunch of mainstream models to demonstrate how a Transformer model should be rewritten to accommodate Galvatron's automatic optimization API. In addition, you can quickly start from these models, optimizing parallelism strategies in their own hardware environment. Enter model directory by ```cd model_name``` to start.
## Profiling with Galvatron
The first step to use Galvatron is to profile the hardware environment and the model forward computation time.
(1) Firstly, profile the hardward environment. Please refer to the [Quick Start](../3_quick_start/quick_start.html#profiling-with-galvatron) for details. Make sure that the hardward environment is already profiled before running any script in model directory!
(2) Secondly, profile the model computation time:
``` shell
sh scripts/profile_computation.sh
```
For models and configurations in the [Galvatron Model Zoo](https://github.com/PKU-DAIR/Hetu-Galvatron/blob/main/galvatron/models), the profiling step is already done. For user-customized models, an extra step is required to profile the model memory cost:
``` shell
sh scripts/profile_memory.sh
```
### Other Profile Arguments
By setting `profile_min_batch_size`, `profile_max_batch_size`, and `profile_batch_size_step`, you can control the batch sizes used during time profiling. Specifically, the time profiling will be performed using batch sizes in `range(profile_min_batch_size, profile_max_batch_size + 1, profile_batch_size_step)`. Similarly, by setting `profile_min_seq_length`, `profile_max_seq_length`, `profile_seq_length_step`, you can control the sequence lengths used during time and memory profiling. The former should be used with `profile_mode == 'batch'`, and the latter with `profile_mode == 'sequence'`. For `static` mode, you can control the batch size by setting `profile_batch_size`, and control the sequence length by setting `profile_seq_length_list`. Further details about `profile_mode` will be discussed later.
## Parallelism Optimizing with Galvatron
Given the cluster and the memory budget, Galvatron Search Engine will generate the optimal parallelism strategy automatically. The optimized parallelism strategy will be saved in `configs` as JSON file for the training. To conduct parallelim optimization with Galvatron Search Engine, run:
``` shell
sh scripts/search_dist.sh
```
You can customize multiple parallelism optimization options:
### Model Configuration
You can set `model_size` and easily get a pre-defined model configuration. You can also customize model configuration: specify `set_model_config_manually` to `1` and specify model configs manually, or specify `set_layernum_manually` to `1` and specify layer numbers manually only.
### Cluster Size & Memory Constraint
Galvatron can perform searching over multiple nodes with same number of GPUs. You should set `num_nodes`, `num_gpus_per_node` and `memory_constraint` (memory budget for each GPU).
### Batch Size & Chunk
For batch size controlling, the searching process starts from `min_bsz` and ends at `max_bsz`, with a scale of `bsz_scale`. You can also set `settle_bsz` to find the optimal strategy when batch size is `settle_bsz`. Additionally, you can configure `settle_chunk` to determine the optimal strategy for a chunk size of `settle_chunk`.
### Parallelism Search Space
Galvatron incorporates five parallelism dimensions in search space (`dp` for data parallel, `sdp` for sharded data parallel, `tp&vtp` for tensor parallel, `pp` for pipeline parallel, and `ckpt` for activation checkpointing). You can use pre-defined search space (`full` for layerwise optimization over all parallelism dimensions introduced in Galvatron, `3d` for model-wise optimization over `(dp,tp,pp)`, and other options for layerwise optimization over the corresponding combination of dimensions). You can disable any parallelism dimension by set `disable_*` to `1`.
Please refer to ```galvatron_search_args``` in [arguments.py](https://github.com/PKU-DAIR/Hetu-Galvatron/blob/main/galvatron/core/arguments.py) for the full list of searching arguments.
### Other Searching Arguments
Set `sequence-parallel` to account for the `Megatron-TP-SP` method when building the cost model.
Set `fine_grained_mode` to `0` / `1`(default:`1`) to disable/enable fine-grained parallel strategy and search. For the former, the search engine will find a global parallel strategy, meaning the same parallel strategy is applied to all layers. For the latter, it refers to the standard fine-grained parallel strategy search.
Set `profile_mode` to `static` / `batch` / `sequence` (default:`static`) to determine the estimation method for computation time and memory when building a cost model, `static` indicates that computation time increases proportionally with batch size. In contrast, `batch` suggests that computation time grows linearly with batch size. Specifically, we will use an $\alpha-\beta$ model to fit a linear function based on the profiled data. To ensure accuracy, when using `batch`, we require profile results for 8 different batch sizes for the same layer type. Additionally, `sequence` uses profiled data to model memory and time performance for other sequence lengths. In practice, `profile_mode` in the searching argument should typically match the profile argument. When using `static` or `batch` modes, user also need to ensure the sequence length is consistent. However, this is not necessary when using the `sequence` mode.
Set `sp_space` to `tp+sp` / `tp` (default:`tp`) to determine the search space for sequence parallelism. `tp+sp` represents considering both Megatron-SP and Ulysses, while `tp` represents considering only Megatron-SP.
Set `no_global_memory_buffer` to disable the estimation of global memory for all-gather buffer when using Megatron-SP. In Megatron-SP, a buffer is allocated to store the results of all-gather communication operations. This memory is not released, and as the sequence length increases, the memory usage of this buffer can become significant.
Moreover, we provide parallel searching options, which can be enabled by enable `parallel_search` and using `worker` to set the number of threads for parallel searching, default is 2xCPU cores. We also provide `log_dir` to set the path for saving the searching log.
**`sp_space` set to `tp+sp` is incompatible with `tp_consec` set to 0. The search for `tp_consec` is quite uncommon, and we plan to remove it in future versions.**
## Training with Galvatron
To train the model with Galvatron, run:
``` shell
sh scripts/train_dist.sh
```
You can customize multiple training options:
### Checkpoint loading & saving
#### Checkpoint loading
Galvatron supports loading Huggingface models and adapts to fine-grained parallelism strategies. With a simple weight conversion process, this can be achieved by executing the following command:
```shell
cd tools
bash convert_{MODEL_TYPE}_h2g.sh
```
You need to modify the script by setting INPUT_PATH and OUTPUT_PATH to the directories where the checkpoint files are stored before and after conversion, respectively.
Please note that the weight conversion is independent of the parallelism strategy.
Next, you can use the following arguments in their training script to load the checkpoint:
```shell
--initialize_on_meta 1 \
--load ${OUTPUT_PATH}
```
For checkpoints previously saved by Galvatron, you can load them by adding ```--load_distributed```. Note that this method requires the current parallel strategy to be consistent with the parallel strategy used when the checkpoint was saved.
#### Checkpoint saving
Galvatron supports saving checkpoints during training. You can use the following arguments in their training script to save the checkpoint:
```shell
--save ${OUTPUT_PATH}
--save-interval ${SAVE_INTERVAL}
```
Galvatron will store the distributed checkpoint of the specified parallel strategy in the target directory, including both parameters and optimizer state.
To convert an already saved distributed Galvatron checkpoint into the Hugging Face format, you can use the following command:
```shell
cd tools
bash convert_{MODEL_TYPE}_g2h.sh
```
### Training with datasets
Galvatron supports the use of the Megatron dataset, with preprocessing and usage methods compatible with [Megatron](https://github.com/NVIDIA/Megatron-LM).
### Model Configuration
you can set `model_size` and easily get a pre-defined model configuration. You can also customize model configuration: specify `set_model_config_manually` to `1` and specify model configs manually, specify `set_layernum_manually` to `1` and specify layer numbers manually, specify `set_seqlen_manually` to `1` and specify sequence length manually.
### Cluster Environment
Galvatron can perform training over multiple nodes with same number of GPUs. You should set ```NUM_NODES, NUM_GPUS_PER_NODE, MASTER_ADDR, MASTER_PORT, NODE_RANK``` according to the environment.
### Parallelism Strategy
In distributed training with Galvatron, you can either train models with the optimal parallelism strategy searched by the parallelism optimization to obtain the optimal throughput, or specify the hybrid parallelism strategies as they like.
#### JSON Config Mode [Recommended]
JSON config mode is a **recommended** layerwise hybrid parallel training mode, activated by assigning argument `galvatron_config_path` with the config path in `configs` directory. In JSON config mode, you don't need be aware of the details of searched parallelism strategies, and don't need to tune any parallelism strategies or hyper-parameters. You can simply use the searched optimal parallelism strategy saved in `configs` directory by setting `galvatron_config_path` as `./configs/galvatron_config_xxx.json`. For advanced you, JSON config mode also provides a more fine-grained approach to parallelism tuning.
