PROFILE

Pengzhan Zhao

Worked on feature development for GPU programming and compiler infrastructure, focusing on memory and performance optimization. In the fzyzcjy/triton repository, delivered TDM store support for the AMD gfx1250 architecture by implementing asynchronous local-to-global copies in Gluon IR, updating the TDM language and MLIR conversion, and validating the end-to-end integration. Later, in intel/intel-xpu-backend-for-triton, optimized storage for the MXFP FA example by introducing a two-stage write flow using Local Data Store and TDM store, improving cache locality and throughput. Utilized C++, MLIR, and Python to address low-level memory management challenges and enable higher-performance inference workloads.

March 2026: Delivered MXFP FA Example Storage Optimization in intel/intel-xpu-backend-for-triton by replacing the buffer_store path with a two-stage write flow (LDS first, then TDM store). This change improves cache efficiency and read/write throughput by enabling earlier data residency and better memory access patterns. Adjusted layout handling and memory allocation to support the new storage method. All changes are scoped to the MXFP FA example in the Triton backend and are captured in the referenced commit set.

October 2025: Delivered TDM store support on gfx1250 AMD GPU architecture in Triton. Implemented asynchronous local-to-global TDM copies in Gluon IR, enabling store operations and related tests. Updated the TDM language and MLIR conversion to support the new store functionality. Added test coverage around the new store path and validated end-to-end flow. No major defects reported; focused on feature delivery and laying groundwork for higher memory-throughput workloads on gfx1250.
