This merge adds Checkpoint/Restart support to Open MPI. The initial
frameworks and components support a LAM/MPI-like implementation.
This commit follows the risk assessment presented to the Open MPI core
development group on Feb. 22, 2007.
This commit closes trac:158
More details to follow.

yesterday and set it to "true" in orte_init(). But ompi_mpi_init()
doesn't call orte_init() -- it calls orte_init_stage1() and
orte_init_stage2(). So orte_initialized was never set to true, and
Badness happend from there (w.r.t. ompi_mpi_abort()).
This patch moves the setting of orte_initialized to orte_init_stage2()
so that everyone will always get it set properly.
It also moves setting orte_universe_info.state to RUNNING into
stage2() as well -- Ralph confirmed that that should have been there
for the same reasons that orte_initialized needs to be there.

completed successfully, Bad Things(tm) could happen.
* Now we explicitly check orte_initialized (a new global in ORTE
indicating whether we are between orte_init() and orte_finalize()
or not), and if so, react accordingly.
* If ORTE is initialized, use orte_system_info.nodename; otherwise,
use gethostname().
* Add loop protection to ensure that ompi_mpi_abort() is not invoked
multiple times recursively.

the ORTE_DAEMON_CMD type. Which, unfortunately, is used all over
the place. Without this, we get error:

1. add a "cancel_operation" API to the pls components that allows orterun to demand that an orted operation (e.g., terminate_job) be immediately cancelled and abandoned.
2. changes the pls orted commands from blocking to non-blocking. This allows us to interrupt those operations should an orted be non-responsive. The change also adds an orte_abort_timeout that limits how long orterun will automatically wait for the orteds to respond - if the terminate command, for example, doesn't see orted response within that time, then we printout an appropriate error message and just give up.
3. modifies orterun to allow multiple ctrl-c's to simply abort the program even if the orteds have not responded
4. does some cleanup on the orte-level mca params so that their implementation looks a lot more like that of ompi - makes it easier to maintain. This change also includes the definition of an orte_abort_timeout struct and associated MCA param (can't have too many!) so you can set the time after which orterun gives up on waiting for orteds to respond
This needs more testing before migrating to 1.2.

but remove them also. This current set of changes will affect
nothing as no one is making use of this ability. However, orte-clean
will be changed soon to utilize this new feature.

This has now been corrected. The singleton startup will dutifully call the mapper framework so that the proper data storage locations get initialized. Unfortunately, we then had to instruct the RMAPS not to allocate a vpid range for this job - otherwise, it would make a mistake and think there were two processes in it. Hence, a change was required to RMAPS to tell it "map this job, but don't allocate a vpid range for it".
This change will need to migrate across to 1.2 after it "soaks" the appropriate time.
This commit was SVN r12952.
Also, take the first step in updating how we handle mca params in ORTE - bring it closer to how it is done in the other two layers. Much more work to be done here.
This commit was SVN r12838.
the same time, remove some of the MPI-related options from OPAL:
- provide mechanism to change at runtime whether sched_yield() should
be called when the progress engine is idle
- provide mechanism for changing the rate at which the event engine
is called when there are "no" users of the event engine (ie, when
using MPI but not TCP)
- fix some function names in the progress engine to better match
their intended use (and remove MPI naming scheme)
- remove progress_mpi_enable / progress_mpi_disable because
we can now use the functions to set the sched_yield and
tick rate interfaces
- rename opal_progress_events() to opal_progress_set_event_flag()
because the first really isn't descriptive of what the function
does and I always got confused by it
This commit was SVN r12645.
Fix comm_spawn by singletons. orte_init does some voodoo to let the system know about localhost when we are a singleton. This includes allocating it so that any comm_spawn'd children can use their parent "allocation". Unfortunately, the fix that bproc needs (due to that smr filling up the node segment!) causes the singleton startup to fail. The fix is to just have the singleton startup force an allocation of its localhost.
Only issue here is: what happens if we are in a persistent universe? The singleton will now overwrite any prior info on slots used on localhost by other jobs (won't affect anything else). The answer, of course, is to do something more intelligent - lookup localhost on the registry and just update its info instead of overwriting it.
Something for another day (or month....or year)
This commit was SVN r12644.
Accordingly, there are new APIs to the name service to support the ability to get a job's parent, root, immediate children, and all its descendants. In addition, the terminate_job, terminate_orted, and signal_job APIs for the PLS have been modified to accept attributes that define the extent of their actions. For example, doing a "terminate_job" with an attribute of ORTE_NS_INCLUDE_DESCENDANTS will terminate the given jobid AND all jobs that descended from it.
I have tested this capability on a MacBook under rsh, Odin under SLURM, and LANL's Flash (bproc). It worked successfully on non-MPI jobs (both simple and including a spawn), and MPI jobs (again, both simple and with a spawn).

