ason to return the topology from every daemon. Borrow a page from the --hetero-apps page and let users indicate that the node topology differs by adding a --
hetero-nodes option to mpirun. If the option is set, then every daemon returns topology info. If not set, then only daemon vpid=1 returns it.
We always want one daemon to return the topology as the head node is often different from the compute nodes. Having one daemon return the compute node topolo
gy allows us to detect any such difference. All compute nodes are then set to the same topology.

Don't automatically display the topology for each node when --display-devel-map is set as it can overwhelm the reader. Use a separate flag --display-topo to get it.

To enable the epochs and the resilient orte code, use the configure flag:
--enable-resilient-orte
This will define both:
ORTE_ENABLE_EPOCH
ORTE_RESIL_ORTE

It was agreed that opal_init_util had wound up being used in unintended ways, which raised the problem of getting reference counts to work right. However, fixing it would involve more pain than it was worth - and so long as the other layers are made to behave similarly, I have no preference either way.
Complete implementation will follow - for now, this just reverts the prior changes.

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.

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.

No need for any CMRs to 1.5... that was already done in CMR 2728.

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.

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.

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.

(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.

It's not possible to combine two shared libraries on Windows, so we have to do it a bit different. First generate a small event static library by just linking the object files, and link it into other libraries that needs the libevent API.
This commit was SVN r24039.
Note: the ompi_check_libfca.m4 file had to be modified to avoid it stomping on global CPPFLAGS and the like. The file was also relocated to the ompi/config directory as it pertains solely to an ompi-layer component.
Forgive the mid-day configure change, but I know Shiqing is working the windows issues and don't want to cause him unnecessary redo work.
This commit was SVN r23966.
Setup the event API to support multiple bases in preparation for splitting the OMPI and ORTE events. Holding here pending shared memory resolution.
This commit was SVN r23943.
This is a fairly intrusive change, but outside of the moving of opal/event to opal/mca/event, the only changes involved (a) changing all calls to opal_event functions to reflect the new framework instead, and (b) ensuring that all opal_event_t objects are properly constructed since they are now true opal_objects.
Note: Shiqing has just returned from vacation and has not yet had a chance to complete the Windows integration. Thus, this commit almost certainly breaks Windows support on the trunk. However, I want this to have a chance to soak for as long as possible before I become less available a week from today (going to be at a class for 5 days, and thus will only be sparingly available) so we can find and fix any problems.
Biggest change is moving the libevent code from opal/event to a new opal/mca/event framework. This was done to make it much easier to update libevent in the future. New versions can be inserted as a new component and tested in parallel with the current version until validated, then we can remove the earlier version if we so choose. This is a statically built framework ala installdirs, so only one component will build at a time. There is no selection logic - the sole compiled component simply loads its function pointers into the opal_event struct.
I have gone thru the code base and converted all the libevent calls I could find. However, I cannot compile nor test every environment. It is therefore quite likely that errors remain in the system. Please keep an eye open for two things:
1. compile-time errors: these will be obvious as calls to the old functions (e.g., opal_evtimer_new) must be replaced by the new framework APIs (e.g., opal_event.evtimer_new)
2. run-time errors: these will likely show up as segfaults due to missing constructors on opal_event_t objects. It appears that it became a typical practice for people to "init" an opal_event_t by simply using memset to zero it out. This will no longer work - you must either OBJ_NEW or OBJ_CONSTRUCT an opal_event_t. I tried to catch these cases, but may have missed some. Believe me, you'll know when you hit it.
There is also the issue of the new libevent "no recursion" behavior. As I described on a recent email, we will have to discuss this and figure out what, if anything, we need to do.
