Agenda

Review 1.10

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
    • Patcher differences - PR1237 (missing commits) and request stuff.
      • Travis failed, but looks internal to travis. Jeff kicked it.
  • Milestones: https://github.com/open-mpi/ompi-release/milestones/v2.0.0
    • Open PR to fix Sparse Groups - Moved to 2.1.
  • Found some missing Master commits needed for 2.x:
    • PR1794 and PR1795 needs to be merged to 2.x - merging right away.
    • Master PR1804 - Nathan closed because he'd already done it, and not needed in v2.x
    • Heterogeneous builds broken - listed as a 2.0.0 - Think this is solved
      • Master Issue 1694 - v2.0.0 is good to go. Can be fixed in 2.0.1
    • https://github.com/open-mpi/ompi/milestones/v2.0.0
      • Can all of this be pushed to 2.0.1 or later?
      • Went through list of these on call, and looks like most can be closed or pushed to future.
  • So 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.
    • Nysal brought up MACRO issue with new request work that is deciding usage of mutexs and atomics based on how it was build, not param passed into MPI_Init.
      • OPAL_ENABLE_MULTITHREADS - for v2.x (only) OMPI_ENABLE_THREAD_MULTIPLE (specific to OMPI layer)
      • Nysal will get everything in tonight.
    • Roll RC4 tomorrow, and diagnose Mellanox issue.
    • if we could release next Tuesday, that would be fantastic!

New Items

  • Jeff: Contributor agreement for Broadcom received.
  • Jeff+Nathan: Idea for new (Linux) memory component: mlockall(MCL_FUTURE) (idea from "Alex A. Granovsky" and "Audet, Martin" on users list)
    • On users mailling list - mlockall - any time I add memory to process, lock it. Size of process will never shrink.
      • seems like a trivial thing to add to a new patcher component.
  • 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.
