PROFILE
Antoine Viallon
Worked on backend stability and GPU compatibility for the llama.cpp repository, focusing on reliability and hardware support. Addressed a critical divide-by-zero issue in server metrics reporting by introducing defensive programming techniques in C++, ensuring stable metrics calculations and preventing crashes under edge conditions. Later, improved GPU readiness for MI210 hardware by correcting the CDNA2 compute capability constant in the ggml-cuda module, aligning it with the gfx90a ISA to reduce kernel misconfiguration risks. Demonstrated expertise in C++, CUDA, and performance optimization, with a disciplined approach to root-cause analysis and precise version control, resulting in more robust production deployments.

Apr 1, 2026April 2026: Stabilized GPU compatibility and readiness for MI210 on llama.cpp ggml-cuda by correcting the CDNA2 compute capability constant to reflect gfx90a ISA (0x90a). The fix reduces kernel misconfiguration risks and improves performance stability on CDNA2 hardware. This month focused on resilience and hardware-ABI correctness, enabling smoother enterprise deployment on AMD GPUs.