A hybrid parallel strategy is represented in JSON format as follows:
```json
{
// Pipeline parallelism configuration
"pp_deg": <num_pipeline_stages>,
"pp_division": "<layers_per_stage_1>,<layers_per_stage_2>,...",
"pipeline_type": "pipedream_flush", // or "gpipe"
"chunks": <num_micro_batches>,
// Tensor parallelism configuration (per-layer)
"tp_sizes_enc": "<tp_size_1>,<tp_size_2>,...,<tp_size_n>",
"tp_consecutive_flags": "<consec_1>,<consec_2>,...,<consec_n>",
// Data parallelism configuration (per-layer)
"dp_types_enc": "<dp_type_1>,<dp_type_2>,...,<dp_type_n>",
"default_dp_type": "zero2", // or "ddp", "zero3"
// Sequence parallelism configuration (per-layer)
"use_sp": "<sp_flag_1>,<sp_flag_2>,...,<sp_flag_n>",
// Memory optimization configuration (per-layer)
"checkpoint": "<ckpt_flag_1>,<ckpt_flag_2>,...,<ckpt_flag_n>",
// Global training configuration
"global_bsz": <global_batch_size>,
// Vocabulary parallelism configuration
"vtp": <vocab_tp_size>,
"vsp": <vocab_sp_flag>,
"embed_sdp": <embed_sdp_flag>
}
```
The JSON configuration fields are organized by category:
### Pipeline Parallelism Configuration
- `pp_deg`: Number of pipeline stages for model segmentation
- `pp_division`: Number of layers in each pipeline stage, comma-separated
- `pipeline_type`: Scheduling strategy ("pipedream_flush" or "gpipe")
- `chunks`: Number of micro-batches for pipeline parallelism
### Tensor Parallelism Configuration
- `tp_sizes_enc`: Per-layer tensor parallelism degrees
- `tp_consecutive_flags`: GPU allocation method (1=consecutive, 0=non-consecutive)
### Data Parallelism Configuration
- `dp_types_enc`: Per-layer data parallelism type (0=default_dp_type, 1=zero3)
- `default_dp_type`: Default data parallelism strategy ("ddp", "zero2", or "zero3")
### Sequence Parallelism Configuration
- `use_sp`: Per-layer Ulysses sequence parallelism flags (0=disabled, 1=enabled)
### Memory Optimization
- `checkpoint`: Per-layer activation checkpointing flags (0=disabled, 1=enabled)
### Global Configuration
- `global_bsz`: Total training batch size across all devices
### Vocab Embedding Parallelism
- `vtp`: Tensor parallelism degree for vocab embedding
- `vsp`: Vocab embedding sequence parallelism flag (0=disabled, 1=enabled)
- `embed_sdp`: Vocab embedding data parallelism flag (0=default_dp_type, 1=zero3)
#### GLOBAL Config Mode
GLOBAL config mode is a global hybrid parallel training mode, activated by assigning argument `galvatron_config_path` as `None`. In this mode, you can specify `pp_deg`, `global_tp_deg`, `global_tp_consec`, `sdp`, `global_train_batch_size`, `chunks`, `global_checkpoint`, `pipeline_type` to determine the global parallelism strategy, and all the layers of the Transformer model uses the same hybrid parallelism strategy assigned by the you (just as in Megatron-LM).
### Arguments
1. JSON Config Mode
- `galvatron_config_path`: str, json config path, whether to activate JSON config mode. If activated, arguments in GLOBAL config mode will be ignored and overwritten by the JSON config.
2. GLOBAL Config Mode
- `global_train_batch_size`: Integer, global batch size of distributed training.
- `pp_deg`: Integer, pipeline (PP) degree,.
- `global_tp_deg`: Integer, tensor parallel (TP) degree.
- `global_tp_consec`: `0`/`1`, whether the communication group of TP is consecutive, (eg., [0,1,2,3] is consecutive while [0,2,4,6] is not).
- `sdp`: `0`/`1`, whether to use SDP instead of DP.
- `chunks`: Integer, number of microbatches of PP.
- `global_checkpoint`: `0`/`1`, whether to turn on activation checkpointing to the whole model.
- `pipeline_type`: `gpipe` or `pipedream_flush`, choose the pipeline type to use.
- `vocab_tp`: Interger, vocab embedding parallel degree.
### Other Training Optimizations
Set `mixed_precision` to allow mixed precision training, e.g., `bf16`. Set `use-flash-attn` to allow [FlashAttention-2](https://github.com/Dao-AILab/flash-attention) features.
Set `sequence-parallel` to enable `Megatron-TP-SP` method, which can further reduce memory usage.
Set `use_ulysses` to enable [Ulysses-SP](https://github.com/microsoft/DeepSpeed/blob/master/blogs/deepspeed-ulysses/README.md) method, which will replace `Megatron-TP-SP`. Once activated, the TP (tensor parallel) dimension will automatically be converted to the SP (sequence parallel) dimension.
Set `no_async_grad_reduce` to disable the asynchronous gradient synchronization method, which is enabled by default. In Galvatron, during each iteration of training, when gradient accumulation is required, the default behavior is to perform the gradient reduce scatter operation only after all backward passes are completed. This approach reduces communication overhead but incurs additional memory usage: each device holds a full copy of the gradients until gradient synchronization, causing Zero-2 to degrade to Zero-1.When `no_async_grad_reduce` is set, Galvatron synchronizes gradients after every backward step, maintaining low memory usage. However, this introduces additional communication, though much of it can overlap with computation. The trade-off is increased complexity in the cost model, potentially reducing the accuracy of cost model. We plan to offer a more fine-grained and accurate cost model in the future.
Please refer to function ```galvatron_training_args``` in [arguments.py](https://github.com/PKU-DAIR/Hetu-Galvatron/blob/main/galvatron/core/arguments.py) for the full list of training arguments.
**Ulysses is only supported on hf models.**

# Search Engine Usage
## Integration with Galvatron Runtime
The Search Engine can be used in conjunction with the Galvatron runtime as described in the [Quick Start](../3_quick_start/quick_start.html#profiling-with-galvatron).
## Standalone Usage
Beyond its integration with the Galvatron runtime, the Galvatron Search Engine can also be used independently, offering more flexible modeling and search capabilities.
Specifically, to use the Search Engine independently, you need to modify configurations related to both the environment and the model.
### Environment Configuration
Environment configurations are located in the `profile_hardware/hardware_configs` directory and include files such as `allreduce_bandwidth_{num_nodes}nodes_{num_gpus}gpus_per_node.json`, `p2p_bandwidth_{num_nodes}nodes_{num_gpus}gpus_per_node.json`, and `overlap_coefficient.json`. The first two files represent the measured total bandwidth for allreduce or p2p operations at different scales (with `num_nodes` nodes and `num_gpus` GPUs per node).
The format of these files is as follows:
`allreduce_bandwidth_{num_nodes}nodes_{num_gpus}gpus_per_node.json`:
```
{
"allreduce_size_{group_size}_consec_[0/1]": {bandwidth}
...
}
```
Here, `group_size` denotes the size of the communication group, `0/1` indicates whether the group is contiguous, and `bandwidth` represents the measured bus bandwidth.
`p2p_bandwidth_{num_nodes}nodes_{num_gpus}gpus_per_node.json`:
```
{
"pp_size_{stage_num}": {bandwidth}
...
}
```
`stage_num` signifies the size of the pp stage, and `bandwidth` indicates the bus bandwidth for p2p communication at this stage size.
`overlap_coefficient.json`:
```
{
"overlap_coe": {coe}
}
```
When computation and communication overlap, the CUDA kernel is simultaneously preempted by both, causing a slowdown. `coe` represents the slowdown ratio of the kernel when overlap occurs, typically ranging between 1.1 and 1.3.
Additionally, if you want to perform a search with `sp_space` set to `tp+sp`, you will need a new file named `sp_time_{num_nodes}nodes_{num_gpus}gpus_per_node.json`. The format of this file is as follows:
```
{
"allreduce_size_{group_size}_{message_size}MB_time": {time},
"all2all_size_{group_size}_{message_size}MB_time": {time},
...
}
```
Here, `group_size` denotes the size of the communication group for the corresponding operation (allreduce/all2all), `message_size` is the amount of data being communicated (in MB), and `time` is the duration of this communication operation.
### Model Configuration
Model configurations are found in the `models/{model_name}/configs` directory.
It is essential to modify or create files prefixed with `computation_profiling` and `memory_profiling` within `models/{model_name}/configs`. The file names follow the format `[computation/memory]_profiling_[bf16/fp16/fp32]_hidden_{hidden_size}_head_{head_num}.json`, where `bf16/fp16/fp32` indicates the data type used during training, and `hidden_size` and `head_num` correspond to the model's configuration.
The format of these files is as follows:
`computation_profiling_[bf16/fp16/fp32]_hidden_{hidden_size}_head_{head_num}.json`:
```
{
"layertype_{layer_type}_bsz{batch_size}_seq{sequence_length}": {time},
}
```
`layer_type` denotes the type of layer. For GPT models, it is 0 for decoder layers, while for T5 models, it can be 0 or 1, representing encoder and decoder layers, respectively. `time` is the forward computation time per layer for inputs with the specified `batch_size` and `sequence_length`.
