Florent, Long story short, yes, this is a known limitation. btl/sm cannot be used for intra-nodes communications between processes from different "jobs" (MPI_Comm_spawn() creates a new job), so you will use the interconnect (if it allows it) or btl/tcp (assuming pml/ob1 had been selected). IIRC,

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

Gilles, Thank you for your response. I understand that distro-provided OpenMPI binaries are typically built for broad compatibility, often targeting only baseline instruction sets. For x86, this makes sense—if OpenMPI is compiled with a target instruction set like `x86-64-v2` (no AVX), the `

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

Marco, The compiler may vectorize if generating code optimised for a given platform. A distro provided Open MPI is 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: >
