During October 2024, Benoit Cornillon enhanced the GPU architecture specifications documentation in the ROCm/ROCm repository, focusing on improving clarity and consistency. He added detailed definitions for the Accelerator Complex Die (XCD) to the gpu-arch-specs table and clarified how numerical values correspond to both XCDs and GCDs, reducing ambiguity for future contributors. Working primarily with reStructuredText (RST) and leveraging his documentation skills, Benoit ensured that all updates aligned with ROCm’s documentation standards. The work was delivered through a traceable commit, reflecting a focused and well-scoped contribution that improved the maintainability and usability of technical documentation for GPU architectures.
