OpenMPI/UCX/PMIx presentation

Q&A

  • Terje: Are the Intel compiler licenses becoming very expensive for people?
    • Mikael: paying similar price as before currently for 3y?
    • Simon: want to check, but info is in the office :-/
    • mostly paying for Intel Fortran + Intel MPI (worth it?)
    • Fortran compiler will be included in next Clang
    • we need to re-evaluate the Intel oneAPI beta releases?
  • would be interesting to leverage ReFrame for performance tests
    • and make it part of of uploaded test reports in easyconfig PRs
    • Victor: CSCS is working on regression suite using ReFrame + EasyBuild
    • major improvement in ReFrame 3.0 is making it easier to use other people's tests
