https://github.com/open-mpi/ompi/issues/6568 - put protocol has lost it's pipelining.
- Right now only shows in vader, because all others prefer get protocol.

Review Master Master Pull Requests
- PR6556 and 6621 should go to the release branches.
- no update
- Good reminder that we now need to be careful about OPAL's ABI.
- When do we get rid of 32bit?
- Still don't have any release manager.
- Need to identify someone in next few months.
- PMIx v3.1.3 is ready to release.
- put a tarball in ompi's v4.0.x for integrated test
- So far looking good.
- One issue on Mellanox CI, probably cluster, or test config
- PMIx v2.2 update could be ready soon after that.
- Doesn't have MPIR fix.
- Missing something else. - Ralph will audit.
- Take a look at Gile's PRRTE work. He may have done SOME of that. He should have done that all in PRRTE layer, maybe just some MPI layer work remains.
- PR6339 - he's closed, and re-opened a new branch to look at.
- Howard reviewed PR6339, and likes everything that Giles did, so abandoned his branch
- This is a good approach, and gets something running, but it's not complete
- Need people to react and do things.
- Fall Face to face is canceled due to lack of agenda
- PRTE transtion still requires dedicated discussion
- Might meet in New Mexico, University of Tennisee, or Dallas (IBM)
- Should make a meeting prep page
- Jeff will make doodle.
- Two days
- IBM has some new failures.
- Geoff will get some time to look at this week.
- AWS - Scale testing not sure of status of that.
