This commit fixes two bugs in XRC support
- When dynamic add_procs support was added to master the remote
process name was added to the non-XRC request structure. The same
value was not added to the XRC xconnect structure. This error was
not caught because the send/recv code was incorrectly using the
wrong structure member. This commmit adds the member and ensure the
xconnect code uses the correct structure.
- XRC loopback QP support has been fixed. It was 1) not setting the
correct fields on the endpoint structure, 2) calling
udcm_xrc_recv_qp_connect, and 3) was not initializing the endpoint
data.

mca_btl_openib_put incorrectly checks the qp inline max before
allowing an inline put. This check will always fail for an endpoint
that has not been connected. The commit changes the check to use the
btl_put_local_registration_threshold instead.

Commit open-mpi/ompi@400af6c52d
introduced a regression in XRC support. The commit reversed the
ordering of shared receive queue (SRQ) and completion queue (CQ)
completion. CQ creation must always preceed SRQ creation when using
XRC as the CQs are needed to create the SRQs. This commit fixes the
ordering so that CQs are always created before SRQs.

libmpi.so cannot be built (unresolved symbols) with configure'd with

* Clean up the DVM so it continues to run even when applications error out and we would ordinarily abort the daemons.
* Create a new errmgr component for the DVM to handle the differences.
* Cleanup the DVM state component.
* Add ORTE bindings directory and brief README
* Pass a local tool index around to match jobs.
* Pass the jobid on job completion.
* Fix initialization logic.
* Add framework for python wrapper.
* Fix terminate-with-non-zero-exit behavior so it properly terminates only the indicated procs, notifies orte-submit, and orte-dvm continues executing.
* Add some missing options to orte-dvm
* Fix a bug in -host processing that caused us to ignore the #slots designator. Add a new attribute to indicate "do not expand the DVM" when submitting job spawn requests.
* It actually makes no sense that we treat the termination of all children differently than terminating the children of a specific job - it only creates confusion over the difference in behavior. So terminate children the same way regardless.
Extend the cmd_line utility to easily allow layering of command line definitions
Catch up with ORTE interface change and make build more generic.
Disable "fixed dvm" logic for now.
Add another cmd_line function to merge a table of cmd line options with another one, reporting as errors any duplicate entries. Use this to allow orterun to reuse the orted_submit code
Fix the "fixed_dvm" logic by ensuring we reset num_new_daemons to zero. Also ensure that the nidmap is sent with the first job so the downstream daemons get the node info. Remove a duplicate cmd line entry in orterun.
Revise the DVM startup procedure to pass the nidmap only once, at the startup of the DVM. This reduces the overhead on each job launch and ensures that the nidmap doesn't get overwritten.
Add new commands to get_orted_comm_cmd_str().
Move ORTE command line options to orte_globals.[ch].
Catch up with extra orte_submit_init parameter.
Add example code.
Add documentation.
Bump version.
The nidmap and routing data must be updated prior to propagating the xcast or else the xcast will fail.
Fix the return code so it is something more expected when an error occurs. Ensure we get an error returned to us when we fail to launch for some reason. In this case, we will always get a launch_cb as we did indeed attempt to spawn it. The error code will be returned in the complete_cb.
Fix the return code from orte_submit_job - it was returning the tracker index instead of "success". Take advantage of ORTE's pretty-print capabilities to provide a nice error output explaining why we failed to launch. Ensure we always get a launch_cb when we fail to launch, but no complete_cb as the job never launched.
Extend the error reporting capability to job completion as well.
Add index parameter to orte_submit_job().
Add orte_job_cancel and implement ORTE_DAEMON_TERMINATE_JOB_CMD.
Factor out dvm termination.
Parse the terminate option at tool level.
Add error string for ORTE_ERR_JOB_CANCELLED.
Add some safeguards.
Cleanup and/of comments.
Enable the return.
Properly ORTE_DECLSPEC orte_submit_halt.
Add orte_submit_halt and orte_submit_cancel to interface.
Use the plm interface to terminate the job
Cleanup the configury so we properly check for Singularity under the various typical use-cases
Bring the Singularity support online. We have to turn "off" the sm BTL as it segfaults from inside the container - root cause remains unclear. Also turned "off" the various OPAL shmem components in case they are involved and someone else tries to use them. Happily, the vader BTL works just fine!
Nowhere in the standard does it say that it is invalid to pass
MPI_BOTTOM to MPI_Get_address yet we were returning an error. This
commit removes the error check on NULL == location.

These changes fix issue https://github.com/open-mpi/ompi/issues/1336
- improve abstractions: opal/memory/linux component should be single place that opeartes with
Memory Allocation Hooks.
- avoid collisions in case dynamic component open/close: it is safe because it is linked statically.
- does not change original behaivour.
converting an opal_process_name_t means the loss of one bit,
it was decided to restrict the local job id to 15 bits, so the
useful information of an opal_process_name_t can fit in 63 bits.
As reported by @marksantcroos, this substitution in opal.pc was
incorrect -- it left @{libdir} in the string (vs. ${libdir}). The fix
is simple: use the proper substitution variable in opal.pc (it was
never updated to reflect the new/correct name that was created just
for the pkg-config files).
Fixesopen-mpi/ompi#1343.
This commit fixes several bugs identified by @ggouaillardet and MTT:
- Fix SEGV in long send completion caused by missing update to the
request callback data.
- Add an MPI_Barrier to the fence short-cut. This fixes potential
semantic issues where messages may be received before fence is
reached.
- Ensure fragments are flushed when using request-based RMA. This
allows MPI_Test/MPI_Wait/etc to work as expected.
- Restore the tag space back to 16-bits. It was intended that the
space be expanded to 32-bits but the required change to the
fragment headers was not committed. The tag space may be expanded
in a later commit.

to a common/verbs_usnic symbol in the common/verbs component. This
call needs to be compiled out when the common/verbs_usnic component is
not built.
This commit fixes several bugs identified by a new multi-threaded RMA
benchmarking suite. The following bugs have been identified and fixed:
- The code that signaled the actual start of an access epoch changed
the eager_send_active flag on a synchronization object without
holding the object's lock. This could cause another thread waiting
on eager sends to block indefinitely because the entirety of
ompi_osc_pt2pt_sync_expected could exectute between the check of
eager_send_active and the conditon wait of
ompi_osc_pt2pt_sync_wait.
- The bookkeeping of fragments could get screwed up when performing
long put/accumulate operations from different threads. This was
caused by the fragment flush code at the end of both put and
accumulate. This code was put in place to avoid sending a large
number of unexpected messages to a peer. To fix the bookkeeping
issue we now 1) wait for eager sends to be active before stating
any large isend's, and 2) keep track of the number of large isends
associated with a fragment. If the number of large isends reaches
32 the active fragment is flushed.
- Use atomics to update the large receive/send tag counters. This
prevents duplicate tags from being used. The tag space has also
been updated to use the entire 16-bits of the tag space.
These changes should also fixopen-mpi/ompi#1299.
