Add a WANT_FT_CR flag different from WANT_FT so tools like *-checkpoint are not built when a different FT technique is requested.
Also fix the C/R thread check so that it is only enabled if C/R is enabled, not generally when threads are enabled.
This commit was SVN r24769.
Fix a bug in the new code that prevented the system from correctly matching addresses.
Remove comments in the show-help text indicating that we would continue in the face of incorrect specifications - leave that to the calling layer to decide.
Modify the new opal_ifmatches so it returns error codes letting the caller better understand the result.
Modify the oob to ensure we abort if we don't find interfaces matching specified constraints, and that we do so without multiple error messages.
NOTE: we have a conflict in our standards. We have been using comma-delimited lists of interfaces for all our params. However, one param - opal_net_private_ipv4 - now uses semicolons instead of comma separators. No idea why, but it is confusing.

Rather than try to support a bunch of lightweight environments like I did
with the Portals3 code, always use the "modex" and hack the grpcomm for
the SHMEM implementation to return the right nid/pid for a remote
process by "magic".

Correctly check the dependencies of MSYS env.
Set up configure include and lib path for building the package.
update a few more CMake scripts.

So separate out the printing of that key, and let the individual procs generate it in a way that ensures they all get the same result.
This commit was SVN r24646.
Rename the memusage sensor plugin to "resusage" as it will soon be updated to include full process stat monitoring.
Extend the heartbeat sensor to report node and process stats in the heartbeat.
Store the process and node stats in their respective orte_xxx_t object.
This commit was SVN r24629.
Provide a new MCA param that allows the user to direct that we abort the job once a process exits with non-zero status. No recovery is allowed in such cases to avoid trying to restart a process that has already exited MPI.

Only a minor change made to the current rsh module to avoid a naming conflict. Otherwise, left it alone to avoid creating conflicts with other external work. The current rsh module remains the default for rsh/ssh support, and continues to contain the support for SGE and Loadleveler.
This commit was SVN r24593.
If so, then setup the actual launch agent values only when the module init function is called.
This resolves the current conflict between the rsh and rshd components. Hopefully, it may avoid future problems in this area -provided- any new uses of rsh-like launchers abide by the lookup-and-then-setup rule.

There was no compelling reason to support such old kernels. Accordingly, convert the test to print a nice error message indicating we no longer support old kernels (but indicate that earlier OMPI versions do) and error out. Remove all code that was protected by "if have different pids" since it can no longer be compiled.

For some time, ORTE has had the ability to launch daemons on all nodes prior to launching an application. It has largely been used outside of the OMPI community, and so was never explicitly turned "on" inside OMPI releases. Nevertheless, the code has been there.
Allowing VM launches does not require ANY changes to existing PLM components. All that was required was to have orterun launch the daemons as a separate call to orte_plm.spawn -prior- to launching the applications. The rest of the VM support code resides in the rmaps framework:
(a) a check when asked to map a job to see if it is the daemon job, and
(b) a separate "setup_virtual_machine" mapper in the rmaps base that creates the required map so the PLM's will do the right thing.
In order to support those users who have no RM allocation but like to give the allocation in the form of a -host or -hostfile argument to their application, there is a little more code in orterun and the setup_virtual_machine mapper to capture information passed in that manner.
This has been tested with rsh and slurm environments, and, since there is nothing environment-specific in the implementation, should work in others as well - but needs to be proven.
This commit was SVN r24524.
1. removing the enum of mapper values
2. change the req_mapper and last_mapper fields to char* so they can hold the component name instead of a mapper flag
3. revise the selection logic in the mapper components to reflect the change. Components now look for their name in the req_mapper field, or to see if other criteria (e.g., npernode) are set that mandate their doing the mapping
Several MCA params resided in the rmaps base for historical reasons - they have been in the base since at least the original 1.2 release (and perhaps earlier). However, George correctly pointed out that they really should reside in their respective components. Accordingly, move them to the components, but register synonyms to the old names to avoid breaking backward compatibility.
These revisions retain the current functionality of allowing comm_spawn'd jobs to use different mappers than the original job, and for the errmgr to utilize the resilient mapper to recover processes regardless of how they were originally mapped.
Given the large number of possible combinations, I am sure that someone will find a corner-case combination of values and selection criteria that cause either no mapper to be selected, or one other than the intended to be used. No one can test all the ways people will use this system, so I expect debugging to continue for awhile.
The ability of comm_spawn'd jobs to exploit this functionality relies on changes to the orte_dpm component - this will be committed separately.

* If something goes wrong during ompi_mpi_init, don't erroneously
report that it is illegal to invoke MPI_INIT* before MPI_INIT
* Aggregate help messages when possible when something goes wring
during ompi_mpi_init

OMPI supports multiple different repository systems (SVN, hg, git).
But the VERSION file has listed "want_svn" and "svn_r" as fields, even
though the actual repo system and version may not be SVN.
So search/replace those fields (and derrivative values that come from
those fields) with "want_repo_rev" and "repo_rev", respectively.
This commit was SVN r24405.
When called, each mapper checks to see if it can map the job. If npernode is provided, for example, then the loadbalance mapper accepts the assignment and performs the operation - all mappers before it will "pass" as they can't map npernode requests.
Also remove the stale and never completed topo mapper.