`memory_profiling_[bf16/fp16/fp32]_hidden_{hidden_size}_head_{head_num}.json`:
```
{
"layertype_{layer_type}[/_sp]": {
"{sequence_length}": {
"parameter_size": {layer_parameter},
"tp_activation_per_bsz_dict": {
"checkpoint": {layer_ckpt_act},
"1": {layer_tp1_act},
"2": {layer_tp2_act},
...
}
}
...
}
"other_memory_pp_off[/_sp]": {
"{sequence_length}": {
"model_states": {
"1": {othe_pp_off_tp1_ms},
"2": {othe_pp_off_tp2_ms},
...
},
"activation": {
"1": {othe_pp_off_tp1_act},
"2": {othe_pp_off_tp2_act},
...
}
}
}
"other_memory_pp_on_first[/_sp]": {
"{sequence_length}": {
"model_states": {
"1": {othe_pp_on_first_tp1_ms},
"2": {othe_pp_on_first_tp1_ms},
...
},
"activation": {
"1": {othe_pp_on_first_tp1_act},
"2": {othe_pp_on_first_tp1_act},
...
}
}
}
"other_memory_pp_on_last[/_sp]": {
"{sequence_length}": {
"model_states": {
"1": {othe_pp_on_last_tp1_ms},
"2": {othe_pp_on_last_tp1_ms},
...
},
"activation": {
"1": {othe_pp_on_last_tp1_act},
"2": {othe_pp_on_last_tp1_act},
...
}
}
}
}
```
The meaning of layer_type is the same as in the computation_profiling file; `/_sp` indicates whether sequence parallel was enabled during measurement; `sequence_length` represents the sequence length during measurement; layer_parameter represents the memory occupied by parameters of a single layer; `layer_ckpt_act` represents the activation memory usage of a single layer when using checkpoint strategy, `layer_tpx_act` represents the activation memory of a single layer when using tensor parallel dimension x. For cases with sequence parallel enabled, `layer_tpx_act` has an inverse relationship with x, so it's not necessary to manually measure every strategy. However, when sequence parallel is not enabled, each strategy needs to be measured separately; `other_pp_[off/on_first/on_last]_tpx_[ms/act]` represents the memory size of model states or activations occupied by modules other than regular layers (mainly embedding modules) when applying tensor parallel dimension x to the embedding layer in pp=1, first stage of pp>1, and last stage of pp>1 respectively. Here, model states include optimizer states, parameters, and gradients.
### Usage
You can modify the contents of `models/{model_name}/scripts/search_dist.sh` to use Galvatron or third-party profiling data for modeling and search. For third-party data, refer to the previous sections to modify the relevant configuration documents. If you want to use Galvatron's profiling data, please refer to [Galvatron Model Usage](../4_galvatron_model_usage/galvatron_model_usage.html).
If you want to manually specify the path of the configuration file, please modify the following parameters:
- `--memory_profiling_path`: Use this parameter to specify the path to the memory profiling configuration file.
- `--time_profiling_path`: Use this parameter to specify the path to the time profiling configuration file.
- `--allreduce_bandwidth_config_path`: Use this parameter to specify the path to the allreduce bandwidth configuration file.
- `--p2p_bandwidth_config_path`: Use this parameter to specify the path to the p2p bandwidth configuration file.
- `--overlap_coe_path`: Use this parameter to specify the path to the overlap coefficient configuration file.
- `--sp_time_path`: Use this parameter to specify the path to the sequence parallelism time configuration file.
- `--output_config_path`: Use this parameter to specify the path to the output parallel strategy file.
Configuration file names follow the format described in the previous sections.

### Galvatron's Hybrid Parallel Model Construction Process
Before adding a new model, let's understand the general process Galvatron uses for constructing hybrid parallel models.
Galvatron builds models without manually defining the entire model structure. Instead, it uses corresponding model structures from [transformers](https://github.com/huggingface/transformers) or [flash attention](https://github.com/Dao-AILab/flash-attention). You can add the suffix `hf` or `fa` to `MyModel` to distinguish the backend you choose for the model structure. If you're unsure which backend to choose, we recommend `hf` as Galvatron provides more comprehensive support for it (the `fa` model does not support the Ulysses-SP parallel method). The process of constructing a hybrid parallel model is detailed in [`construct_hybrid_parallel_model_api`](https://github.com/PKU-DAIR/Hetu-Galvatron/blob/main/galvatron/core/hybrid_parallel/model.py). The specific process is as follows:
1. **Preprocessing Configuration**: Obtain information such as hybrid parallel strategy and model configuration.
2. **Communication Group Generation** (Step 0): Generate communication groups required for various parallel strategies.
3. **Build Tensor Parallel Model** (Step 1): Use model-specific TP functions (defined in `MyModelModel_tensor_parallel.py`) to build a tensor parallel model.
4. **Build Sequential Model** (Step 2): Reconstruct the model using model-specific sequential functions (defined in `MyModelModel_sequential.py`).
5. **Wrap Redistribution Modules** (Step 3): Add data redistribution functionality to the model to ensure data distribution corresponds to the parallel strategy.
6. **Build Pipeline Parallelism** (Step 4): Construct a pipeline parallel model, placing different stages on corresponding devices.
7. **Wrap Data Parallel Modules** (Step 5): Wrap data parallel modules based on the FSDP library.
8. **Add Checkpoint Wrapping** (Step 6): Add checkpoint functionality to modules based on checkpoint configuration.
Only the API call and the implementations of Step 1 and Step 2 need to be completed using model-specific functions. The other steps are generally implemented by Galvatron.
### Core File Descriptions
The core of adding a new model is the model implementation files. These are the main parts that developers need to implement, defining the structure and implementation of the model.
#### 1. Tensor Parallel Implementation
The tensor parallel implementation is realized through the `MyModelModel_tensor_parallel.py` file, which defines the tensor parallel implementation of the model. Modules in the Sequential model need to be replaced with modules that support tensor parallelism. Galvatron provides different tensor parallel implementations based on different model backends. Specifically, `hf` uses Megatron-TP, and `fa` uses the TP provided by flash-attn.
For `hf`, you need to implement the `MyModelLayer_tp` class and the `MyModelAttention_tp` and `MyModelMLP_tp` classes. For `fa`, you can directly call the `create_mixer_cls` and `create_mlp_cls` methods from flash_attn. You also need to define the `construct_tensor_parallel_model` function to replace the TP model in the full model. Detailed examples can be found in [gpt_hf](https://github.com/PKU-DAIR/Hetu-Galvatron/blob/main/galvatron/models/gpt_hf/GPTModel_tensor_parallel.py) and [gpt_fa](https://github.com/PKU-DAIR/Hetu-Galvatron/blob/main/galvatron/models/gpt_fa/GPTModel_tensor_parallel.py).
##### 1.1 Transformer Layer (`hf` Model Format)
The Transformer layer is implemented through the `MyModelLayer_tp` class:
```python
class MyModelLayer_tp(nn.Module):
def __init__(self, config, layer_number, tp_group=None, sp_group=None):
"""
Parameters:
config: Model configuration object, TransformerConfig
layer_number: Index number of the current layer
tp_group: Tensor parallel communication group, CommGroup
sp_group: Sequence parallel communication group, CommGroup
"""
super().__init__()
self.attention = MyModelAttention_tp(config, layer_number, tp_group, sp_group)
self.mlp = MyModelMLP_tp(config, tp_group)
self.idx = layer_number
def forward(self, hidden_states, attention_mask=None):
# ...
pass
```
This class is mainly responsible for defining the implementation of a Transformer layer, including the attention mechanism and feedforward neural network. Note that defining `self.idx` is necessary for distinguishing layers later, and `config` directly uses the `TransformerConfig` class used when creating the model in the Transformer library.
##### 1.2 Attention Layer (`hf` Model Format)
The attention layer is implemented through the `MyModelAttention_tp` class:
```python
class MyModelAttention_tp(nn.Module):
def __init__(self, config, layer_number, tp_group=None, sp_group=None):
"""
Parameters:
config: Model configuration object, TransformerConfig
layer_number: Index number of the current layer
tp_group: Tensor parallel communication group, CommGroup
sp_group: Sequence parallel communication group, CommGroup
"""
super().__init__()
# ...
megatron_config = core_transformer_config_from_args(args)
self.attention = ParallelAttention(megatron_config, ...)
# ...
def forward(self, hidden_states, attention_mask):
# ...
pass
```
`ParallelAttention` is the attention layer implementation in Megatron-TP modified by Galvatron. In the original Megatron-TP attention layer implementation, three parameters are added: `tp_group`, `sp_group`, and `use_ulysses`, representing the tensor parallel communication group, sequence parallel communication group, and whether to use Ulysses sequence parallelism, respectively. Generally, you can directly refer to the example of [gpt_hf](https://github.com/PKU-DAIR/Hetu-Galvatron/blob/main/galvatron/models/gpt_hf/GPTModel_tensor_parallel.py) for implementation.
