PROFILE
Wendy Liang
Wendy Liang contributed to the Xilinx/XRT repository by engineering robust HIP runtime features and cross-platform improvements over six months. She enhanced device management, memory handling, and error reporting, introducing per-thread HIP device selection, asynchronous memory prefetch, and comprehensive error APIs. Wendy refactored core components for thread safety and reliability, optimized kernel launch performance with caching, and improved build integration for downstream projects. Her work, primarily in C++ and Python, addressed low-level programming challenges, streamlined debugging, and ensured compatibility across Linux and Windows. These efforts resulted in a more stable, maintainable runtime that supports advanced HIP workflows and reliable deployment.

Sep 1, 2025September 2025 monthly review for Xilinx/XRT focusing on HIP platform improvements, stability, and build integration. Implemented robust HIP error handling with APIs to retrieve XRT exception information and hardware async errors, improved error reporting formatting, and laid groundwork for better debugging. Added control scratchpad buffer support for HIP kernel launches to enable advanced user workflows. Hardened the HIP runtime with device count argument fixes, removal of an unnecessary runs cache, and targeted fixes for correctness and static analysis, improving reliability. Enhanced build integration by propagating XRT include header directories to dependent projects for reliable header access when using XRT::xrt_hip. Overall, these changes boost debugging efficiency, runtime reliability, and downstream integration, delivering tangible business value for HIP-enabled workloads.

Jul 1, 2025July 2025: Delivered major HIP device management improvements, performance optimizations, and tracing enhancements for the Xilinx/XRT repository. Work spanned per-thread HIP device selection and memory handling, improved error handling for host memory flags, a thread-safe device context refactor, a HIP run-cache to reduce kernel launch overhead, and a new tracing/replay subsystem (xbtracer) using protobuf and Detours. A bug fix for stream/event lifecycle ensures correct event associations post-completion, contributing to stability and predictable scheduling. These changes collectively enhance stability, throughput, and observability while reducing runtime overhead.
