Agenda

Review All Open Blockers

  • Discuss Progression Issue 3616
    • openib progression issue.
    • Nathan will try to look at this, this week.
    • Not sure where we might block in the callbacks.
    • George is re-working progression model, but because we're getting new model, we just need an ugly solution for now.
    • Hit this in a non-contiguous one-sided put down in openib via osc_rdma. The accumulate wants to trigger another callback. And then a barrier to get the timing right.
    • Nathan thinks he can make the unlock non-blocking in the accumulate lock.

2.0.3

  • released June 1st.
  • No driver for a v2.0.4 at this time.

Review v2.x

  • v2.1.1 went out in May
  • No Driver for v2.1.2 at this time.

Review Milestones v3.0

  • Planning to do v3.0 RC today, but lots of failures in nightly MTTs.
    • Cisco killed a bunch, and will re-kick-off a bunch.
  • Datatype and Info Key type errors out of IBM tests.
  • Amazon false positives because they're direct launching, but don't support dynamic processes in direct launch.
  • Howard sent out request for NEWs updates.
  • One additional PMIx issue.
    • orte, opal and PMIx, threading issue from IBM.
    • Some confusion if we have assembly backwards in PMIx 2.0 (Nathan or George)
    • Nathan can take a look when he gets into office today.
    • only seen evidence in PMIx.
    • Issue is in PMIx: https://github.com/pmix/pmix/issues/347
  • Ralph sync up with Brian and Howard end of day to hear status of issue, for v3.0 RC.

Review Master Pull Requests

Review Master MTT testing

  • Still seeing some 'make check' errors has been fixed.

  • 32bit compiler stuff fixed in pmix fix.
  • Geoffroy Vallee - still seeing some problems disabling make check.
  • MPI_Send_receive_replace - got fixed.
  • Timeouts are all CUDA related - nvidia.
    • still there.
  • Issue: Redhat stock autoconf (rather than build our own)
  • Need a maintainer for rankfile mapper.
    • IBM will take up maintaining rankfile mapper from Ralph.

MTT Dev status:

  • Intel making lots of progress. Nice features, but not sure how to make the transition.
  • .ini files would need to be transitioned across because python doesn't support funclets.
  • Does everyone have to transition the same day, or can the transition be one by one.
    • Yes, everyone can transition in their own time.
