Megatron-LM NVIDIA Megatron-LM 是一个基于 PyTorch 的分布式训练框架,用来训练基于Transformer的大型语言模型。Megatron-LM 综合应用了数据并行(Data Parallelism),张量并行(Tensor Parallelism)和流水线并行(Pipeline Parallelism)。很多大模型的训练过程都采用它,例如bloom、opt、智源等。 torch.distributed(dist) 为运行...
Tensor parallelism takes place at the level ofnn.Modules; it partitions specific modules in the model across tensor parallel ranks. This is in addition to the existing partition of theset of modulesused in pipeline parallelism. When a module is partitioned through tensor parallelism, its for...
Hi, thanks! I use vllm to inference the llama-7B model on single gpu, and tensor-parallel on 2-gpus and 4-gpus, we found that it is 10 times faster than HF on a single GPU, but using tensor parallelism, there is no significant increase i...

on 8 GPUs from 10mn with regular PyTorch weights down to 45s. This really speeds up feedbacks loops when developing on the model. For instance you don't have to have separate copies of the weights when changing the distribution strategy (for instance Pipeline Parallelism vs Tensor Parallelism)...

This method allows you to leverage the GPU’s parallelism to convert the data to FP16. It also enables you to fuse this operation with common pre-processing operations such as normalization or mean subtraction. Generally speaking, you can improve performance considerably if you do not mix precisi...
Is a medium or large size and requires larger batch sizes for training during which high parallelism is beneficial. TPU The TPU is much closer to an ASIC, providing a limited number of math functions, primarily matrix processing, expressly intended for ML tasks. A TPU is noted for high throu...

Describe the bug I am training the LLM with DeepSpeed Pipeline Parallel (ZeRO0 or ZeRO1 used). But I have a tricky issue: Assuming global_batch_size=4, single machine with 8GPUS, and PP=8, so DP=1, and micro_batch_size=4. Further assumin...
