likely to be optimised only for "common" architectures (e.g. no AVX512 on x86 - SSE only? - and no SVE on aarch64) Cheers, Gilles On Fri, Jan 31, 2025, 18:06 Marco Vogel wrote: Hello, I implemented a new OP component for OpenMPI targeting the RISC-V vector extension,

[OMPI devel] Question about auto-vectorization behavior for OpenMPI OP components across architectures

2025-01-31 Thread Marco Vogel
Hello, I implemented a new OP component for OpenMPI targeting the RISC-V vector extension, following existing implementations for x86 (AVX) and ARM (NEON). During testing, I aimed to reproduce results from a paper discussing the AVX512 OP component, which stated that OpenMPI’s default compile
