Q&A

  • Bart has been looking into the OpenMPI + CUDA mess
    • alternative approach to Åke's PR #14919
    • could use CUDA as a build dependency to OpenMPI, but then we "break" the policy to only have FOSS in foss toolchain
    • alternative can be to include a small CUDA header file to build OpenMPI GPU-aware
    • also fixes the problematic case reported by Caspar (cfr. issue #14801)
    • some performance measurements were also done, shows that this approach introduces very little overhead
    • PR by Bart coming up soon...
