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.
When PtlMDBind was removed, the result check was left in which
causes intermittent failures depending on the junk value found in
the 'ret' variable. The commit removes the result check.
Due to user confusion, update the show-help messages displayed when
processor and/or memory binding fails. Thanks to Dave Love
(@loveshack) for the initial suggestion.

This script is useful to measure times from launching ompi
application to different internal points. A user can easy add
it`s test basing on existing tests.
See readme information inside the script.
Rename the pmix1xx component to pmix111 so it reflects the actual release it includes
Resolve the problem of PMIx being passed a bogus --with-platform argument when configuring the PMIx tarball code. There is no reason we should be passing --with-platform arguments to any internal subdirectory, so just leave that out when constructing the opal_subdir_args variable.
Update the PMIx code and continue attempting to debug direct modex
Fix a problem in the ORTE PMIx server - there was an early intent to optimize the direct modex by fetching data for all procs from the target job on the remote node, instead of fetching the data one proc at a time. However, this was never completely implemented, and so we would hang if we had multiple overlapping requests for data from more than one proc on the node.
Update PMIx to v1.1.2
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.
This commit removes a check that causes mca_base_group_register to
improperly create a new group instead of using an existing group
when the project and framework names are the same. This check was
originally intended to prevent forming groups with names like
ompi_ompi, opal_opal, etc but there is no reason why we shouldn't
allow that.

Mofed 2.2 does not have the IBV_EXP_QP_INIT_ATTR_ATOMICS_ARG attribute
flag. Add a check to fix compilation for mofed 2.2. This commit only
fixes complilation with the older mofed. It will not allow an Open MPI
compiled with mofed 2.3 or newer to work on a machine with mofed 2.2.

Cray has added plugins to slurm to support
the Cray programming env (alpslli, cray pmi, etc).
Some of the workarounds needed with plm/alps
to avoid issues with Cray PMI getting mixed up
with orte launch system are also required in
a cray native slurm environment.

There was a bug with the way the cray pmix component
was setting the locality property for ranks on the
same node, etc.
Improve location/syntax of a comment block.

If btl-portals4 is configured to use logical mapping of ranks to
physical nodes, then the endpoint must have the rank field set.
This commit fixes a bug that caused the endpoint to have the
nid/pid instead of the rank if the endpoint already exists.
`MPI_WIN_TEST` must update the `flag` parameter to 0 when not all
origin processes called `MPI_WIN_COMPLETE`. But sm OSC doesn't.
If the caller initialize the `flag` argument to a non-0 value,
the caller will receive the non-0 `flag` value.
