Per feedback from rhc, manually set the base_ptr member
of the opal_buffer_t variable to NULL prior to calling
OBJ_RELEASE. A similar feature of opal_dss.load also
exists so likewise reset the base_ptr to NULL prior to
invoking it.
Hopefully the opal_buffer_t struct does not change
frequently.
Minor cleanups to reduce output when pmix_base_verbose
mca paramater is set.
usnic_fls() can actually return 0, leading us to incorrectly free() a
buffer instead of OMPI_FREE_LIST_RETURN_MT'ing it.
So add an explicit bool in the struct that tracks whether the buffer
came from malloc or a freelist.
This was CID 1269660.
Coverity alerted us to the fact that there are places where
the synonym_for param is hard-coded to -1 when calling
register_variable(). It would be a coding error if synonym_for==-1
and (flags & MCA_BASE_VAR_FLAG_SYNONYM)>0, so let's add that to the
debug-only check at the top of the function.
This was CID 993717.
Remove use of the Cray PMI KVS - which is designed for a lighweight
MPI that exchanges only a minimimal amount of connection info
(about 128 bytes per rank) - within cray/pmix. Use Cray PMI
collective extensions instead.
This is the first of several steps to accelerate launch of
Open MPI on Cray systems using either native aprun or nativized
slurm.
in this code and it ended up changing the logic that is used to set up eager RDMA.
Rather than setting up eager RDMA with a high priority message, it did it the other
way around. For some reason, CUDA-aware support did not like this. So, basically,
restore the logic to the way it was prior to the refactoring. The refactoring did not
intend to change this. Lightly reviewed by hjelmn.
Per open-mpi/ompi#381, convert the specific intialization of opal_pmix
to use the generic "= { 0 }" initializer. This form can be used to
initialize any type when the intent is just to zero out / assign
*some* value.
Embedding libfabric is a temporary measure; I'm removing some warning
notifications so that the output isn't so cluttered (we're getting
the real warnings fixed upstream, but the OMPI community doesn't
really care/need to see the warnings in the meantime).
This commit adds an MCA variable to select Portals4 logical
addressing, populates the logical-to-physical mapping table and
initializes the NI in this mode.
