Agenda

Review 1.10

• Milestones: https://github.com/open-mpi/ompi-release/milestones/v1.10.3
• 1.10.3 has been released June 15th.
• Would like to start transitioning folks to use 2.0.0 as soon as we release.

Review 2.0.x

• Wiki: https://github.com/open-mpi/ompi/wiki/Releasev20

• Blocker Issues: https://github.com/open-mpi/ompi/issues?utf8=%E2%9C%93&q=is%3Aopen+milestone%3Av2.0.0+label%3Ablocker

• Milestones: https://github.com/open-mpi/ompi-release/milestones/v2.0.0

• Master PR1817 - does this need to go to 2.0.0 or 2.0.1?

  • Master PR that Pasha @ Mellanox says needs to go to v2.x
  • need more info about reproducer of bug this fixes. Maybe UCX / Add procs non-default issue?

• v2.x PR1246 - cherry pick of MPI_Request Multi-thread race condition. Hope to get in tonight.

• Last week still waiting on:

  • PR1237 on ompi-release - PR1794 and PR1795
  • and Jenkin's failure on Mellanox cluster.
    • thread_test 1.1 - running overlap test. Not great, but good at finding bugs.

• PR1821 - additional performance improvements for MPI_Waitsome() Not regression.

  • George and Nathan need to look at.

• If we get PR1821 and PR1246

  • Roll RC4 tomorrow, and diagnose Mellanox issue.
  • if we could release next Tuesday, that would be fantastic!

New Items

• Andrew Lumsdaine, our primary faculty sponsor for Open MPI at Indiana University, is leaving IU.

  • We have a bunch of Open MPI infrastructure hosted at IU (for free): the web site, MTT web reporter + database, ...etc. This infrastructure is now likely to go away within the next several months.
  • There are many implications of such a move: cost, features, resources, timing, ...etc. We need to start talking about this as a community to decide: a) where to move OMPI's electronic infrastructure, and b) how to move it (there are complicated technical issues involved).
  • Ralph, Howard, and I have been looking at alternatives over the past few days. We would like to present a few ideas / proposals to everyone.
  • We have approximately 3 month deadline to find new home.
    • web services at IU (website, mailinglist archives, nightly tarballs).
    • MTT web + MYSQL needed also.
    • Building of nightly tarballs, and release tarballs.
    • Github automation - bots, other minor. Some is webbased, some is script / cron based.
    • Jenkins would go away.
  • Jeff and Howard has Google doc, will transition to Wiki
  • IU also is holder of legal docs. All data is now electronic, so should be okay to archive in a community space.

• Please go fill out doodle for Summer Meeting: (https://github.com/open-mpi/ompi/wiki/Summer-2016%2CTBD)

  • Right now looks like 2nd week of August.
