and Efficiency + +## Overview + +The benchmark includes our efforts in using Colossal-AI to train different tasks to achieve SOTA results. +We are interested in both validataion accuracy and training speed, and prefer larger batch size to take advantage of more GPU devices. +For example, we trained vision transformer with batch size 512 on CIFAR10 and 4096 on ImageNet1k, which are basically not used in existing works. +Some of the results in the benchmark trained with 8x A100 are shown below. + +| Task | Model | Training Time | Top-1 Accuracy | +| ---------- | ------------ | ------------- | -------------- | +| CIFAR10 | [ViT-Lite-7/4](https://arxiv.org/pdf/2104.05704.pdf) | ~ 16 min | ~ 90.5% | +| ImageNet1k | ViT-S/16 | ~ 16.5 h | ~ 74.5% | + +The `train.py` script in each task runs training with the specific configuration script in `configs/` for different parallelisms. +Supported parallelisms include data parallel only (ends with `vanilla`), 1D (ends with `1d`), 2D (ends with `2d`), 2.5D (ends with `2p5d`), 3D (ends with `3d`). + +Each configuration scripts basically includes the following elements, taking ImageNet1k task as example: +``` +TOTAL_BATCH_SIZE = 4096 +LEARNING_RATE = 3e-3 +WEIGHT_DECAY = 0.3 + +NUM_EPOCHS = 300 +WARMUP_EPOCHS = 32 + +# data parallel only +TENSOR_PARALLEL_SIZE = 1 +TENSOR_PARALLEL_MODE = None + +# parallelism setting +parallel =

gradient update + +BATCH_SIZE = TOTAL_BATCH_SIZE // gradient_accumulation # actual batch size for dataloader + +clip_grad_norm = 1.0 # clip gradient with norm 1.0 +``` +Upper case elements are basically what `train.py` needs, and lower case elements are what Colossal-AI needs to initialize the training. + +## Usage + +To start training, use the following command to run each worker: +``` +$ DATA=/path/to/dataset python train.py --world_size=WORLD_SIZE \ + --rank=RANK \ + --local_rank=LOCAL_RANK \ + --host=MASTER_IP_ADDRESS \ + --port=MASTER_PORT \ + --config=CONFIG_FILE +``` +It is also recommended to start training with `torchrun` as: +``` +$ DATA=/path/to/dataset torchrun --nproc_per_node=NUM_GPUS_PER_NODE \ + --nnodes=NUM_NODES \ + --node_rank=NODE_RANK \ + --master_addr=MASTER_IP_ADDRESS \ + --master_port=MASTER_PORT \ + train.py --config=CONFIG_FILE +``` \ No newline at end of file diff --git a/benchmark/cifar/configs/vit_1d.py
