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

  • PRRTE Transition:

  • OMPI master submodule pointers setup to track PMIx and PRRTE master.

    • Hopefully long term, master can track release branches.
    • But still ensure there's some regression tracking of master/master/master.
    • But once things settle down, might not want everyone's masters tracking each other.
    • But if we DONT have master/master/master then new features that span across repos will be challenging

Release Branches

Blockers All Open Blockers

Review v3.0.x Milestones v3.0.6

Review v3.1.x Milestones v3.1.6

  • Michael is interested in a schedule.
    • He will discuss and propose a date

Review v4.0.x Milestones v4.0.3

  • v4.0.3 in the works.
    • Config file needs to be committed to
    • Merging in PRs
    • Seeing some instability on github right now.

v5.0.0

  • Schedule:
    • Feature Freeze: End of April
    • Release: End of June
  • Austen took an initial stab at issues and is starting a google sheets of v5.0 features.
  • Issue - 7475 Blocker for Amazon.
    • When marking items as blockers, please add rational.
    • This is functionality is in v4.0, and if you don't specify a PML you'd get this modex.
    • Apparently the check wasn't working in 3.0 or 4.0
  • May need doc updates for command line changes, both prrte, and mca changes.
    • Want to get some feedback some community.
    • Huge list of features

master

  • Biggest thing on master is prrte.
    • Issues are being found and fixed.
  • Cisco mtt failing due to -np

Face to face

  • Maybe mid-late summer. No discussion

Infrastrastructure

  • scale-testing, PRs have to opt-into it.

Review Master Master Pull Requests

CI status

Depdendancies

PMIx Update

  • CI testing only tests build and did it run, but doesn't test HOW it ran.
    • Environment setup can be a bit different.
    • For example no-permissions in /tmp. Might pass on one machine, and fail on another without /tmp permissions.
