Open MPI Weekly Telcon

v2.1.3 (unscheduled, but probably jan 19, 2018)
- PR4172 - a mix between feature / bugfix.
Are we going to do anything for v2.x for hwloc 2?
- At least put in a configure error if detects hwloc v2.x
Still some PRs going in.
Not paying attention here, but will have a callback

Ralph did some more investigation, and found that dstore backwards compatibility would work with OMPI v3.0, just not OMPI v2.0 stream
- This revelation meets Open MPI's backwards compatibility commitments.
- Need to start testing v3.1 in MTT.
v3.1.x -
- DONE - Roll hwloc back to 1.11.7 on v3.1.x branch (Ralph put together, Brian reviews)
Schedule - No point in rolling RC until more people turn on v3.1 testing.
- Outlook - Probably will not get out by supercomputing. :(
Brian will send out requests to start testing v3.1
Add v3.1 to MTT tests
- Database is active now to accept v3.1 tests.
- MTT disk full issue has been resolved.

Master version is currently v4.0, but that's an artifact of the datatype stuff that ended up getting pulled into v3.0, so it can be made to be v3.2
Cisco and possibly others will begin testing v3.1 depsite v2.x not quite being out.
Many failures at Cisco due to lack of --oversubscribe flag with MPI_Spawn

Website - openmpi.org
- Brian trying to make things more automated, so can checkout repo, etc. Repo is TOO large.
- Majority of the problem is the Tarballs. and already storing those in S3.

Allinia - Debugger attach on v2.x - Issue 3660
Request they retest with new version - Issue 3384
Need to see if Attributes are MT - IBM will see if we have any tests to audit.
- Asked, need to get answer back from them.
