What does this PR do?
TorchTensorParallelPlugin
to support TP with Pytorch 2.0. This work should be seen along with the PR feat: add support for tensor parallel using Pytorch 2.0 transformers#34194.Please review in conjunction with huggingface/transformers#34194
Results
See significant improvement in both memory and throughput compared against single gpu training, and FSDP across different settings (checkpointing on/off) and context lengths.
Done on two models
Tables below show the max cuda memory and throughput for various configurations showing the potential of TP contributed in this PR. There is gains in both memory and throughput.
