Kiangpeng Lau contributed to HabanaAI/optimum-habana-fork by building performance and scalability features for large language model training. He introduced a fused scaled dot product attention kernel for Gemma FP8 attention, integrating it into GaudiGemmaAttention to improve throughput and modularity on Gaudi hardware using PyTorch. He also enabled Fully Sharded Data Parallel (FSDP) support for the granite-3.1-8b-instruct model, adding dedicated configuration and test coverage to facilitate distributed training. Additionally, he addressed a critical pretraining save state bug in the Gemma2 model, simplifying initialization and improving reliability. His work demonstrated depth in model optimization and distributed systems.

Apr 1, 2025April 2025 performance summary for HabanaAI/optimum-habana-fork. Focus this month was on enabling scalable training for large models by introducing Fully Sharded Data Parallel (FSDP) support for the granite-3.1-8b-instruct model in the testing environment. A dedicated FSDP configuration file was added along with updates to the test suite to validate the FSDP path, laying the groundwork for future optimization of memory usage and compute efficiency. Commit referenced: a98ce97247b6d6c812f469b8a3db07f6f0b277ed (Add FSDP config for Granite model (#1897)). No major bugs were closed this month; instead, the focus was on enabling scalable experimentation and improving testing reliability. Overall impact includes faster iteration cycles for large-model experiments, potential cost savings through better resource utilization, and strengthened configuration management for distributed training. Technologies/skills demonstrated include PyTorch FSDP, distributed training configuration, test automation, and repository configuration management.

Nov 1, 2024November 2024 performance-focused month for HabanaAI/optimum-habana-fork. Delivered a targeted optimization of Gemma FP8 attention through a fused SDPA kernel (ModuleFusedSDPA) integrated into GaudiGemmaAttention, and fixed a critical FP8 flash_attention throughput regression. The changes enhance Gaudi throughput, reduce latency, and lay groundwork for further FP8 optimizations. Key outcomes include improved modularity through a dedicated fused SDPA component and a clearer path to hardware-specific optimizations.
