Review 1.10

  • 1.10.x
    • Still no drivers for a 1.10.5.

Review 2.0.x

  • Wiki

    • #2234 COMM_SPAWN broken: status?
      • Perhaps the problem is in the MPI layer...? Not really sure that it's in the PMIx layer.
      • Need someone to look at the MPI layer.
      • @hjelmn mentions that we re-wrote a bunch of comm CID stuff on master and brought it to v2.1.
      • Ralph confirmed: v2.1 and v2.0 both failing COMM_SPAWN
        • Ralph looks: PMIx between the two are identical.
        • Nathan marked 2215 a blocker -- it's the CID rewrite stuff.
        • Jeff will check out this PR and try it out to see if it fixes the problem.
        • If this fixes the problem, Nathan thinks it might not be hard to port this to v2.0.x.
        • Side effect: fixing scaling of COMM_SPLIT_TYPE. Yay!
      • Report from Orion P: we need to fix COMM_SPAWN for v2.0.x
    • #1831: Communication rate degradation: status?
      • Arm's graph doesn't show 2.0.x results. Will have to ask.
    • C++ compile error -- missing a PR from master (remove useless / duplicate commit). It's on v2.1.
      • Missing this commit on v2.0.x: c530b0a07c79e40eccf054bfc29260fcf93f54df
      • Jeff will file a PR for this.
    • v2.0.2 schedule:
      • Close bugs this Friday, Oct 28
      • Aim to release Fri Nov 4
  • Milestones

    • 2.1.0
      • PMIx 1.2.0: status?
        • PR 2286: will update to PMIx v1.2.0rc1. Testing is looking good. Two outstanding issues -- both should be done this week:
          • Update to Get
          • One thing Boris is working on.
        • Estimate release PMIx v1.2.0 this time next week.
        • People please try it out!
      • Yoda BTL fixes: status?
        • Boris has been doing some testing. Just finding a fragmentation issue so far -- should be a 1-line change. Working on it, but should be able to open a PR soon.
  • Master dev

    • PR #2285: enabling orte to use libfabric
