d4f56cff61 More cleanup on paffinity....groan 
It is okay to not have a paffinity module IF you aren't using paffinity anyway. So don't error out of MPI_Init because a paffinity module wasn't selected.

Cleanup error reporting in the odls default module to (once and for all!) eliminate messages originating in the fork'd process. Create some new error codes to allow us to pass enough info back to the parent process to provide useful error messages.

c93af95351 Since there is no defined behavior for the case where all application procs exit normally, but some or all have non-zero returns, just output a warning telling the user how many procs meet that criteria. Let the return code of mpirun in that scenario reflect any errors in OMPI/ORTE itself. 
Clearly a temporary solution until a defined behavior can be established.

1. orte_enable_recovery - default recovery policy, can be overridden on a per-job basis

2. orte_max_local_restarts - default max number of local restarts, can be overridden

3. orte_max_global_restarts - default max number of relocates, can be overridden

55889934d8 After hours spent chasing the stupid "abort" file, it became clear that we were always going to be plagued by that idiot contraption when trying to be good citizens and properly cleanup. So get rid of it by instead doing a messaging handshake with the local daemon. 
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.

b9893aacc5 Add a sensor framework to ORTE that monitors applications and notifies the errmgr when they exceed specified boundaries. Two modules are included here: 
1. file activity - can monitor file size, access and modification times. If these fail to change over a specified number of sampling iterations (rate is an mca param), then the errmgr is notified.

2. memory usage - checks amount of memory used by a process. Limit and sampling rate can be set.

This support must be enabled by configuring --enable-sensors.

ompi_info and orte-info have been updated to include the new framework.

Also includes some initial steps toward restoring the recovery capability. Most notably, the ODLS API has been extended to include a "restart_proc" entry for restarting a local process, and organizes the various ERRMGR framework globals into a single struct as we do in the other ORTE frameworks. Fix an oversight in the ERRMGR framework where a pointer array was constructed, but not initialized.

Implementation continues.

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

b400b84162 Merge in the modified thread configure option branch per today's telecon. 
Remove the --enable-progress-threads option as this is no longer functional, and hardcode OPAL_ENABLE_PROGRESS_THREADS to 0.

Replace the --enable-mpi-threads option with --enable-mpi-thread-multiple as this is clearer as to meaning. This option automatically turns "on" opal thread support if it wasn't already so specified. If the user specifies --disable-opal-multi-threads --enable-mpi-thread-multiple, we will error out with a message

Add a new --enable-opal-multi-threads option that turns "on" opal thread support without doing anything wrt mpi-thread-multiple

ffd5be6aa1 Add a new framework to ORTE for saving and recovering state information. Two components are included that use the db or dbm library for storing the data, with a distributed hash table component coming later. 
Note that each of these components will only be selected if specifically requested - otherwise, a "NULL" component will be used.  The framework is only opened by the HNP and orteds, though neither is currently coded to save/restore state

ef6c432e22 Fix a nasty bug where we would hang if an application trapped signals such as SIGTERM - a permissible thing to do. In such cases, we removed the process from the waitpid system and then sent it a SIGTERM. If the application trapped that and attempted to cleanly terminate, it would send us a sync message - and the daemon would then add it back to its local child list, causing both the daemon and the process to hang. 
In this revision, we let the process terminate/exit however it can, and then pick it up via the usual waitpid.

http://www.open-mpi.org/community/lists/devel/2010/02/7447.php.

Specifically:

 * Create LT convenience libraries for OPAL and ORTE if the layer
   above them is being created (use the already-defined
   AM_CONDITIONALs to know if the project above us is being built).
 * ORTE slurps in the LT convenience library for OPAL; OMPI slurps in
   the LT convenience library for ORTE.
 * Wrapper compilers now only -l one library (e.g., ortecc only does
   -lopen-ret, and mpicc only does -lmpi).

b749ecbab8 This commit fixes trac:2190. 
Originally the patch was to improve the error message, but when digging into the code I found a subtle bug. If the daemon does not tell the HNP what CRS component it used, then the HNP tries to figure it out from the metadata (this is an uncommon case). The path the HNP used was not complete, so it was unable to find the metadata information. This patch fixes this by adding the 'snapshot_reference' to the 'snapshot_location' which completes the path for this search.

237eb4e8df For some strange reason, every so often it appears possible for the event library to trip the read event on a socket, yet have the read itself yield an error. If/when that happens, report the error and continue on. 
This happens rarely, but it does seem to happen.

09763ec711 Since we modified ORTE to declare that any process that terminates after calling "init" while at least one other process has not yet called "init" is an error, we have to ensure that non-MPI ORTE apps (i.e., apps that call orte_init but not mpi_init) include a barrier in orte_init. Otherwise, fast ORTE apps almost always wind up triggering the "abnormal termination" condition. 
The barrier is protected with a test to ensure that MPI apps don't execute it and wind up doing two barriers during their init.

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.

a2310808f1 Santa's back! Fix all warnings about the deprecated usage of 
stringWithCString as well as the casting issue between NSInteger and
%d. The first is solved by using stringWithUTF8String, which apparently
will always give the right answer (sic). The second is fixed as suggested
by Apple by casting the NSInteger (hint: which by definition is large
enough to hold a pointer) to a long and use %ld in the printf.

4357159ac9 Make sure to check for the NO_CKPT state while waiting. This means that the target was not able to checkpoint [ever | at this time]. So {{{ompi-checkpoint}}} should exit after printing the error message, instead of hanging and waiting. 
Will need to be moved to v1.5 and v1.4. v1.4 will require a custom patch, but should apply cleanly to v1.5. CMRs to follow.