This commit was SVN r12257.
Fix the persistent daemon problem where it was exiting when a job completed. Problem was that the persistent daemon would order the job daemons to exit. They would then send an 'ack' back to the persistent daemon - but the ack consisted of an echo of the "exit" command, which was recv'd by the wrong listener who treated it as a properly sent cmd....and exited.
This commit was SVN r12243.
Fix the problem observed by multiple people that comm_spawned children were (once again) being mapped onto the same nodes as their parents. This was caused by going through the RAS a second time, thus overwriting the mapper's bookkeeping that told RMAPS where it had left off.
To solve this - and to continue moving forward on the ORTE development - we introduce the concept of attributes to control the behavior of the RM frameworks. I defined the attributes and a list of attributes as new ORTE data types to make it easier for people to pass them around (since they are now fundamental to the system, and therefore we will be packing and unpacking them frequently). Thus, all the functions to manipulate attributes can be implemented and debugged in one place.
I used those capabilities in two places:
1. Added an attribute list to the rmgr.spawn interface.
2. Added an attribute list to the ras.allocate interface. At the moment, the only attribute I modified the various RAS components to recognize is the USE_PARENT_ALLOCATION one (as defined in rmgr_types.h).
So the RAS components now know how to reuse an allocation. I have debugged this under rsh, but it now needs to be tested on a wider set of platforms.

different macros, one for each project. Therefore, now we have OPAL_DECLSPEC,
ORTE_DECLSPEC and OMPI_DECLSPEC. Please use them based on the sub-project.
This commit was SVN r11270.
Other changes:
1. Remove the old xcpu components as they are not functional.
2. Fix a "bug" in orterun whereby we called dump_aborted_procs even when we normally terminated. There is still some kind of bug in this procedure, however, as we appear to be calling the orterun job_state_callback function every time a process terminates (instead of only once when they have all terminated). I'll continue digging into that one.
This will require an autogen/configure, I'm afraid.
This commit was SVN r11228.
Clean up the remainder of the size_t references in the runtime itself. Convert to orte_std_cntr_t wherever it makes sense (only avoid those places where the actual memory size is referenced).
Remove the obsolete oob barrier function (we actually obsoleted it a long time ago - just never bothered to clean it up).
I have done my best to go through all the components and catch everything, even if I couldn't test compile them since I wasn't on that type of system. Still, I cannot guarantee that problems won't show up when you test this on specific systems. Usually, these will just show as "warning: comparison between signed and unsigned" notes which are easily fixed (just change a size_t to orte_std_cntr_t).
In some places, people didn't use size_t, but instead used some other variant (e.g., I found several places with uint32_t). I tried to catch all of them, but...
Once we get all the instances caught and fixed, this should once and for all resolve many of the heterogeneity problems.

- orte-clean.c : check to see if the base session directory is empty
and delete it if it is.
- orte_universe_exists.c : Fix a down stread problem resulting from
George's r10718 commit. Don't use the 'fulldirpath' since
that is no longer guarenteed to be the absolute path
to the session directory. Construct this value outside of that
function from the prefix and frontend vars.

After seeing the uglyness that is removing directories in the
codebase I decided to push down this to the OPAL by extending the
opal/os_create_dirpath.(c|h) to contain some more functionality.
In this process I renamed 'os_create_dirpath' to 'os_dirpath' since it
is a bit more general now.
Added a few functions to:
- check if an directory is empty
- check to see if the access permissions are set correctly
- destroy the directory at the end of the dirpath
- By using a caller callback function (a la Perl, I believe)
for every file, the caller can have fine grained control over
whether a specific file is deleted or not.
This simplifies things a bit for orte_session_dir_(finalize|cleanup)
as it should no longer contain any of this functionality, but uses
these functions to do the work.
From the external perspective nothing has changed, from the
developer point of view we have some cleaner, more generic code.

from the tmp/jjhursey-ft-cr branch.
In this commit we change the way universe names are created.
Before we by default first created "default-universe" then
if there was a conflict we created "default-universe-PID"
where PID is the PID of the HNP.
Now we create "default-universe-PID" all the time (when
a default universe name is used). This makes it much
easier when trying to find a HNP from an outside app
(e.g. orte-ps, orteconsole, ...)
This also adds a "search" function to find all of the
universes on the machine. This is useful in many contexts
when trying to find a persistent daemon or when trying to
connect to a HNP.
This commit also makes orte_universe_t an opal_object_t,
which is something that needed to happen, and only effected
the SDS in one of it's base functions.
I was asked to bring this over to aid in fixing orteconsole
and orteprobe. Due to the change of orte_universe_t to
an object orteprobe may need to be updated to reflect this
change. Since orteprobe needs to be looked at anyway I'll
leave this to Ralph to take care of.
*Note*:
These changes do not depend upon any of the FT work (but
the FT work does depend upon them). These were brought over
to help in fixing some of the ORTE tool set that require
the functionality layed out in this patch.
Testing:
Ran the 'ibm' tests before and after this change, and all was
as well as before the change. If anyone notices additional
irregularities in the system let me know. But none are expected.
