With my recent NVIDIA GH200 Grace CPU benchmarks carried out remotely via GPTshop.ai, besides looking at areas like the 64K kernel page size performance benefits I also ran some fresh benchmarks looking at the performance difference when the binaries were generated by LLVM Clang rather than the default GCC compiler on Ubuntu Linux. This article shows off the performance difference for the 72-core Neoverse-V2 server/HPC processor when leveraging LLVM Clang rather than the GNU Compiler Collection.

For over a week—from February 21 to 29, 2024—nine teams of computational scientists and Earth system science researchers came together to hack their code, build their software development skills, and improve their projects. In the process, participants experienced the real-life benefits of practicing Open Science.

The GCC 14.1 stable compiler release due out in the coming months will now have initial working support for both AMD RDNA2 (GFX10.3) and RDNA3 (GFX11) graphics processors. This is intended for OpenMP and OpenACC offloading to the GPUs.
