Worked on the facebookresearch/faiss repository to deliver ROCm 7+ launch bounds compatibility, addressing a build-time issue caused by the deprecated __AMDGCN_WAVEFRONT_SIZE macro. The solution involved removing the deprecated macro and implementing a version-aware device-side launch-bounds calculation that delegates to rocprim for ROCm 7.x and newer, while preserving compatibility with older ROCm versions. This approach resolved compilation errors with amdclang++ and stabilized cross-version builds for FAISS on AMD GPUs. The work demonstrated proficiency in C++, CUDA, and GPU programming, and contributed to simplifying upgrade paths and reducing maintenance overhead for users deploying FAISS on diverse ROCm environments.

Apr 1, 2026Delivered ROCm 7+ launch bounds compatibility for FAISS in 2026-04 by removing the deprecated __AMDGCN_WAVEFRONT_SIZE macro and implementing a version-aware device-side launch-bounds calculation that delegates to rocprim for ROCm 7.x+. This preserves compatibility with older ROCm versions while enabling correct behavior on ROCm 7.x+, addressing a known build-time/deprecation issue. The change corresponds to PR #4619, merged after review (Reviewed By: mnorris11; Pulled By: subhadeepkaran) and pulls from the facebookresearch/faiss repository. Impact: simplifies upgrade paths for users running on ROCm 7+ GPUs, reduces maintenance burden, and stabilizes cross-version builds for FAISS on AMD hardware. Technologies/skills demonstrated: C++ device programming, ROCm/amdclang++, rocprim integration, macro deprecation handling, and open-source code review workflow.
