Open MPI Weekly Telecon

Schedule:
- Quick turnaround on this, Shooting for May 1st.
v3.0.2 open for bugfixes.
- 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.

- No one seems to have resources to fix this.

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.
