01fbb729e3 Need to get the nidmap so that the apps have something to look at for wireup.
Without this we get errors like the following since the nidmap is empty in the apps:
[[13094,1],1] ORTE_ERROR_LOG: Not found in file ess_env_module.c at line 234
[[13094,1],1] ORTE_ERROR_LOG: Not found in file ess_env_module.c at line 281

f3e13b9766 Improve the efficiency by making the check for uniqueness of incoming hnp contact info much faster by including the hnp_uri in the job_family tracker object. Replace the global buffer storage with a quick routine to build the buffer from the jobfams array

f85e69b64b Continue enabling connect_accept across large numbers of independent jobs by replacing the hash tables with pointer_arrays to store routes to remote hnps to gain flexibility we'll need in the future.

248320b91a Enable connect_accept between multiple singleton jobs without the presence of an external rendezvous agent (e.g., ompi-server). This also enables connect_accept between processes in more than two jobs regardless of how they were started.
Create an ability to store the contact info for multiple HNPs being used to route between different job families. Modify the dpm orte module to pass the resulting store during the connect_accept procedure so that all jobs involved in the resulting communicator know how to route OOB messages between them.

Add a test provided by Philippe that tests this ability.

12cd07c9a9 Start reducing our dependency on the event library by removing at least one instance where we use it to redirect the program counter. Rolf reported occasional hangs of mpirun in very specific circumstances after all daemons were done. A review of MTT results indicates this may have been happening more generally in a small fraction of cases.
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.

099c3aad97 Fix a major foopah that broke debugger attach. With the revisions in updating proc state, we dropped the recording of each proc's pid. Thus, attaching debuggers would find a proctable whose pids all equal 0.
This required modification of the errmgr.update_state API so the pid could be passed in to the function that could update the proper data record(s). All calls to that API have been updated as well, but I obviously couldn't test them all.

Thanks to Dong Ahn (LLNL) for catching this problem!

Also fixed debugger daemon cospawn, both for initial launch and attach-while-running modes. Tested and verified on rsh and slurm.

afbe3e99c6 * Wrap all the direct error-code checks of the form (OMPI_ERR_* == ret) with
(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.

efbb5c9b7c Revamp the errmgr framework to provide a greater range of optional behaviors, including different behaviors for daemons, and remove several looping messages across the code base:
* 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

e9b5162d79 Fix the configure logic for --with-ft so that it properly takes a comma separated list.
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.

8ab962411c Detect the scenario where one or more procs fail to call orte/ompi_init while others in the job do. This scenario can cause the job to hang as MPI_Init contains a barrier operation that will not complete. Although ORTE does not contain such a barrier, it still will be considered as an error scenario so that we can detect the MPI case - otherwise, ORTE has no knowledge of OMPI and wouldn't know how to differentiate the use-cases.
Take advantage of the changes to update the routed_base_receive code to avoid message overlap.

b97f885c00 Restore the original API to terminate individual processes instead of the entire job. This was originally removed as we didn't at that time know how to take advantage of it. Some of us are now working on proactive resilience methods that move procs prior to node failure, so this is now a required API. Modify the odls, plm, and orted functions to support this new functionality.
Continue work on the resilient mapper, completing support for fault groups.