##### 1.3 Feedforward Neural Network Layer (`hf` Model Format)
The feedforward neural network layer is implemented through the `MyModelMLP_tp` class:
```python
class MyModelMLP_tp(nn.Module):
def __init__(self, config, tp_group=None):
"""
Parameters:
config: Model configuration object, TransformerConfig
tp_group: Tensor parallel communication group, CommGroup
"""
super().__init__()
# ...
megatron_config = core_transformer_config_from_args(get_args())
self.mlp = ParallelMLP(megatron_config, tp_group = self.tp_group)
# ...
def forward(self, hidden_states):
# ...
pass
```
`ParallelMLP` is the feedforward neural network layer implementation in Megatron-TP modified by Galvatron. In the original Megatron-TP attention layer implementation, the `tp_group` parameter is added to represent the tensor parallel communication group. Generally, you can directly refer to the example of [gpt_hf](https://github.com/PKU-DAIR/Hetu-Galvatron/blob/main/galvatron/models/gpt_hf/GPTModel_tensor_parallel.py) for implementation.
##### 1.4 Constructing Tensor Parallel Model (`hf` Model Format)
The tensor parallel model is constructed through the `construct_tensor_parallel_model` function:
```python
def construct_tensor_parallel_model(model, config, tp_groups_enc, sp_groups_enc):
"""
Convert the model to a tensor parallel version
Parameters:
model: Original model instance
config: Model configuration object, TransformerConfig
tp_groups_enc: List of tensor parallel communication groups for each layer, List[CommGroup]
sp_groups_enc: List of sequence parallel communication groups for each layer, List[CommGroup]
Returns:
Converted tensor parallel model
"""
# ...
pass
```
This function mainly performs three tasks: replacing the Transformer Layer in the model with `MyModelLayer_tp`, replacing the embedding layer in the model with `VocabParallelEmbedding`, and replacing the lm_head in the model with `ColumnParallelLinear`. `VocabParallelEmbedding` and `ColumnParallelLinear` are the embedding layer and linear layer implementations in Megatron-TP modified by Galvatron, with the `tp_group` and `sp_group` parameters added to represent the tensor parallel communication group and sequence parallel communication group. You can also directly refer to the example of [gpt_hf](https://github.com/PKU-DAIR/Hetu-Galvatron/blob/main/galvatron/models/gpt_hf/GPTModel_tensor_parallel.py) for implementation.
Note: The communication groups used in these classes and functions are the CommGroup class customized by Galvatron. If you want to access communication groups generated by torch, please use `tp_group.group` and `sp_group.group`.
##### 1.5 Constructing Tensor Parallel Model (`fa` Model Format)
For `fa`, you only need to implement the `construct_tensor_parallel_model` function. In this function, you need to replace the attention and mlp modules in the Transformer Layer with the `create_mixer_cls` and `create_mlp_cls` methods from flash_attn, replace the embedding layer with the `ParallelGPT2Embeddings` method from flash_attn, and replace the lm_head with the `ColumnParallelLinear` method from flash_attn. A detailed example can be found in [gpt_fa](https://github.com/PKU-DAIR/Hetu-Galvatron/blob/main/galvatron/models/gpt_fa/GPTModel_tensor_parallel.py).
#### 2 Sequential Model Implementation
`MyModelModel_sequential.py` defines the sequential implementation of the model, including the implementation of the forward and backward propagation of the model.
For traditional Transformer models, you need to implement classes such as `MyModelEmbeddings_`, `MyModelLayers_`, `MyModelPreNorm_`, and `MyModelCls_`.
In addition, you need to implement the `construct_sequential_model` function to convert the model to a sequential model and the `MyModelModelInfo` class to define model-related information.
Specifically, the definition and format of each class are as follows:
##### 2.1 Embedding Layer
The embedding layer is implemented through the `MyModelEmbeddings_` class:
```python
class MyModelEmbeddings_(nn.Module):
def __init__(self, model):
"""
Parameters:
model: Model instance
"""
super().__init__()
# ...
def forward(self, tokens, **kwargs):
# ...
pass
```
This class is mainly used to define the embedding layer in the model, including word embedding, position embedding, etc.
Here, the `model` passed into the `__init__` function is the model obtained directly by calling transformers or flash-attn (the `model` in all APIs needs to be the model obtained by calling transformers or flash-attn).
To enhance the robustness of the code, this function also needs to support some additional features: Megatron sequence parallelism and Ulysses sequence parallelism (not supported by `fa`). Detailed examples can be found in [gpt_hf](https://github.com/PKU-DAIR/Hetu-Galvatron/blob/main/galvatron/models/gpt_hf/GPTModel_sequential.py) and [gpt_fa](https://github.com/PKU-DAIR/Hetu-Galvatron/blob/main/galvatron/models/gpt_fa/GPTModel_sequential.py).
Note: When using the `hf` backend, for files with multiple types of Embeddings (e.g., GPT has both Vocab and Position Embeddings), you need to define different Embedding classes to distinguish between these different Embedding parameters. An example of this is shown in [gpt_hf](https://github.com/PKU-DAIR/Hetu-Galvatron/blob/main/galvatron/models/gpt_hf/GPTModel_sequential.py).
##### 2.2 Transformer Layer
The Transformer layer is implemented through the `MyModelLayers_` class:
```python
class MyModelLayers_(nn.Module):
def __init__(self, model, layer_idx):
"""
Parameters:
model: Model instance
layer_idx: Index number of the current layer
"""
super().__init__()
# ...
def forward(self, hidden_states, **kwargs):
# ...
pass
```
This class is mainly used to define the Transformer layer in the model, including the self-attention layer, feedforward neural network layer, etc.
For the `fa` backend, you need to decide whether to add residuals and dropout based on the actual model structure in the code.
##### 2.3 Normalization Layer
The normalization layer is implemented through the `MyModelPreNorm_` class:
```python
class MyModelPreNorm_(nn.Module):
def __init__(self, model):
"""
Parameters:
model: Model instance
"""
super().__init__()
# ...
def forward(self, hidden_states, **kwargs):
# ...
pass
```
This class is mainly used to define the normalization layer before the output layer of the model.
##### 2.4 Output Layer
The output layer is implemented through the `MyModelCls_` class:
```python
class MyModelCls_(nn.Module):
def __init__(self, model):
"""
Parameters:
model: Model instance
"""
super().__init__()
# ...
def forward(self, hidden_states, **kwargs):
# ...
pass
```
This class is mainly used to define the output layer of the model.
To enhance the robustness of the code, this function also needs to support some additional features: Megatron sequence parallelism, Ulysses sequence parallelism (not supported by `fa`), and parallel loss computation (not supported by `fa`). Detailed examples can be found in [gpt_hf](https://github.com/PKU-DAIR/Hetu-Galvatron/blob/main/galvatron/models/gpt_hf/GPTModel_sequential.py) and [gpt_fa](https://github.com/PKU-DAIR/Hetu-Galvatron/blob/main/galvatron/models/gpt_fa/GPTModel_sequential.py).
Note: When using the `hf` backend, to obtain `logits_parallel`, you need to directly reference the `.weight` variable of the original model. This is not allowed in FSDP, so you can place the code for obtaining `logits_parallel` in a separate function, represented by `MyModelLoss_`. An example of this is shown in [gpt_hf](https://github.com/PKU-DAIR/Hetu-Galvatron/blob/main/galvatron/models/gpt_hf/GPTModel_sequential.py).
When implementing these layers, special attention should be paid to ensuring that the input and output tensors (excluding `kwargs`) of the forward function of the same type of layer in the Transformer layer have the same format and size. This is to facilitate updating model information to ensure the correctness of pipeline parallelism. For example, in [gpt_hf](https://github.com/PKU-DAIR/Hetu-Galvatron/blob/main/galvatron/models/gpt_hf/GPTModel_sequential.py), the input and output tensors of the forward function of the Transformer layer have the same format and size, both being `hidden_states`.
##### 2.5 Constructing Sequential Model
The sequential model is constructed through the `construct_sequential_model` function:
```python
def construct_sequential_model(model, config):
"""
Convert the model to a sequential version
Parameters:
model: Original model instance
config: Model configuration object, TransformerConfig
Returns:
Converted sequential model
"""
model_ = PipeSequential()
# ...
```
This function converts the model into a `PipeSequential` format, a special sequential container specifically for pipeline parallelism. Developers only need to add the model sequentially to `PipeSequential` using the `add_module` method.
Note: If `MyModelLoss_` is used, you also need to add a `reset_parameters` method to ensure the model can be initialized correctly.
##### 2.6 Model Information
Model information is implemented through the `MyModelModelInfo` class:
```python
class MyModelModelInfo(ModelInfo):
def __init__(self, config, args):
super(MyModelModelInfo, self).__init__()
# ...
self.set_layernums(layernum_list)
self.set_shapes(layer_shapes_list)
self.set_dtypes(layer_dtypes_list)
self.set_module_types(module_types)
```
In this class, you need to assign four variables: `layernums`, `shapes`, `dtypes`, and `module_types`, representing the number of each type of Transformer layer, the shape of input and output tensors for each type of layer, the data type of input and output tensors for each type of layer, and the name of each layer in the model, respectively.
