Update the configure logic for the new pmix120 component
ckpt
Get the pmix120 component to work - still not really registering or handling notifications, but infrastructure now operates
Cleanup some of the symbol scopes, and provide a more comprehensive rename.h file. Will pretty it up later - let's see how this works
Cleanup the rename files to use the pretty macros
When mtl-portals4 is configured for logical mapping, coll-portals4
must disqualify because it does not yet support logical mapping.
coll-portals4 looks for the endpoint pid to be zero which tells it
that mtl-portals4 is configured for logical mapping. This commit
initializes the endpoint nid/pid to zero for logical mapping.
Since OS X 10.11 (aka El Capitan) DYLD_LIBRARY_PATH is no more
propagated to children, so try to dlopen libmpi with the full path
using the directory of libmpi_java

Thanks Alexander Daryin for reporting this
NOTE: Building with external pmix *requires* that you also build with external libevent and hwloc libraries. Detect this at configure and error out with large message if this requirement is violated.
Closes#1204 (replaces it)
Fixes#1064
A previous commit updated the one-sided code to register the state
region only once. This created an issue when using the scratch lock
with fetching atomics. In this case on any rank that isn't local rank
0 the module->state_handle is NULL. This commit fixes the issue by
removing the scratch lock and using a fragment pointer instead.

accelerate message queue lookups if the lookups have
the proper tag&mask layout. OpenMPI should follow
PSM2's preferred tag&mask spec, so that PSM2 can provide
a performance benefit.
Remove send of the extra message. This bug hase triggered on
MPICH/coll/nbicbarrier test. In this test a series of communicators
are created.
This extre-message was reseived after original communicator was destroyed
and queued into non_existing_communicator_pending. When new completely
unrelated communicator with the same id as original was created this message
was pushed into the frags_cant_match queue and caused seq numbers skew and hang.
Remove excessive parameter check to avoid premature exit from the collective.
MPI standard says:
The type signature associated with sendcount, sendtype, at a process must be equal to
the type signature associated with recvcount, recvtype at any other process. This implies
that the amount of data sent must be equal to the amount of data received, pairwise between
every pair of processes.
In case of inter-communicator we have 2 group of processes and "left" group may call
MPI_Alltoall(NULL, 0, MPI_INT, buf, 10, MPI_INT, comm, ...);
and the right one:
MPI_Alltoall(buf,10,MPI_INT, NULL, 0, MPI_INT, comm, ...);
And it would be legal though one of the group will receive 0 bytes from others.
This was triggered by MPICH/coll test called icalltoall.
