The aim of this tutorial is to draw parallels, as well as to outline potential differences, to empower the user to switch seamlessly between these two frameworks. <Tip> To switch between the frameworks, we recommend launching code 🤗 `accelerate launch` passing in the correct config file with `--config_file`, or passing in the respective arguments directly for [FSDP and DeepSpeed](../package_reference/cli#accelerate-launch) . Example 🤗 Accelerate configurations can be found here for [DeepSpeed](../usage_guides/deepspeed#accelerate-deepspeed-plugin) and [FSDP](../usage_guides/fsdp#how-it-works-out-of-the-box), or in the [example zoo under "Launch Configurations"](../usage_guides/explore) </Tip> <Tip warning={true}> This tutorial is for single-node, multi-GPU, scenarios only. </Tip> ## Configuring Functionalities Model tensors are split into different GPUs in an attempt to scale up model sizes; this is termed *sharding* in FSDP, and *partitioning* in DeepSpeed. FSDP sharding and DeepSpeed ZeRO (partitioning) stages are configured by `--fsdp_sharding_strategy`, and `--zero_stage`, respectively. In particular, FSDP `FULL_SHARD` maps to DeepSpeed ZeRO stage `3`; see this [comprehensive mapping between FSDP sharding and DeepSpeed ZeRO settings](../usage_guides/fsdp#mapping-between-fsdp-sharding-strategies-and-deepspeed-zero-stages). The below table summarizes and groups similar settings: Group | Framework | Configuration | Example | Restrictions (if any) --|--|--|--|-- sharding / partitioning | FSDP<br>DeepSpeed | `--fsdp_sharding_strategy`<br>`--zero_stage` | `1` (`FULL_SHARD`) <br>`3` | offload | FSDP<br>DeepSpeed | `--fsdp_offload_params`<br>`--offload_param_device`<br>`--offload_optimizer_device` | `true`<br>`cpu`<br>`cpu` | all or nothing <br><br> model loading | FSDP<br>DeepSpeed | <span style="white-space:nowrap;">`--fsdp_cpu_ram_efficient_loading`</span><br>`--zero3_init_flag` | `true`<br>`true` | <br>only ZeRO 3 efficient checkpointing | FSDP<br>DeepSpeed | `--fsdp_state_dict_type`<br>`--zero3_save_16bit_model` | `SHARDED_STATE_DICT`<br>`true` | <br>only ZeRO 3 weights prefetching | FSDP<br><br>DeepSpeed | `--fsdp_forward_prefetch`<br>`--fsdp_backward_prefetch`<br>None | `true`<br>`BACKWARD_PRE` | <br><br> model | FSDP<br><br>DeepSpeed | `--fsdp_auto_wrap_policy`<br><span style="white-space:nowrap;">`--fsdp_transformer_layer_cls_to_wrap`</span><br>None | `TRANSFORMER_BASED_WRAP`<br><Layer Class> |<br>Usually not needed <br>Transparent to user. parameters summoning | FSDP<br>DeepSpeed | `--fsdp_use_orig_params`<br>None | `true` | required for `torch.compile`<br>Transparent to user parameters syncing | FSDP<br>DeepSpeed | `--fsdp_sync_module_states`<br>None | `true` | training | FSDP<br>DeepSpeed | None<br>`--gradient_accumulation_steps`<br>`--gradient_clipping` | <br>`auto`<br>`auto` | Transparent to user For detailed descriptions of the above, refer to [🤗 `Accelerate` launch documentation](../package_reference/cli#accelerate-launch). <Tip> To access other DeepSpeed configurations, such as mixed precision settings, you need to pass in a `--deepspeed_config_file`, see the [documentation](../usage_guides/deepspeed#deepspeed-config-file). DeepSpeed can be also configured via [`DeepSpeedPlugin`], e.g., `DeepSpeedPlugin.zero_stage` is equivalent of `--zero_stage`, and `DeepSpeedPlugin.hf_ds_config` can be used to pass `--deepeed_config_file.` </Tip> <Tip> FSDP can be also configured via [`FullyShardedDataParallelPlugin`], e.g., `FullyShardedDataParallelPlugin.sharding_strategy` is equivalent of `--fsdp_sharding_strategy`. </Tip> ### Checkpointing Do note that while FSDP can be configured via `--fsdp_state_dict_type` to save either full / sharded checkpoints. <Tip> For DeepSpeed Zero3, one could pass a `--zero3_save_16bit_model true`, which conveniently consolidates the model to a single rank and saves; this is the FSDP equivalent of `fsdp_state_dict_type: FULL_STATE_DICT`. </Tip> <Tip warning={true}> For large models, consolidating the model to a single rank can be very slow. </Tip> <Tip> For quicker checkpointing, for FSDP use `fsdp_state_dict_type: SHARDED_STATE_DICT`, and for DeepSpeed Zero3 [use the `zero_to_fp32.py` script to post-convert sharded checkpoints](https://www.deepspeed.ai/tutorials/zero/#extracting-weights). </Tip> ### Offloading FSDP only allows *all-or-nothing* offload (i.e., either offload parameters, gradients, and optimizer, or keep them all in GPU), but DeepSpeed can offload parameters and optimizer differently. Furthermore, DeepSpeed also supports [offloading to NVME](https://www.deepspeed.ai/docs/config-json/#parameter-offloading). ### Prefetching FSDP allows two prefetching configurations `--fsdp_forward_prefetch` and `--fsdp_backward_prefetch` to improve overlap of comms / computation at a cost of extra memory, see [FSDP documentation](https://pytorch.org/docs/stable/fsdp.html). For DeepSpeed, the prefetching will be turned on when needed, and it turns on depending on certain hyper-params like `stage3_param_persistence_threshold`, `stage3_max_reuse_distance`, etc, [that can be configured for Zero3](https://www.deepspeed.ai/docs/config-json/#parameter-offloading); 🤗 `accelerate` may set these hyper-params automatically if you don't set those explicitly in the deepspeed config file. <Tip> For FSDP set `fsdp_backward_prefetch: BACKWARD_PRE` for improved throughputs if memory allows. </Tip> ### Model Loading While FSDP require an explicit `--fsdp_cpu_ram_efficient_loading true` to activate efficient model loading, 🤗 `transformers` will activate the similar feature whenever DeepSpeed Zero3 is used. <Tip> For FSDP, whenever setting `--fsdp_cpu_ram_efficient_loading true`, 🤗 `accelerate` will automatically set `sync_module_states` to true. For RAM efficient loading the weights will be loaded only in a singe rank, and thus requires `sync_module_states` to broadcast weights to other ranks. </Tip> ### Model FSDP requires an explicit `--fsdp_auto_wrap_policy` for the algorithm to decide how to schedule the all-gather and reduce-scatter operations. But for DeepSpeed this is transparent to the user. <Tip> For FSDP, simply set `fsdp_auto_wrap_policy: TRANSFORMER_BASED_WRAP`. With the latest [`transformers`] versions, we try our best to figure out the suitable `fsdp_transformer_layer_cls_to_wrap` for HF transformers models. However, if you get an error regarding it, please specify this. </Tip> ### Parameters Summoning FSDP requires an explicit `--fsdp_use_orig_params` flag if using `torch.compile`, see [the pytorch documenation](https://pytorch.org/docs/stable/fsdp.html#module-torch.distributed.fsdp). For DeepSpeed this is transparent to the user. <Tip> For FSDP, when using `torch.compile` please set `fsdp_use_orig_params: True`. </Tip> ## Training Deepspeed requires explicit `--gradient_accumulation_steps` and `--gradient_clipping` flags. For FSDP this is transparent to the user. <Tip> When using DeepSpeed, set `gradient_accumulation_steps: "auto"` and `gradient_clipping: "auto"` to automatically pick up values set in the [`Accelerator`] or [`TrainingArguments`] (if using `transformers`). </Tip> ## On Differences in Data Precision Handling To discuss the how data precision is handled in both FSDP and Deepspeed, it is instructive to first give an overview of how model parameters are handled in these frameworks. Before the model / optimizer parameters are distributed across GPUs, parameter preparation is involved to first "flatten" them to one-dimensional [`torch.Tensor`](https://pytorch.org/docs/stable/tensors.html#torch-tensor). The implementation of FSDP / DeepSpeed varies in the respect of the `dtype` in which these "flattened" parameters are stored, and there are ramifications with regards to how [`torch.Optimizer`](https://pytorch.org/docs/stable/optim.html#module-torch.optim) allocate their `dtype`s. The table below outlines the processes for both frameworks; the "Local" column indicates the process occurring at a per-gpu level, therefore any memory overheads by upcasting should be understood to be amortized by the number of gpus used. <Tip> As a rule of thumb, for stable training with automatic mixed precision, all the trainable parameters have to be in `torch.float32`. </Tip> Process | Local | Framework | Details --|--|--|-- Loading, i.e., [`AutoModel.from_pretrained(..., torch_dtype=torch_dtype)`] | Preparation, i.e., creation of "flat params" | ✅ | FSDP<br>DeepSpeed | created in `torch_dtype`.<br> disregards `torch_dtype`, created in `float32`. Optimizer initialization | ✅ | FSDP<br>DeepSpeed | creates parameters in `torch_dtype`<br> creates parameters in `float32` Training Step, i.e, forward, backward, reduction | | FSDP<br>DeepSpeed | follows [`MixedPrecision`](https://pytorch.org/docs/stable/fsdp.html#torch.distributed.fsdp.MixedPrecision)<br> follows `deepspeed_config_file` mixed precision settings. Optimizer (Pre-Step) | ✅ | FSDP<br>DeepSpeed | upcasting (if any) to `torch_dtype`<br>upcasted to `float32` Optimizer (Actual Step) | ✅ | FSDP<br>DeepSpeed | occurs in `torch_dtype` <br> occurs in `float32`. <Tip warning={true}> Therefore when using DeepSpeed a small number of GPUs, be aware of potentially significant memory overheads due to the upcasting during preperation. </Tip> <Tip> With FSDP, in the absence of mixed precision, it is possible to operate the [`torch.Optimizer`](https://pytorch.org/docs/stable/optim.html#module-torch.optim) in low precision `torch_dtype`, which may be helpful when using small number of GPUs. </Tip> <Tip warning={true}> With mixed precision, FSDP and DeepSpeed will upcast in the model preparation step (c.f. table above). But do note that FSDP will then save checkpoints in the upcasted precision; Deepspeed may still save low precision checkpoints if `--zero3_save_16bit_model` is specified. </Tip> To clarify the above table consider the concrete examples below; the optimizer pre- and actual step combined for brevity. With FSDP it is possible to operate in the two modes shown below, but DeepSpeed can only operate in one. Framework | Model Loading (`torch_dtype`) | Mixed Precision | Preparation (Local) | Training | Optimizer (Local) --|--|--|--|--|-- FSDP | bf16 | default (none) | bf16 | bf16 | bf16 FSDP | bf16 | bf16 | fp32 | bf16 | fp32 DeepSpeed | bf16 | bf16 | fp32 | bf16 | fp32

So, it is expected to bring performance benefit for Intel CPU generations with AVX-512 or above while CPUs with only AVX2 (e.g., AMD CPUs or older Intel CPUs) might result in a better performance under IPEX, but not guaranteed. IPEX provides performance optimizations for CPU training with both Float32 and BFloat16. The usage of BFloat16 is the main focus of the following sections. Low precision data type BFloat16 has been natively supported on the 3rd Generation Xeon® Scalable Processors (aka Cooper Lake) with AVX512 instruction set and will be supported on the next generation of Intel® Xeon® Scalable Processors with Intel® Advanced Matrix Extensions (Intel® AMX) instruction set with further boosted performance. The Auto Mixed Precision for CPU backend has been enabled since PyTorch-1.10. At the same time, the support of Auto Mixed Precision with BFloat16 for CPU and BFloat16 optimization of operators has been massively enabled in Intel® Extension for PyTorch, and partially upstreamed to PyTorch master branch. Users can get better performance and user experience with IPEX Auto Mixed Precision. ## IPEX installation: IPEX release is following PyTorch, to install via pip: | PyTorch Version | IPEX version | | :---------------: | :----------: | | 2.0 | 2.0.0 | | 1.13 | 1.13.0 | | 1.12 | 1.12.300 | | 1.11 | 1.11.200 | | 1.10 | 1.10.100 | ``` pip install intel_extension_for_pytorch==<version_name> -f https://developer.intel.com/ipex-whl-stable-cpu ``` Check more approaches for [IPEX installation](https://intel.github.io/intel-extension-for-pytorch/cpu/latest/tutorials/installation.html). ## How It Works For Training optimization in CPU 🤗 Accelerate has integrated [IPEX](https://github.com/intel/intel-extension-for-pytorch), all you need to do is enabling it through the config. **Scenario 1**: Acceleration of No distributed CPU training Run <u>accelerate config</u> on your machine: ```bash $ accelerate config ----------------------------------------------------------------------------------------------------------------------------------------------------------- In which compute environment are you running? This machine ----------------------------------------------------------------------------------------------------------------------------------------------------------- Which type of machine are you using? No distributed training Do you want to run your training on CPU only (even if a GPU / Apple Silicon device is available)? [yes/NO]:yes Do you want to use Intel PyTorch Extension (IPEX) to speed up training on CPU? [yes/NO]:yes Do you wish to optimize your script with torch dynamo?[yes/NO]:NO Do you want to use DeepSpeed? [yes/NO]: NO ----------------------------------------------------------------------------------------------------------------------------------------------------------- Do you wish to use FP16 or BF16 (mixed precision)? bf16 ``` This will generate a config file that will be used automatically to properly set the default options when doing ```bash accelerate launch my_script.py --args_to_my_script ``` For instance, here is how you would run the NLP example `examples/nlp_example.py` (from the root of the repo) with IPEX enabled. default_config.yaml that is generated after `accelerate config` ```bash compute_environment: LOCAL_MACHINE distributed_type: 'NO' downcast_bf16: 'no' ipex_config: ipex: true machine_rank: 0 main_training_function: main mixed_precision: bf16 num_machines: 1 num_processes: 1 rdzv_backend: static same_network: true tpu_env: [] tpu_use_cluster: false tpu_use_sudo: false use_cpu: true ``` ```bash accelerate launch examples/nlp_example.py ``` **Scenario 2**: Acceleration of distributed CPU training we use Intel oneCCL for communication, combined with Intel® MPI library