Cleanup the heartbeat handling so it is associated with the proc, not a node.
Cleanup handling of recovery options so that defaults do not override user values iff they are provided.
This commit was SVN r24382.
Add some new proc/job states
Rename a constant to reflect coming change - remove the arbitrary difference between restarting a proc locally and relocating it to another node in terms of the number of restarts allowed.
Add pretty-print of signals for "proc aborted due to signal" reports.

This means that the converters (opal_err2str, orte_err2str) can now
return NULL as a "silent error". The return value of opal_err2str_fn_t
is the status of the operation (OPAL_SUCCESS or OPAL_ERROR).
This fixes the "Unknown error" message issues on the trunk.

This will prevent tools from segfaulting if the mpirun process goes away suddenly while they are trying to communicate with it over the OOB.
This commit was SVN r24365.
The problem is that the SStore components were not flushing the old, stale checkpoint information. As a result the checkpoint was writing into the wrong directory, which produced an invalid checkpoint.
This seems to be fixed now. Thanks to Alex Brick for the bug report.
This commit was SVN r24325.
(http://www.open-mpi.org/community/lists/users/2011/01/15427.php), the
--tv (and friends) switches to mpirun would effectively munge the
orterun command line together and then split it apart again before
exec'ing the underlying debugger. We would therefore lose multi-token
argv[x] value and split them into multiple tokens. For example:
mpirun --tv -np 2 a.out "foo bar"
would get launched with "foo" and "bar" as separate arguments; not one
argument. This was due to the underlying code joining the argv into a
single string and then re-splitting it. This commit removed the argv
join; it now does the parsing and re-jigering of the argv by only
looking at each individual argv item; multi-word tokens like "foo bar"
will never be split into separate tokens.

I want to thank Hugo Meyer for reporting this/these bugs.
Notes:
* Moved over a patch from the stabilization branch that makes sure we close the peer socket in the OOB TCP component fully during shutdown (after the de-registration sync). It also ensures that we free the rml_uri only after we are done communicating with the peer (in the odls_base deregister sync operation).
* When an error is detected while delivering messages, we really want to bail out of the loop since the error manager is likely mutating the orte_local_children data structure, so it is no longer safe to iterate over in the orte_odls_base_default_deliver_message() function.
* When the HNP is hosting processes make sure it accounts for processes that may have failed locally in the ErrMgr HNP component by decrementing the num_local_procs. This makes it match the orted ErrMgr component accounting. This is what was causing the modex to fail (the number of participants was wrong on a rolling recovery.
* The crmig and autor features of the hnp ErrMgr component now check for the jobid from both the 'job' parameter and from the process name (since one may be there and not the other). This caused some additional error messages during startup.
* If we fail to migrate (e.g., due to invalid node specification), print only the error message, not the error and success messages. This can be misleading.
This commit was SVN r24317.
* Fix the checkpoint-restart-checkpoint case which would previous reject the checkpoint of the newly restarted process. By making sure to re-enable checkpointing once the application has fully restarted fixes this issue (make sure to set is_app_checkpointable to true on restart confirmation).
* In the case of an invalid checkpoint, do not try to access the SStore datastore as it will be using a dummy handler, and return NULL strings. mpirun was segfaulting in the error case because it was trying to convert the seq_num from a string to an integer.
* Make sure to initialize the timer event in the Automatic Recovery section of the HNP errmgr, per the libevent update. This caused a segfault when attempting to recover a failed process.
* If ompi-checkpoint loses connection to the HNP/mpirun the TCP socket will fail and call the ErrMgr update_state function. This commit adds a dummy function {{{orte_errmgr_base_update_state()}}} that will prevent the ompi-checkpoint command from segfaulting in this error scenario.
This commit was SVN r24306.
* Improve the FTB notifier to publish (C/R, process/communication failure) events to the FTB with the
OMPI jobid as the associated payload.
* Add notifier calls for C/R events and process status events in SnapC and ErrMgr components.
* Fix a bug where the SnapC states and process states collide before being thrown out over the notifier.

It is statically initialized to the real back-end OPAL show_help
function. During orte_show_help_init(), the variable is re-assigned
with the value of the back-end ORTE show_help function (the one that
does error message aggregation).
Therefore, anything that calls opal_show_help() after a certain point
in orte_init() will have their show_help messages be aggregated.
w00t! Even code down in OPAL -- that has no knowledge of ORTE -- will
have their messages aggregated. '''Double w00t!'''
During orte_show_help_finalize(), we restore the original pointer
value so that it something calls opal_show_help() after
orte_finalize(), it'll still work properly (but it won't be
aggregated).

Restore the use of override_oversubscribe to indicate that the data source for resources on the backend nodes used in mapping is unreliable. In this situation (e.g., data came from hostfile, or we are just using localhost because nothing was provided), we don't trust the oversubscribe condition passed by the mapper. Instead, we check locally to ensure we set sched_yield correctly.
