Bring Slurm PMI-1 component online
Bring the s2 component online
Little cleanup - let the various PMIx modules set the process name during init, and then just raise it up to the ORTE level. Required as the different PMI environments all pass the jobid in different ways.
Bring the OMPI pubsub/pmi component online
Get comm_spawn working again
Ensure we always provide a cpuset, even if it is NULL
pmix/cray: adjust cray pmix component for pmix
Make changes so cray pmix can work within the integrated
ompi/pmix framework.
Bring singletons back online. Implement the comm_spawn operation using pmix - not tested yet
Cleanup comm_spawn - procs now starting, error in connect_accept
Complete integration
Portals4 supports atomic ops on datatypes less than or equal to
max_fetch_atomic_size bytes. This commit fixes a bug that required
the datatype to be less than max_fetch_atomic_size bytes.
- make the internal structure follow the Open MPI naming convention
- provide a single flag/macro which controls the compilation/utilization of this
feature, to avoid that somebody using this has to modify every single
fcoll component. A configure option could be added later if desired.
configury: fix hcoll, fca and mxm detection and revamp yalla Makefile.am
Thanks to David Shrader and Ake Sandgren for bringing this issue to our attention
* do not add -I/.../include/fca -I /.../include/fca_core to CPPFLAGS
* allow configure --with-fca
* search fca libs in both DIR/lib and DIR/lib64
* fix the description of the --with-fca option
* do not add -I/.../include/hcoll -I /.../include/hcoll/api to CPPFLAGS
* allow configure --with-hcoll
* search hcoll libs in both DIR/lib and DIR/lib64
* fix the description of the --with-hcoll option
mtl_ofi_provider_include (resp. mtl_ofi_provider_exclude) can be used
to specify which provider(s) the OFI MTL can select (resp. ignore).
e.g. --mca mtl_ofi_provider_include "psm,sockets"
By default, mtl_ofi_provider_exclude is set to "sockets,mxm".
This deprecates the old MCA var named "mtl_ofi_provider".
This commit does the following:
* s/ompi_check_treematch/ompi_topo_treematch/ (i.e., abide by the
prefix rule)
* change the value of ompi_topo_treematch_happy from yes/no to 0/1, so
that we can use -eq for numerical comparisons (vs. string
comparisons). It's the little things in life, no?
* Check the valueo f $OPAL_HAVE_HWLOC to ensure that hwloc support is
enabled. If not, disqualify treematch from building.
* Fixes a few places that were underquoted
* Convert from "test ... -a ..." to "test ... && test ..."

This commit rewrites parts of libnbc to fix issues identified by
coverity and myself. The changes are as follows:
- libnbc function would return invalid error codes (internal to
libnbc) to the mpi layer. These codes names are of the form
NBC_. They do not match up with the error codes expected by the mpi
layer. I purged the use of all these error codes with the exception
of NBC_OK and NBC_CONTINUE in progress. These codes are used to
identify when a request handle is complete.
- Handles and schedules were leaked by all collective routines on
error. A new routine was added to return a collective handle
(NBC_Return_handle).
- Temporary buffers containting in/out neighbors for neighborhood
collectives were always leaked.
- Neigborhood collectives contained code to handle MPI_IN_PLACE which
is never a valid input for the send or receive buffer. Stipped this
code out.
- Files were inconsistently named. Most are nbc_isomething.c but one
was named coll_libnbc_ireduce_scatter_block.c.
- Made the NBC_Schedule "structure" and object so it can be
retained/released. This may enable the use of schedule caching at a
later time. More testing will be needed to ensure the caching code
works. If it doesn't the code should be stripped out completely.
- Added code to simply common case of scheduling send/recv +
barrier.
- Code cleanup for readability.
The code now passes the clang static analyzer.

Some OFI providers such as "sockets" are used for debugging
purposes mostly. For these providers, other components usually
offer better performance -- e.g. for sockets, the BTL/TCP would
be a better choice.
Thus, we chose to ignore some providers unless explicitly asked
by the user on the command line:
e.g. --mca mtl_ofi_provider sockets
