PROFILE
Chaojun Zhang
Over four months, contributed to the huggingface/optimum-habana repository by building and optimizing distributed deep learning workflows for Habana accelerators. Developed training performance improvements for models like OH CLIP and T5-large, leveraging PyTorch and torch.compile to accelerate throughput and enable dynamic, region-aware compilation via GaudiAccelerator. Enhanced deployment flexibility by introducing per-module optimization APIs and configuration options for memory management in Dynamo-driven workflows. Addressed a regional compilation regression for FLAN-T5, restoring model throughput on Habana devices. Work included Python-based implementation, CLI enhancements, and comprehensive documentation updates, resulting in more scalable, efficient, and reproducible large-model training pipelines for users.

Nov 1, 2024Month 2024-11: Delivered key training performance optimizations for OH CLIP in the huggingface/optimum-habana repo, introducing PyTorch compile-based acceleration and dynamic MPI compilation via GaudiAccelerator. Migrated OH CLIP (roberta-clip) training to torch.compile to improve throughput, and enabled dynamic compilation for MPI training, with accompanying tests and documentation updates to reflect the new workflow and compilation-based optimizations. This work reduces training time, enhances scalability, and lays a solid foundation for further Habana-based training optimizations and cost efficiency.
