PROFILE

Jinghan Yao

Yao delivered the Flash-Partitioned Distributed Transformer (FPDT) feature for the deepspeedai/DeepSpeed repository, focusing on enabling sequence-parallelism for large language models through CPU-offloaded attention and feedforward networks. Using Python and CUDA, Yao partitioned attention computations across sequence-parallel ranks, which improved both memory efficiency and training performance. The work included updating activation checkpointing to further reduce memory usage and increase throughput during model training and inference. Additionally, Yao implemented a new CI workflow to validate flash attention, enhancing reliability and feedback speed. This contribution demonstrated depth in distributed systems, deep learning, and transformer architecture within a complex codebase.