For `layernums`, you need to assign a list, where each element represents the number of each type of Transformer layer. For example, for GPT, the length of the list is 1 because GPT only has one type of Decoder layer. But for T5, the length of the list is 2 because T5 contains both Encoder and Decoder layers, and these two types of layers have different structures.
For `shapes`, you need to assign a list, where each element represents the shape of input and output tensors for each type of Transformer layer. Typically, this is a list of size `[x, y]`, where `x` represents the number of Transformer layer types, and `y` represents the number of input and output tensors per layer. Each value in the list stores the shape of the input and output tensors.
For `dtypes`, you need to assign a list, where each element represents the data type of input and output tensors for each type of Transformer layer. Typically, this is a list of size `[x, y]`, where `x` represents the number of Transformer layer types, and `y` represents the number of input and output tensors per layer. Each value in the list stores the data type of the input and output tensors.
For `module_types`, you need to assign a list where each element sequentially represents the name of each layer in the model.
#### 3 Hybrid Parallel Implementation
The hybrid parallel implementation is realized through the `MyModelModel_hybrid_parallel.py` file. This file acts as a bridge connecting the model with the Galvatron parallel system, mainly responsible for constructing model instances that support hybrid parallelism.
This file primarily implements four functions: `get_hybrid_parallel_configs`, `construct_hybrid_parallel_model`, `get_mymodel_config`, and `mymodel_model_hp`.
##### 3.1 Getting Hybrid Parallel Configurations
The `get_hybrid_parallel_configs` function is used to obtain hybrid parallel strategies, with the implementation format as follows:
```python
def get_hybrid_parallel_configs(model_config, training_args):
hybrid_parallel_configs = get_hybrid_parallel_configs_api(model_config, training_args, MyModelModelInfo)
return hybrid_parallel_configs
```
This function requires no modifications. It obtains hybrid parallel strategies by calling Galvatron's `get_hybrid_parallel_configs_api` function and returns a dictionary containing hybrid parallel strategy information.
##### 3.2 Constructing Hybrid Parallel Model
The `construct_hybrid_parallel_model` function is used to construct a hybrid parallel model, with the implementation format as follows:
```python
def construct_hybrid_parallel_model(model, model_config, training_args, hybrid_parallel_configs):
# ...
hp_model = construct_hybrid_parallel_model_api(...)
return hp_model
```
This function constructs a hybrid parallel model by calling Galvatron's `construct_hybrid_parallel_model_api` function and returns a model instance that supports hybrid parallelism. Specifically, the parameters and format required by this API function are as follows:
```python
def construct_hybrid_parallel_model_api(
model, # Original model instance
model_config, # Model configuration object
training_args, # Training parameters
hybrid_parallel_configs, # Hybrid parallel configuration
model_info, # Model information class
construct_sequential_model, # Function to construct sequential model
construct_tensor_parallel_model, # Function to construct tensor parallel model
wrap_block_name=None, # List of module names to wrap with FSDP
wrap_checkpoint_block_name=None, # List of module names to add checkpoints
wrap_other_block_name=None, # List of other module names to wrap with FSDP
tied_wte_attr_names=None, # List of attribute names for weight tying
layernorm_name = [], # List of layer normalization names
all_block_name = None, # List of all module names
load_module_func = None, # Function to load module
):
# ...
pass
```
Parameters can be directly referenced from the implementation of [gpt_hf](https://github.com/PKU-DAIR/Hetu-Galvatron/blob/main/galvatron/models/gpt_hf/GPTModel_hybrid_parallel.py) and [gpt_fa](https://github.com/PKU-DAIR/Hetu-Galvatron/blob/main/galvatron/models/gpt_fa/GPTModel_hybrid_parallel.py).
Here, we provide additional explanations for some optional parameters that may cause confusion:
- `wrap_block_name`: A list of Transformer layer module classes that need to be wrapped with FSDP.
- `wrap_checkpoint_block_name`: A list of module names that require checkpoints, usually Transformer layers.
- `wrap_other_block_name`: A list of other module names that need to be wrapped with FSDP, usually layers other than Transformer layers. Note that if multiple Embedding classes are defined, all fine-grained Embedding classes need to be added to the list.
- `tied_wte_attr_names`: A list of attribute names for weight tying. For some models, the parameters of the Vocab Embedding layer and the output layer are the same. For models requiring this feature, developers need to inform Galvatron how to access the Vocab Embedding layer in both the first and last layers of the model. For example, in [gpt_hf](https://github.com/PKU-DAIR/Hetu-Galvatron/blob/main/galvatron/models/gpt_hf/GPTModel_sequential.py), the Embedding layer accesses the `GPTVocabEmbedding_` class via `self.wte`, while the output layer accesses it directly via `self` in the Cls layer. Therefore, `tied_wte_attr_names` is `['wte', '']`.
- `layernorm_name`: A list of names used to identify how Galvatron should access Layernorm in different layers (only the suffix is needed, not the full name). For example, in [gpt_hf](https://github.com/PKU-DAIR/Hetu-Galvatron/blob/main/galvatron/models/gpt_hf), Layernorm is accessed via `self.LayerNorm` in the `GPTAttention_tp` and `GPTMLP_tp` classes, and via `self.ln` in `GPTPreNorm_`. Therefore, `layernorm_name` is `['LayerNorm', 'ln']`.
- `all_block_name`: A list of all module names, usually the union of `wrap_block_name` and `wrap_other_block_name`.
- `load_module_func`: A function to load the module, usually defined as the `load_MyModel_module` function in the `MyModelModel_checkpoint.py` file.
Note: Although `wrap_block_name`, `wrap_checkpoint_block_name`, `wrap_other_block_name`, and `all_block_name` are optional parameters in `construct_hybrid_parallel_model_api`, to ensure that the model can be initialized correctly, these parameters must be provided.
##### 3.3 Getting Model Configuration
The `get_mymodel_config` function is used to get the model configuration, with the implementation format as follows:
```python
def get_mymodel_config(args, overwrite_args=True):
config = config_from_meta(args.model_size)
config = set_model_config(config, args, overwrite_args)
if hasattr(args, 'local_rank') and args.local_rank == 0:
print(config)
return config
```
##### 3.4 Building Hybrid Parallel Model
The `mymodel_model_hp` function is used to build a hybrid parallel model, with the implementation format as follows:
```python
def mymodel_model_hp(config, args):
hybrid_parallel_configs = get_hybrid_parallel_configs(model_config=config, training_args=args)
if args.local_rank == 0:
print("Creating Model...")
mymodel_model = MyModelModel_huggingface(config)
model = construct_hybrid_parallel_model(
model=mymodel_model,
model_config=config,
training_args=args,
hybrid_parallel_configs=hybrid_parallel_configs
)
return model
```
Note that `MyModelModel_huggingface` is the model obtained directly through transformers, not the Galvatron model. When selecting a model in huggingface, choose a model that includes the output layer.
#### 4 Model Checkpoint Save and Load Implementation (Experimental, support hf)
The model checkpoint save and load implementation is realized through the `MyModelModel_checkpoint.py` file, which defines the implementation of model checkpoint saving and loading, including checkpoint save and load functions.
This file needs to implement the `save_MyModel_module` and `load_MyModel_module` functions to implement the saving and loading of model checkpoints.
Galvatron stores and loads model checkpoints layer by layer, so pay attention to loading and storing them layer by layer during implementation.
[llama_hf](https://github.com/PKU-DAIR/Hetu-Galvatron/blob/main/galvatron/models/llama_hf/LlamaModel_checkpoint.py) demonstrates how to implement model checkpoint saving and loading.
### Auxiliary File Descriptions
#### 1 Model Configuration Files
Model configuration files define the model's configuration, including the model's structure, parameter size, etc.
##### 1.1 Model Configuration Storage File
`meta_configs/MyModel-{MODEL_SIZE}b.json`: Model configuration file used to store model configuration information.
##### 1.2 Model Configuration Processing File
- **meta_configs/config_utils.py**: This file mainly handles functions related to model configuration, which mainly include three parts:
- Obtaining model configuration information: Obtain model configuration information by calling the `config_from_meta` function and write it into `TransformerConfig`.
- Modifying model configuration information: Modify model configuration information based on the passed arguments by calling the `set_model_config` function, and modify the model configuration information in the arguments through the `overwrite_megatron_args` and `overwrite_model_args` functions.
- Obtaining model-related information: Obtain the model name through the `model_name` function and obtain the configuration information of each layer of the model through the `model_layer_configs` function.
#### 2 Training Files
Training files mainly define functions related to training, including data loading, model training, etc.
##### 2.1 Main Training File
- **train_dist.py**: This file mainly handles functions related to distributed training.
