- PR6844 - Want to test if this affects containers.
- Worth the question, don't see any reason not to take this.
- Jeff will review and add comments.
- Howard will do some testing and talk to Charlie-cloud.
- No update (Brian on vacation)
- Merged
--recurse-submodulesupdate intoompi-scriptsJenkins script as first step. Let's see if that works.
Blockers All Open Blockers
Review v3.0.x Milestones v3.0.4
- No new news
Review v3.1.x Milestones v3.1.4
- PR6556 and PR 6621 should go to the v3.x release branches.
- No new news
Review v4.0.x Milestones v4.0.2
-
Still have some issues; we expect to still have to do an rc2, e.g., https://github.com/open-mpi/ompi/issues/6932.

Discuss Issue 6568 - large messages overwhelm put
- This SHOULD stay as a blocker, since it ends in hang.
- We need to look for a workaround.
- Could disable put completely.
- Could use an opal_unlikely check of message-size, and only then kick it back if the message size is too large.
- OB1 tries put / get, and if these don't work, it falls back to send/recv.?
- possibly a flaw in put itself.
- Jeff will ask george what would be viable workaround, and identify.
- Not signing up to implement.
-
PR6942 - ready to merge.
-
https://github.com/open-mpi/ompi/issues/6949 - Geoff (and others please review)

MTT failures in Generic Simple unpack on v4.0.x - segfaults, assertions.
- DDT-unpack assertion on v4.0.x
Review Master Master Pull Requests
- IBM's PGI test has NEVER worked. Is it a real issue or local to IBM.
- nVidia bought PGI, perhaps someone there could take a look?
- Akshay said he'd talk to a PGI person at nVidia to see.
- Edgar mentioned that Mark Allen should rebase PR6756 and get that in to resolve an issue another customer is seeing.
- Cray running into problems again. :frown:
- Back on track.

- IBM has to triage some failures on master and v4.0.x and some test build issues. Josh Hursey thought they might be accidentally mixing XLC and PGI compilers. Will investigate.
- Cisco has a build failure to investigate.
