Open MPI Weekly Telcon

PMIx - PR3696
- IBM will open an issue associated with this.
- When PMIx fixed IBM Load/Store issue, opened a can of issue (memory corruption, alignment in PMIx Lib).
  - was hitting some hangs and data corruption.
  - Still iterating on. Once that's done, can PR it to v3.x
  - Ralph thinks he's got that running cleanly now.
- We want these changes inside of v3.0.
Cisco tests still having some weird issue in their MTT with
- Leave Session Attached is busted.
PMIx & SLURM
- in SLURM if you configure (default) you don't get PMIx support.
- in 3.0.x if you launch directly, they all throw an error in MPI_Init().
- Ralph will improve the error message when MPI_Init() can't find a PMIx server.
- Not a blocker, but nice to have.
Brian is working on Release Template, and will get v3.0 RC out this week.
Schedule for v3.0 is still end of this month.
Branch for next release will be End of Face to Face in July.
Expectations for Folks to test RC.
- Down the road we should make a release tarball each night, and have MTT test THAT nightly.
- Very different in how they're built, until they call 'make dist'.

Mellanox was having some MTT testing issue, Artem will look at it.
- Mellanox might be seeing it because of deprecated build status stuff.
Some issues with tests running successfully, but then hangs at the end of output, and dies due to Timeout.
Right Now PRs, building exactly what the person PRs,
- But could build AFTER a merge of the PR and test THAT.
- IBM has seen internally this method has caught a failure before it was merged to the branch.
- Amazon likes this approach also.
Have always allowed merging to Master without a PR, but trying to make it more attracted to PR.
Still test each commit to master, and also
ompi_scripts/Jenkins - all available, can make changes there.

Intel is pushing content somewhat regularly, but unclear how much longer.
- Not seeing much benefit.
Howard - Trying to use it an trying to work on viewer.