A complete example is as follows:
```python
def train(args):
# Initialize the distributed training environment
local_rank = args.local_rank
rank = torch.distributed.get_rank()
torch.cuda.set_device(local_rank)
device = torch.device("cuda", local_rank)
world_size = torch.distributed.get_world_size()
config = get_mymodel_config(args)
model = mymodel_model_hp(config, args)
# Create dataset
if local_rank == 0:
print("Creating Dataset...")
# Set dataset-related parameters
set_megatron_args_for_dataset(args, model,
model.sp_groups_whole[0] if args.vocab_sp else model.tp_groups_whole[0],
model.dp_groups_whole[0])
if local_rank == 0:
_print_args("arguments", args)
# Get data iterators
train_data_iterator, valid_data_iterator, test_data_iterator = get_train_valid_test_data_iterators()
# Create optimizer and learning rate scheduler
optimizer, opt_param_scheduler = get_optimizer_and_param_scheduler(model, args)
# Set profiler
path = os.path.dirname(os.path.abspath(__file__))
profiler = GalvatronProfiler(args)
profiler.set_profiler_dist(path, model_layer_configs(config), model_name(config), start_iter=0)
# Record memory usage after model creation
profiler.profile_memory(0, "After creating model")
if local_rank == 0:
print("Start training...")
# Training loop
for iter in range(args.iteration, args.train_iters):
# Get a batch of data
tokens, kwargs, loss_func = get_batch(train_data_iterator)
# Record start time and memory usage
profiler.profile_time_start(iter)
profiler.profile_memory(iter, "Before Forward")
# Prepare input data
input_ids = tokens
batch = [input_ids]
# Forward and backward propagation
loss = model.forward_backward(batch, iter, profiler,
loss_func=loss_func,
**kwargs)
# Record memory usage after backward propagation
profiler.profile_memory(iter, "After Backward")
# Gradient clipping
total_norm = clip_grad_norm(model, args.clip_grad)
# Optimizer step
optimizer.step()
# Learning rate scheduler step
opt_param_scheduler.step(increment=args.global_batch_size)
# Record memory usage after optimizer step
profiler.profile_memory(iter, "After optimizer_step")
# Zero gradients
optimizer.zero_grad()
# Update profiler statistics
profiler.post_profile_memory(iter)
# Get current learning rate
for param_group in optimizer.param_groups:
learning_rate = param_group['lr']
# Record performance metrics for this iteration
profiler.profile_time_end(iter, loss, learning_rate, total_norm)
# Synchronize all processes
torch.distributed.barrier()
# Periodically save model checkpoints
if args.save != None and (iter + 1) % args.save_interval == 0:
save_llama_module(args.save, model, optimizer, opt_param_scheduler, iter + 1, args)
if __name__ == '__main__':
# Initialize Galvatron training environment
args = initialize_galvatron(model_args, mode='train_dist')
# Set random seed for reproducibility
set_seed()
# Start training
train(args)
```
- **train_dist_random.py**: This file mainly handles functions related to distributed training, similar to `train_dist.py`, but uses random data for training.
##### 2.2 Data Loading Files
- **dataloader.py**: This file mainly handles functions related to data loading, which mainly include two parts:
- Random Data Loading: Create a dataset that generates random tokens and create a `collate_fn` function to convert random tokens into model inputs. Below is an example of random data loading:
```python
def random_get_ltor_masks_and_position_ids(data):
"""Build masks and position id for left to right model."""
micro_batch_size, seq_length = data.size()
att_mask_batch = 1
attention_mask = torch.tril(torch.ones(
(att_mask_batch, seq_length, seq_length), device=data.device)).view(
att_mask_batch, 1, seq_length, seq_length)
attention_mask = (attention_mask < 0.5)
return attention_mask
def random_collate_fn(batch):
# Stack data in the batch and return data in the corresponding format
tokens_ = torch.stack(batch, dim=0)
labels = tokens_[:, 1:].contiguous()
tokens = tokens_[:, :-1].contiguous()
args = get_args()
if not args.use_flash_attn:
attention_mask = random_get_ltor_masks_and_position_ids(tokens)
else:
attention_mask = None
return tokens, {"attention_mask":attention_mask, "labels" : labels}, None
class DataLoaderForMyModel(Dataset):
def __init__(self, args, device, dataset_size = 2560 * 16):
self.vocab_size = args.vocab_size
self.sentence_length = args.seq_length
self.dataset_size = dataset_size
# Randomly generate the actual length of each sample (between 1 and the maximum length)
self.data_length = np.random.randint(1,self.sentence_length+1,(self.dataset_size,))
self.device = device
# Generate random input data
self.input_ids = []
for i in range(self.dataset_size):
sentence = np.random.randint(0,self.vocab_size,(self.sentence_length,))
sentence[self.data_length[i]:] = 0
mask = np.ones((self.sentence_length,))
mask[self.data_length[i]:] = 0
padding_sentence = np.zeros(self.sentence_length + 1, dtype=sentence.dtype)
padding_sentence[:self.sentence_length] = sentence
self.input_ids.append(padding_sentence)
self.input_ids = np.array(self.input_ids)
def __len__(self):
return self.dataset_size
def __getitem__(self, idx):
if idx >= self.dataset_size:
raise IndexError
input_ids = torch.LongTensor(self.input_ids[idx]).to(self.device)
return input_ids
```
The specific `trainloader` is created by the following code:
```python
trainloader = distributed_dataloader(
dataset=DataLoaderForGPT(args, device),
global_bsz=args.global_train_batch_size,
shuffle=True,
args=args,
group = model.dp_groups_whole[0].group,
collate_fn = random_collate_fn
)
```
The `distributed_dataloader` function is a distributed data loader provided by Galvatron, used to create distributed data loaders.
- Real Data Loading: Create a real data loader and design a loss calculation function.
The implementation of real data loading is based on the Megatron dataset and mainly includes functions such as `train_valid_test_datasets_provider`, `get_train_valid_test_data_iterators`, `get_batch`, and `loss_func`. A concrete implementation example can be found in [gpt_hf](https://github.com/PKU-DAIR/Hetu-Galvatron/blob/main/galvatron/models/gpt_hf/dataloader.py).
The main point to note is that the `get_batch` function returns a tuple with three elements:
- Input Data: Usually a sequence of tokens, of type `torch.Tensor`.
- Other Input Data: Usually a dictionary type, containing `position_ids`, `attention_mask`, `labels`, etc.
- Loss Calculation Function: The loss can be calculated directly by calling the `loss_func(output_tensor)` function.
Note: The input data here should be consistent with the input data format of the Embedding layer in the `MyModelModel_sequential.py` file. Other data is passed between model layers as `**kwargs`.
##### 2.3 Profiling File
- **profiler.py**: This file mainly handles functions related to profiling, with content as follows:
```python
if __name__ == '__main__':
# Initialize Galvatron profiling environment
args = initialize_galvatron(model_args, mode='profile')
# Load model configuration
config = get_mymodel_config(args, overwrite_args=False)
# Create profiler instance
profiler = GalvatronProfiler(args)
# Get the directory path of the current file
path = os.path.dirname(os.path.abspath(__file__))
# Set profiler launcher
profiler.set_profiler_launcher(path, layernum_arg_names(), model_name(config))
# Launch profiling scripts
profiler.launch_profiling_scripts()
# Process collected profiling data
profiler.process_profiled_data()
```
##### 2.4 Strategy Search File
- **search_dist.py**: This file is primarily responsible for functions related to strategy search. Its contents are as follows:
```python
if __name__ == '__main__':
args = initialize_galvatron(model_args, mode='search')
config = get_mymodel_config(args, overwrite_args=True)
path = os.path.dirname(os.path.abspath(__file__))
print(args)
print(config)
# Create an instance of the strategy search engine
search_engine = GalvatronSearchEngine(args)
# Set basic information for the search engine
search_engine.set_search_engine_info(path, model_layer_configs(config), model_name(config))
# Initialize the search engine
search_engine.initialize_search_engine()
# Perform strategy search
search_engine.parallelism_optimization()
```
#### 3 Script Files
The `scripts` folder mainly contains script files used to implement model training, performance analysis, strategy search, and other functions.
It mainly includes five different scripts:
- `profile_computation.sh`: Used for performance analysis, calculating the computational performance of the model under different configurations.
- `profile_memory.sh`: Used for performance analysis, calculating the memory usage of the model under different configurations.
- `search_dist.sh`: Used for strategy search, finding the optimal strategy for the model under different configurations.
- `train_dist.sh`: Used for model training.
- `train_dist_random.sh`: Used for model training with random data.

However, it is unrealistic to measure the corresponding profiling data for all models and hardware devices, so we encourage you to measure different hardware and models and submit PRs. The specific profiling method can be referred to the [Profiling with Galvatron](../3_quick_start/quick_start.html#profiling-with-galvatron) section.

