the OPAL and ORTE libraries. This is required by projects such as ORCM
that have their own ORTE and OPAL libraries in order to avoid library
confusion. By renaming their version of the libraries, the OMPI
applications can correctly dynamically load the correct one for their
build."
This reverts commit 63f619f8719fb853d76130d667f228b0a523bd60.
This commit makes the folowing changes:
- Add support for the knem single-copy mechanism. Initially vader will only
support the synchronous copy mode. Asynchronous copy support may be added
int the future.
- Improve Linux cross memory attach (CMA) when using restrictive ptrace
settings. This will allow Open MPI to use CMA without modifying the system
settings to support ptrace attach (see /etc/sysctl.d/10-ptrace.conf).
- Allow runtime selection of the single copy mechanism. The default behavior
is to use the best available. The priority list of single-copy mehanisms is
as follows: xpmem, cma, and knem.
- Allow disabling support for kernel-assisted single copy.
- Some tuning and bug fixes.
Add MPI_Ibarrier.3in to reference MPI_Barrier.3, and update
MPI_Barrier.3in to include bindings for MPI_Ibarrier. Slightly update
the text to be inclusive of the non-blocking case.
Fixes#242.
Force completion of all puts before deregestering memheap/bss memory
Fixes a possible race condition where put request completion callback
is called when request context is already cleared.

Restore the functionality to error out (and show a helpful message) if
knem support is requested by is either not compiled in or cannot be
activated.
Thanks to Gus Correa for bringing the matter to our attention.
Somehow, this MCA param was accidentally dropped after v1.6.5. Thanks
to Gus Correa for bringing this matter to our attention.
Also moving some MCA params down from level 9 to levels 4/5.
* redefine orte_process_name_t so it can be converted
between host and network format as an opal_identifier_t
aka uint64_t by the OPAL layer.
* correctly send OPAL_DSTORE_ARCH key
Do not allow combination of transports that is not compliant with
shmem spec. Especially do not allow mix of hw and software atomic
ops