to deliver flexible, efficient, scalable cluster messaging on Intel® architecture. you could refer the [here](https://huggingface.co/docs/transformers/perf_train_cpu_many) for the installation guide Run <u>accelerate config</u> on your machine(node0): ```bash $ accelerate config ----------------------------------------------------------------------------------------------------------------------------------------------------------- In which compute environment are you running? This machine ----------------------------------------------------------------------------------------------------------------------------------------------------------- Which type of machine are you using? multi-CPU How many different machines will you use (use more than 1 for multi-node training)? [1]: 4 ----------------------------------------------------------------------------------------------------------------------------------------------------------- What is the rank of this machine? 0 What is the IP address of the machine that will host the main process? 36.112.23.24 What is the port you will use to communicate with the main process? 29500 Are all the machines on the same local network? Answer `no` if nodes are on the cloud and/or on different network hosts [YES/no]: yes Do you want to use Intel PyTorch Extension (IPEX) to speed up training on CPU? [yes/NO]:yes Do you want accelerate to launch mpirun? [yes/NO]: yes Please enter the path to the hostfile to use with mpirun [~/hostfile]: ~/hostfile Enter the number of oneCCL worker threads [1]: 1 Do you wish to optimize your script with torch dynamo?[yes/NO]:NO How many processes should be used for distributed training? [1]:16 ----------------------------------------------------------------------------------------------------------------------------------------------------------- Do you wish to use FP16 or BF16 (mixed precision)? bf16 ``` For instance, here is how you would run the NLP example `examples/nlp_example.py` (from the root of the repo) with IPEX enabled for distributed CPU training. default_config.yaml that is generated after `accelerate config` ```bash compute_environment: LOCAL_MACHINE distributed_type: MULTI_CPU downcast_bf16: 'no' ipex_config: ipex: true machine_rank: 0 main_process_ip: 36.112.23.24 main_process_port: 29500 main_training_function: main mixed_precision: bf16 mpirun_config: mpirun_ccl: '1' mpirun_hostfile: /home/user/hostfile num_machines: 4 num_processes: 16 rdzv_backend: static same_network: true tpu_env: [] tpu_use_cluster: false tpu_use_sudo: false use_cpu: true ``` Set following env and using intel MPI to launch the training In node0, you need to create a configuration file which contains the IP addresses of each node (for example hostfile) and pass that configuration file path as an argument. If you selected to have Accelerate launch `mpirun`, ensure that the location of your hostfile matches the path in the config. ```bash $ cat hostfile xxx.xxx.xxx.xxx #node0 ip xxx.xxx.xxx.xxx #node1 ip xxx.xxx.xxx.xxx #node2 ip xxx.xxx.xxx.xxx #node3 ip ``` When Accelerate is launching `mpirun`, source the oneCCL bindings setvars.sh to get your Intel MPI environment, and then run your script using `accelerate launch`. Note that the python script and environment needs to exist on all of the machines being used for multi-CPU training. ```bash oneccl_bindings_for_pytorch_path=$(python -c "from oneccl_bindings_for_pytorch import cwd; print(cwd)") source $oneccl_bindings_for_pytorch_path/env/setvars.sh accelerate launch examples/nlp_example.py ``` Otherwise, if you selected not to have Accelerate launch `mpirun`, run the following command in node0 and **16DDP** will be enabled in node0,node1,node2,node3 with BF16 mixed precision. When using this method, the python script, python environment, and accelerate config file need to be present on all of the machines used for multi-CPU training. ```bash oneccl_bindings_for_pytorch_path=$(python -c "from oneccl_bindings_for_pytorch import cwd; print(cwd)") source $oneccl_bindings_for_pytorch_path/env/setvars.sh export CCL_WORKER_COUNT=1 export MASTER_ADDR=xxx.xxx.xxx.xxx #node0 ip export CCL_ATL_TRANSPORT=ofi mpirun -f hostfile -n 16 -ppn 4 accelerate launch examples/nlp_example.py ``` ## Related Resources - [Project's github](https://github.com/intel/intel-extension-for-pytorch) - [API docs](https://intel.github.io/intel-extension-for-pytorch/cpu/latest/tutorials/api_doc.html) - [Tuning guide](https://intel.github.io/intel-extension-for-pytorch/cpu/latest/tutorials/performance_tuning/tuning_guide.html) - [Blogs & Publications](https://intel.github.io/intel-extension-for-pytorch/cpu/latest/tutorials/blogs_publications.html)