# 概述
Galvatron 是一个为 Transformer 模型（包括大语言模型 LLMs）设计的自动分布式训练系统。它利用先进的自动并行技术提供卓越的训练效率。本仓库包含了 Galvatron-2 的官方实现，这是我们最新版本，增加了多项新特性。
## 主要特点
### (1) 通过自动并行提升效率
#### 扩展的并行搜索空间
整合了分布式训练中多个流行的并行维度，包括 DP（数据并行）、SDP（分片数据并行，支持 ZeRO-1, ZeRO-2 和 ZeRO-3）、PP（流水线并行，支持 GPipe 和 Pipedream-flush / 1F1B-flush）、TP（张量并行）、SP（序列并行，支持 Megatron-SP 和 Deepspeed-Ulysses）。同时将 CKPT（激活检查点）作为一个特殊的并行维度。
#### 细粒度混合并行
Galvatron的混合并行方法代表了分布式训练优化的重大进步。系统不采用统一的策略，而是实现了层级并行化，允许每个transformer层使用独立的并行策略组合。这种精细的方法通过适应每一层特定的计算和内存需求，确保了最佳的资源利用。
系统动态地组合多种并行类型，仔细权衡计算、内存使用和通信开销之间的关系。这种混合方法在处理复杂模型架构时特别有效，因为不同的层可能从不同的并行化策略中受益。
#### 高效的自动并行优化
Galvatron效率的核心在于其复杂的优化引擎。通过精确的成本建模，系统准确估计计算需求，预测内存使用模式，并为不同的并行化策略建立通信开销模型。这种全面的建模实现了策略选择的智能决策。
优化过程采用基于动态规划的高级搜索算法，同时考虑多个目标，包括内存效率和通信成本。系统自动适应硬件约束，同时确保最佳性能。
### (2) 通用性
Galvatron的通用性覆盖了整个Transformer架构谱系。在语言模型领域，它擅长处理从传统的BERT式编码器和GPT解码器到复杂的T5式编码器-解码器模型的各类架构。对于大型语言模型(LLMs)，系统提供专门的优化，通过谨慎管理内存和计算资源，实现了对具有万亿参数模型的高效训练。
系统的能力不仅限于语言模型，还扩展到视觉transformer架构。Galvatron可以在保持其效率的同时，适应每种架构的独特需求。在未来的版本中，Galvatron还将支持多模态架构。
### (3) 用户友好界面
尽管具有复杂的底层技术，Galvatron优先考虑用户可访问性。用户只需进行最少的代码更改即可开始训练，并得到全面文档和实用示例的支持。系统还提供与流行框架数据加载器的无缝集成，以及强大的检查点管理功能，使其成为研究和生产环境的实用选择。
## 系统架构
Galvatron的架构由三个紧密集成的核心模块组成，共同协作提供高效的分布式训练：
### (1) Galvatron 性能分析器
性能分析器作为系统的基础，对硬件能力和模型特征进行全面分析。在硬件方面，它测量设备间的通信带宽和每个设备的计算吞吐量。对于模型分析，它分析不同模型组件的计算模式、内存需求和通信需求。这些详细的分析信息为智能策略决策提供基础。
### (2) Galvatron 搜索引擎
搜索引擎是系统的大脑，利用分析数据发现最优并行化策略。它采用复杂的算法探索可能的并行配置空间，并自动为模型的每一层确定最高效的并行策略组合。
### (3) Galvatron 运行时框架
运行时框架实现执行层，将高层并行化策略转换为高效的分布式操作。该框架提供了一个健壮且灵活的执行环境，能够适应不同的硬件配置和模型架构。
### 工作流程
这三个模块无缝协作，简化分布式训练过程。用户只需提供硬件环境和Transformer模型配置。
系统自动处理分布式训练优化的所有方面，从初始分析到策略选择再到高效执行。这种架构确保了易用性和高性能，使复杂的分布式训练对更广泛的用户可访问，同时保持了高级应用所需的灵活性。
通过这种模块化设计，Galvatron在自动化和定制化之间实现了平衡，既能简单部署标准场景，又能对特殊需求进行详细控制。

# 快速入门
## 使用 Galvatron 进行性能分析
使用 Galvatron 的第一步是对硬件环境和模型计算时间进行性能分析。Galvatron 会自动将分析结果保存到配置文件中。
(1) 首先，要对硬件环境进行性能分析，```cd galvatron/profile_hardware```，将主机地址写入 ```hostfile```，在 ```scripts/profile_hardware.sh``` 中设置 ```NUM_NODES, NUM_GPUS_PER_NODE, MPI_PATH```，然后运行：
````shell
sh scripts/profile_hardware.sh
````
Galvatron 将调用 [nccl-tests](https://github.com/NVIDIA/nccl-tests) 或 [pytorch profiler](https://pytorch.org/tutorials/recipes/recipes/profiler_recipe.html) 来分析通信带宽。你可以通过在 ```scripts/profile_hardware.sh``` 中将 ```--backend``` 设置为 ```nccl``` 或 ```torch``` 来选择其中之一。
对于```nccl```格式，用户需要设置以下变量：
- ```nccl_test_dir```: 用于指定nccl-tests的目录
- ```mpi_path```: 用于指定mpi的安装路径
- ```start_mb```: 用于指定开始分析的通信带宽大小
- ```end_mb```: 用于指定结束分析的通信带宽大小
- ```scale```: 用于指定通信带宽的缩放因子
- ```hostfile```: 用于指定主机文件，该文件中需要包含所有节点的IP地址或主机名
此外用户还需要设置环境变量```NCCLTEST_OTHER_ARGS```，该变量用于指定nccl-tests需要的额外环境变量，例如可以用于指定nccl-tests的IB设备。
对于```torch```格式，用户需要设置以下变量：
- ```master_addr```: 用于指定主节点的IP地址或主机名
- ```master_port```: 用于指定主节点的端口号
- ```node_rank```: 用于指定当前节点的rank
- ```envs```: 用于指定环境变量
在```torch```格式下，运行脚本并不会直接profile带宽，而是会在```scripts```目录下生成四个脚本，分别是```profile_allreduce```, ```profile_p2p```, ```profile_allreduce_sp```, ```profile_all2all_sp```。用户需要在所有节点依次运行这四个脚本，来获取不同通信模式下的带宽。
注意这里```master_addr```、```master_port```、```node_rank```可以设置成```'$xxx'```的形式，这样在生成脚本的时候保留变量名，运行脚本的时候再从环境变量中获取。
Gavlatron在默认脚本中提供了不同```backend```的配置文件，用户可以在此基础上进行修改。
(2) 其次，要分析模型计算时间和内存使用情况，```cd galvatron/models/model_name``` 并运行：
````shell
sh scripts/profile_computation.sh
sh scripts/profile_memory.sh
````
## 使用 Galvatron 进行并行优化
在对环境进行性能分析后，Galvatron 能够自动为给定的 Transformer 模型优化并行策略。给定内存预算，Galvatron 提供具有最大吞吐量的细粒度混合并行策略。优化后的并行策略将保存在 `galvatron/models/model_name/configs` 中用于训练。你可以使用提供的最优策略训练模型以获得最佳吞吐量。
要进行并行优化，```cd galvatron/models/model_name```，在 ```scripts/search_dist.sh``` 中自定义 ```NUM_NODES, NUM_GPUS_PER_NODE, MEMORY```，运行：
````shell
sh scripts/search_dist.sh
````
该脚本将在后台自动运行搜索代码，并在以 `Search` 开头的文件中生成搜索日志结果。当你在文件中看到以下标记时，表示搜索已结束，在此之前无需执行其他命令：
````
========================= Galvatron Search Engine End Searching =========================
````
搜索结束后，获得的并行策略将生成在 `configs` 文件夹中。策略以 JSON 格式存储，文件名以 `galvatron_config_{model_size}_` 开头。
有关自定义并行优化的更多使用详情，请参见 [Galvatron 模型使用](../4_galvatron_model_usage/galvatron_model_usage_zh.html#id3)。
## 使用 Galvatron 进行训练
Galvatron 提供了一种简单的方法来以细粒度混合并行方式训练 Transformer 模型。你可以通过指定参数 ```galvatron_config_path``` 使用搜索到的最优并行策略来训练 Transformer 模型以获得最佳吞吐量，或者按照自己的喜好使用任何并行策略。Galvatron 支持两种混合并行配置模式，包括 JSON 配置模式和全局配置模式。你可以通过修改少量参数来指定并行策略。
要使用 Galvatron 训练模型，```cd galvatron/models/model_name```，设置 ```NUM_NODES, NUM_GPUS_PER_NODE, MASTER_ADDR, MASTER_PORT, NODE_RANK```，然后运行：
````shell
sh scripts/train_dist_random.sh
````
使用 `--galvatron_config_path` 参数来应用从搜索引擎获得的并行策略。如果你已经准备好相关的数据集和检查点，可以通过修改和运行 `scripts/train_dist.sh` 来完成实际训练。
提示：在继续之前，请确认是否需要使用 `--set_seqlen_manually` 参数来手动指定训练模型的序列长度。
