Old Business

  • MTT -

    • If you change your MTT to startup PRRTE at begining of session, and just use prun.
    • Can see times cut in half or more.
    • This is good, but also need to test mpirun wrapper.
    • Cisco is converting half of MPI installs to use prrte/prun
  • OMPI master submodule pointers setup to track PMIx and PRRTE master.

    • Jeff discussed an idea to have some integration with PRRTE that putting a string in a PRRTE PR would automatically open an Open-MPI PR to update the PRRTE submodule after that PRRTE PR is merged to PRRTE master.

PMIx Update

  • CI testing only tests build and did it run, but doesn't test HOW it ran.
