The problem was tracked to use of the grpcomm.onesided_barrier to control daemon/mpirun termination. This relied on messaging -and- required that the program counter jump from the errmgr back to grpcomm. On rare occasions, this jump did not occur, causing mpirun to hang.
This patch looks more invasive than it is - most of the affected files simply had one or two lines removed. The essence of the change is:
* pulled the job_complete and quit routines out of orterun and orted_main and put them in a common place
* modified the errmgr to directly call the new routines when termination is detected
* removed the grpcomm.onesided_barrier and its associated RML tag
* add a new "num_routes" API to the routed framework that reports back the number of dependent routes. When route_lost is called, the daemon's list of "children" is checked and adjusted if that route went to a "leaf" in the routing tree
* use connection termination between daemons to track rollup of the daemon tree. Daemons and HNP now terminate once num_routes returns zero
Also picked up in this commit is the addition of a new bool flag to the app_context struct, and increasing the job_control field from 8 to 16 bits. Both trivial.

(OMPI_ERR_* = OPAL_SOS_GET_ERR_CODE(ret)), since the return value could be a
SOS-encoded error. The OPAL_SOS_GET_ERR_CODE() takes in a SOS error and returns
back the native error code.
* Since OPAL_SUCCESS is preserved by SOS, also change all calls of the form
(OPAL_ERROR == ret) to (OPAL_SUCCESS != ret). We thus avoid having to
decode 'ret' to get the native error code.

Note that this isn't a problem since MPI_Abort and orte_abort are only called under controlled circumstances - i.e., we are doing an orderly abort and not segfaulting. If we can't get the message out for some reason, then too bad - we'll still see an abnormal process termination and act accordingly.

* add hnp and orted modules to the errmgr framework. The HNP module contains much of the code that was in the errmgr base since that code could only be executed by the HNP anyway.
* update the odls to report process states directly into the active errmgr module, thus removing the need to send messages looped back into the odls cmd processor. Let the active errmgr module decide what to do at various states.
* remove the code to track application state progress from the plm_base_launch_support.c code. Update the plm modules to call the errmgr directly when a launch fails.
* update the plm_base_receive.c code to call the errmgr with state updates from remote daemons
* update the routed modules to reflect that process state is updated in the errmgr
* ensure that the orted's open the errmgr and select their appropriate module
* add new pretty-print utilities to print process and job state. Move the pretty-print of time info to a globally-accessible place
* define a global orte_comm function to send messages from orted's to the HNP so that others can overlay the standard RML methods, if desired.
* update the orterun help output to reflect that the "term w/o sync" error message can result from three, not two, scenarios

Many of the OPAL_ENABLE_FT should be OPAL_ENABLE_FT_CR, so fix those.
The OPAL Layer INC should call opal_output on restart so that it can refresh the string it prints to reflect the current pid/hostname which may have changed.

Cleanup the kill_procs command by removing a no-longer-used param. We update the process state when the proc actually exits.
This commit was SVN r22783.
Modify the orte configure options to specify --enable-multicast such that it directs components to build or not instead of littering the code base with #if's. Remove those #if's where they used to occur.
Add a new grpcomm "mcast" module to support multicast operations. Still some work required to properly perform daemon collectives for comm_spawn operations. New module only builds when --enable-multicast is provided, and when specifically selected.

Have orte call setpgrp after forking (but before exec) when
orte_forward_job_control is set. Then have it send signals to the
child's process group. This allows suspending jobs that fork.
If a SIGTSTP arrives before the processes have been launched, then
record it and suspend them right after launching.

friends also receive &argc and &argv (George asked Jeff to Ralph to
review before committing). The thought is that passing argv and argc
to opal/orte_init be useful to other projects outside of OMPI that are
using OPAL and/or ORTE (especially in conjunction with some other
bootstrapping code where it is helpful to modify argv). It's such a
small thing that it's easy to apply here to make others' lives a
little easier.
Ask George for more details; I'm just the messenger. :-)
Judging by the copyrights on this patch, it's been around for a
while. :-)
This commit was SVN r22260.
Add orte configuration option to control the use of the framework in the system. Although the code will build, it will not be active unless configured with --enable-bootstrap.
If bootstrap is enabled and the new opal_sysinfo framework can successfully determine the cpu model, pass that info to the application as an MCA param to support some work at Sun.
Also, have daemons report back the resources they find to guide process mapping in bootstrap operations (i.e., where the daemon starts at node boot as opposed to being launched at application start).
Adjust some platform files to enable these capabilities.

Remove all architecture references from ORTE and put them back in the modex using modex_send/recv calls.
Hetero operations are now fully supported again. Comm_spawn now works up to the point where it segfaults due to an error in the CID code - which now allows Edgar to dig further! :-)

that now the HNP send the messages using the routed component. In the case
of tree spawn, when a intermediary node spawn a child it doesn't know how
to forward a message to it, so when the node-map message is coming from
the HNP (as there is nothing yet in the contact/routing table) the message
is sent back the way it came. As a result the node-map message keeps jumping
between the HNP and the first level orteds.
The solution is to add a new option to the children orte_parent_uri, which
is only set when the orted is _not_ directly spawned by the HNP. When this
option is present on the argument list, the orted will add the parent to
its routing, and force the parent to update his routes (by sending the URI).
With this approach, the routing tree is build in same time as the processes
are spawned, and all messages from the HNP can be routed to the leaves.
However, this is far from an optimal solution. Right now, this so called tree
spawn, only spawn the children in a tree without doing anything about the
"connect back to the HNP" step. The HNP is flooded with reports from all the
orted. The total number of messages is higher than in the non tree startup
scheme, so we do not expect this approach to be scalable in the current
incarnation. A complete overhaul of the tree startup is required in order
improve the scalability. Stay tuned!

This causes the orteds in the routing tree to remain alive until all termination "acks" from orteds below them have passed through. Thus, if we use static ports, we no longer require a direct orted-to-mpirun connection.
Also modify the binomial routed module so it conforms to what all the other routed modules do and have all messages pass along the routing tree instead of short-circuiting between orteds. This further reduces the number of ports being opened on backend nodes.

OMPI_* to OPAL_*. This allows opal layer to be used more independent
from the whole of ompi.

Cleanup the termination in orterun when abnormally commanded via ctrl-c. We can just directly terminate_orteds as the orteds always kill any lingering local procs before exiting - no need to do the two-step cha-cha.

- Delete unnecessary header files using
contrib/check_unnecessary_headers.sh after applying
patches, that include headers, being "lost" due to
inclusion in one of the now deleted headers...
In total 817 files are touched.
In ompi/mpi/c/ header files are moved up into the actual c-file,
where necessary (these are the only additional #include),
otherwise it is only deletions of #include (apart from the above
additions required due to notifier...)