详细指南和更多自定义训练选项请参见 [Galvatron 模型使用](../4_galvatron_model_usage/galvatron_model_usage_zh.html#id9)。

# Galvatron 模型使用
Galvatron 为多个主流模型提供了示例代码，展示了如何重写 Transformer 模型以适应 Galvatron 的自动优化 API。此外，你可以从这些模型快速开始，在自己的硬件环境中优化并行策略。通过 ```cd model_name``` 进入模型目录开始。
## 使用 Galvatron 进行性能分析
使用 Galvatron 的第一步是对硬件环境和模型前向计算时间进行性能分析。
(1) 首先，对硬件环境进行性能分析。详细信息请参考 [快速入门](../3_quick_start/quick_start_zh.html#galvatron)。在运行模型目录中的任何脚本之前，请确保已完成硬件环境的性能分析！
(2) 其次，对模型计算时间进行性能分析：
````shell
sh scripts/profile_computation.sh
````
对于 [Galvatron Model Zoo](https://github.com/PKU-DAIR/Hetu-Galvatron/blob/main/galvatron/models) 中的模型和配置，性能分析步骤已经完成。对于用户自定义模型，需要额外进行模型内存消耗的性能分析：
````shell
sh scripts/profile_memory.sh
````
### 其他性能分析参数
通过设置 `profile_min_batch_size`、`profile_max_batch_size` 和 `profile_batch_size_step`，你可以控制时间性能分析期间使用的批量大小。具体来说，时间性能分析将使用 `range(profile_min_batch_size, profile_max_batch_size + 1, profile_batch_size_step)` 范围内的批量大小。类似地，通过设置 `profile_min_seq_length`、`profile_max_seq_length`、`profile_seq_length_step`，你可以控制时间和内存性能分析期间使用的序列长度。前者应与 `profile_mode == 'batch'` 一起使用，后者与 `profile_mode == 'sequence'` 一起使用。而对于`static`模式，则需要通过设置`profile_batch_size`来控制批量大小，设置`profile_seq_length_list`来控制序列长度。关于 `profile_mode` 的更多细节将在后面讨论。
## 使用 Galvatron 进行并行优化
给定集群和内存预算，Galvatron 搜索引擎将自动生成最优并行策略。优化后的并行策略将以 JSON 文件形式保存在 `configs` 中用于训练。要使用 Galvatron 搜索引擎进行并行优化，运行：
````shell
sh scripts/search_dist.sh
````
你可以自定义多个并行优化选项：
### 模型配置
你可以设置 `model_size` 来轻松获取预定义的模型配置。你也可以自定义模型配置：将 `set_model_config_manually` 设为 `1` 并手动指定模型配置，或将 `set_layernum_manually` 设为 `1` 仅手动指定层数。
### 集群大小和内存约束
Galvatron 可以在具有相同 GPU 数量的多个节点上进行搜索。你需要设置 `num_nodes`、`num_gpus_per_node` 和 `memory_constraint`（每个 GPU 的内存预算）。
### 批量大小和分块
对于批量大小控制，搜索过程从 `min_bsz` 开始，以 `bsz_scale` 的比例增长，到 `max_bsz` 结束。你也可以设置 `settle_bsz` 来找到批量大小为 `settle_bsz` 时的最优策略。此外，你可以配置 `settle_chunk` 来确定分块大小为 `settle_chunk` 时的最优策略。
### 并行搜索空间
Galvatron 在搜索空间中包含五个并行维度（`dp` 用于数据并行，`sdp` 用于分片数据并行，`tp&vtp` 用于张量并行，`pp` 用于流水线并行，以及 `ckpt` 用于激活检查点）。你可以使用预定义的搜索空间（`full` 用于在 Galvatron 引入的所有并行维度上进行逐层优化，`3d` 用于在 `(dp,tp,pp)` 上进行模型级优化，以及其他用于在相应维度组合上进行逐层优化的选项）。你可以通过将 `disable_*` 设为 `1` 来禁用任何并行维度。
有关搜索参数的完整列表，请参考 [arguments.py](https://github.com/PKU-DAIR/Hetu-Galvatron/blob/main/galvatron/core/arguments.py) 中的 ```galvatron_search_args```。
### 其他搜索参数
设置 `sequence-parallel` 以在构建成本模型时考虑 `Megatron-TP-SP` 方法。
设置 `fine_grained_mode` 为 `0` / `1`（默认：`1`）以禁用/启用细粒度并行策略和搜索。对于前者，搜索引擎将找到一个全局并行策略，即对所有层应用相同的并行策略。对于后者，它指的是标准的细粒度并行策略搜索。
设置 `profile_mode` 为 `static` / `batch` / `sequence`（默认：`static`）以确定构建成本模型时的计算时间和内存估算方法。`static` 表示计算时间与批量大小成比例增长。相比之下，`batch` 表示计算时间与批量大小线性增长。具体来说，我们将使用 $\alpha-\beta$ 模型基于分析数据拟合线性函数。为确保准确性，使用 `batch` 时，我们需要对同一层类型的 8 个不同批量大小进行性能分析。此外，`sequence` 使用分析数据来模拟其他序列长度的内存和时间性能。在实践中，搜索参数中的 `profile_mode` 通常应与性能分析参数匹配。使用 `static` 或 `batch` 模式时，用户还需要确保序列长度一致。但使用 `sequence` 模式时则不需要。
设置 `sp_space` 为 `tp+sp` / `tp`（默认：`tp`）以确定序列并行的搜索空间。`tp+sp` 表示同时考虑 Megatron-SP 和 Ulysses，而 `tp` 表示仅考虑 Megatron-SP。
设置 `no_global_memory_buffer` 以禁用使用 Megatron-SP 时全局内存的 all-gather 缓冲区估算。在 Megatron-SP 中，会分配一个缓冲区来存储 all-gather 通信操作的结果。这个内存不会被释放，随着序列长度的增加，这个缓冲区的内存使用量可能会变得很大。
此外，为了加速搜索，我们还提供了并行搜索选项，可以通过开启`parallel_search`启用并行搜索，并使用`worker`参数设置并行搜索的线程数，默认是2xCPU核心数，此外，我们还提供了`log_dir`参数设置搜索日志保存路径。
**`sp_space` 设为 `tp+sp` 与 `tp_consec` 设为 0 不兼容。`tp_consec` 的搜索很少见，我们计划在未来版本中移除它。**
## 使用 Galvatron 进行训练
要使用 Galvatron 训练模型，运行：
````shell
sh scripts/train_dist.sh
````
你可以自定义多个训练选项：
### 检查点加载和保存
#### 检查点加载
Galvatron 支持加载 Huggingface 模型并适应细粒度并行策略。通过简单的权重转换过程，可以执行以下命令来实现：
````shell
cd tools
bash convert_{MODEL_TYPE}_h2g.sh
````
你需要修改脚本，设置 INPUT_PATH 和 OUTPUT_PATH 分别为转换前后存储检查点文件的目录。
请注意，权重转换与并行策略无关。
接下来，你可以在训练脚本中使用以下参数来加载检查点：
````shell
--initialize_on_meta 1 \
--load ${OUTPUT_PATH}
````
对于之前由 Galvatron 保存的检查点，你可以通过添加 ```--load_distributed``` 来加载。注意，这种方法要求当前的并行策略与保存检查点时使用的并行策略一致。
#### 检查点保存
Galvatron 支持在训练期间保存检查点。你可以在训练脚本中使用以下参数来保存检查点：
````shell
--save ${OUTPUT_PATH}
--save-interval ${SAVE_INTERVAL}
````
Galvatron 将在目标目录中存储指定并行策略的分布式检查点，包括参数和优化器状态。
要将已保存的分布式 Galvatron 检查点转换为 Hugging Face 格式，你可以使用以下命令：
````shell
cd tools
bash convert_{MODEL_TYPE}_g2h.sh
````
### 使用数据集训练
Galvatron 支持使用 Megatron 数据集，其预处理和使用方法与 [Megatron](https://github.com/NVIDIA/Megatron-LM) 兼容。
### 模型配置
你可以设置 `model_size` 来轻松获取预定义的模型配置。你也可以自定义模型配置：将 `set_model_config_manually` 设为 `1` 并手动指定模型配置，将 `set_layernum_manually` 设为 `1` 并手动指定层数，将 `set_seqlen_manually` 设为 `1` 并手动指定序列长度。
### 集群环境
Galvatron 可以在具有相同 GPU 数量的多个节点上进行训练。你应该根据环境设置 ```NUM_NODES, NUM_GPUS_PER_NODE, MASTER_ADDR, MASTER_PORT, NODE_RANK```。
### 并行策略
在使用 Galvatron 进行分布式训练时，你可以选择使用并行优化搜索到的最优并行策略来获得最佳吞吐量，或者按照自己的喜好指定混合并行策略。
#### JSON 配置模式 [推荐]
JSON 配置模式是一种**推荐的**逐层混合并行训练模式，通过将参数 `galvatron_config_path` 指定为 `configs` 目录中的配置路径来激活。
