Open MPI Weekly Telecon

v2.1.4 - Targeting Oct 15th,
- Merged in a bunch of stuff.
- One-sided multithreaded bugs that came up.
  - Doesn't feel like it's worth it to fix in v2.1.x, so instead pulled configurey changes from v2.0 to v2.1.x
No new news on v2.1.x

v3.0.1 went out the door.
- Oops, Did not get PMIx Compatibility pieces in embedded PMIx
v3.0.2 open for bugfixes. Quick turnaround on this.
- Shooting for May 1st.
- Will pre-emptively fix PMIx compatibility pieces to pickup PMIx v1.2.5 clients.
- This will bring in PMIx compatibility with OMPI client (mpirun/orted/libmpi) from OMPI v2.1.3
memkind disable needs to get into v3.0.2, Either taken care of or waiting to be taken care of.
PR (fix ppc64-big-Endian) can't merger until 4563 is merged.
- Thought Nathan was going to fix the hang, and then merge.
- Given this is the same issue as ARM, where we don't have a block, thought we'd just remove
- We now understand the problem, and not a silent data corruption, just a hang.

Schedule - ASAP - but blockers keep getting filed.
- No one seems particularly eager to get it out.
- Not getting any
blockers
1. One is high level of failures in CISCO MTT. Pretty sure it's not unique to 3.1.x, and happening on v3.0.x
  - --plm_base_verbose only 'non-default' flag setting.
  - Under slurm with mpirun not direct launch.
  - Jeff still investigating.
2. UCX OSC is failiing in ibm tests on v3.1.x and on master. Geoff will post issue and @xin on it.
Not going to merge in PMIx patch, unless someone says they really want it. Would require a new RC.

OSHMEM v1.4 - not sure if we have to drop the depricated APIs, curious OMPI is dropping depricated APIs...
- Only remove things removed from the OSHMEM standard, not things Deprecated as "deprecated" means it will be removed from a future version of the standard. If some APIs were removed from the standard, then ask oshmem email list their thoughts.
