LLVM Clang Shows Off Great Performance Advantage On NVIDIA GH200's Neoverse-V2 Cores

Mon, 03/18/2024 - 23:20
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.
