Open MPI Weekly Telcon

Tagged and released last week.
Tag Kerfuffle:
- It was originally tagged in the wrong place (in master).
- It was deleted, and recreated in the correct place.
- HAVE disallowed forced pushes on master. (Don't know if it applies to tags or not).
- Please delete your old repos and use a new one (with this new tag) to make things sane again.

We still have some ARM issue
- What does our distro-repackagers for example Fedora / Debian do?
- If distro repackagers see that 32bit isn't working, do they still release 64bit?
Still planning to ship v2.0.3 despite Pasha and Oreon's Issue 2643.
- pinged him a while ago, and no progress on this.
Current schedule is start RCs May 23rd.
- Need to update News and .so versions. Maybe May 24th.
There are a lot of issues on v2.0.x. We'd like to move these to either v2.1.x or v3.x Do we need to fix them in v2.0.x? or beyond?
- EVERYONE please review open v2.0.x Issues.
- Close them if it's already addressed.
- Move them if needed.

Someone commented on a Closed Issue 1162 - looks like we missed a 1.10 bugfix in 2.1.1
A bunch that still need reviews.
Issue 3442 - 32bit builds are busted, probably affects v2.1.x also.
- Could be exotic architecture issue, or possibly just our CMA glue isn't right. CMA seems to be masking the issue?

v3.x update to v3.0.x change send out an email this afternoon, another go this weekend.
- Will invalidate any PRs to the v3.x that are still open, so those will need to be re-PRed.
When we did v2.x we pulled out Checkpoint Restart out of master, and then remove it from v3.x/v3.0.x also.
- Brian will do this after the rename.
Schedule for v3.0.0
- We're behind.
- Not sure if we're ready for a CR when the runtime isn't ready.
PMIx update (via Josh as Ralph is out):
- PMIx team has agreed to release the current state of PMIx master as v2.0, and will release the cross-version support as v2.1 since it doesn't represent a change to the "standard". There is one more bug fix we want to get into it and then Ralph will roll the release candidate.

Amazon is not testing SuSE right now, but they are testing SLES.
Amazon is about to add ARM with Pasha (ARM). - isn't stock ARMv8, 64bit.
Amazon is trying to track down a testing failure, that they're seeing. Probably not the specific PR that failed, but mpirun hung.
Don't have a great way to bot:retest:ARM because of the way that Jenkins works.
- Don't stress about it too much, just :retest: all of the platforms.
Edgar - UH Platform should be back today.

Spectrum MPI customers asking for help on Open MPI mailing lists.
- IBM will identify the Spectrum mailing list and send customers there for support issues.
- Sorry for the confusion.
- this particular issue boiled down to an installation issue, or an IBM Pami PML specific issue.
- Community members graciously said not to worry about it, but to please have someone from IBM regularly monitor the mailing lists.
