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

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.
We were burned again by the fact that the bproc state monitor creates entries on the node segment for *all* the nodes in the cluster when it is opened during orte_init. As a result, the bjs allocator was never being called, and the system merrily assumed that *all* nodes in the cluster had been allocated to it.
To fix this, I removed a test that had been inserted into the allocation procedure that checked for a non-zero node segment. This was an old artifact - the RAS components already know that they are not to overwrite any existing node segment entries (at least, bproc does - I will check the others. For now, I just want to save the bproc fix on this machine).

Modify the RMAPS framework so we eliminate communicating a map to a backend node when certain attributes are set. The proxy functions are now implemented in the base, and a check made for HNP/non-HNP operation made in the map_jobs function prior to execution.
This commit was SVN r12619.
Add placeholders for the new orte tools. These don't actually do anything yet - in fact, I have set the .ompi_ignore so that you won't compile them (I have set a .ompi_unignore for me). Please let me know if you encounter any trouble with this - the ompi_ignore's should protect everyone.
This commit was SVN r12616.
Note that Bproc won't support this operation, so we just ignore the --reuse-daemons directive.
I'm afraid I don't understand the POE and XGrid environments well enough to attempt the necessary modifications.
Also, please note that XGrid support has been broken on the trunk. I don't understand the code syntax well enough to make the required changes to that PLS component, so it won't compile at the moment. I'm hoping Brian has a few minutes to fix it after SC.
This commit was SVN r12614.
1. new functionality in the pls base to check for reusable daemons and launch upon them
2. an extension of the odls API to allow each odls component to build a notify message with the "correct" data in it for adding processes to the local daemon. This means that the odls now opens components on the HNP as well as on daemons - but that's the price of allowing so much flexibility. Only the default odls has this functionality enabled - the others just return NOT_IMPLEMENTED
3. addition of a new command line option "--reuse-daemons" to orterun. The default, for now, is to NOT reuse daemons. Once we have more time to test this capability, we may choose to reverse the default. For one thing, we probably want to investigate the tradeoffs in start time for comm_spawn'd processes that reuse daemons versus launch their own. On some systems, though, having another daemon show up can cause problems - so they may want to set the default as "reuse".
This is ONLY enabled for rsh launch, at the moment. The code needing to be added to each launcher is about three lines long, so I'll be doing that as I get access to machines I can test it on.

1. use non-blocking sends to transmit commands (this was actually done in a prior commit)
2. have an "ack" message sent back from the orted when it completes the command
The latter item is the new one here. With my prior commit, it was possible for the HNP to move on to other things before the orted had completed its command. This caused the HNP to occassionally exit before the orted, thus generating "lost connection" errors. With this change, we retain the parallel nature of the command communications, but still hold the HNP at that point until the orteds are done.
Best of both worlds.
This commit was SVN r12605.
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).

Add some debugger output to the ODLS default component.
Modify the orted command communication system so that it is done via non-blocking sends. This removes the linearity of the transmission and improves the response time.

Add some debugging output to the ODLS default module, and the orted.
Remove the nodename data from the ODLS info report - that info is already stored in the registry by the RMAPS framework upon completing the mapping procedure.
Add another test program that does an ORTE-only dynamic spawn (gasp!). Looks just like comm_spawn - just no MPI involved.
Modify the ODLS to release the processor when we "kill" local procs in a more scalable fashion. It previously had a sleep in it that Jeff's prior commit removed. However, he introduced some Windows code into the non-Windows component (protected by "if"s, but unnecessary). This is a more general solution he proposed - included here so I could get things to compile properly.
This commit was SVN r12579.
1. Fix the "hang" condition when an application isn't found. It turned out that the ODLS had some difficulty with the process actually not having been started - hence, it never called the waitpid callback. As a result, the "terminated" trigger didn't fire, and so mpirun didn't wake up. With this change, the HNP's errmgr forces the issue by causing the trigger to fire itself when an abort condition occurs.
2. Shift the recording of the pid and the nodename from mpi_init to the orted launcher. This allows programs such as Eclipse PTP to get the pids even for non-MPI applications. In the case of bproc, the pls handles this chore since we don't use orteds in that system.

check for bourne shell, because bourne shell is the smallest
common divisor for bash/ksh/sh.
- Make some shell expressions sh compatible
This commit was SVN r12509.
1. Added reporting points around the xcasts in MPI_Init. Note that these times will include time spent waiting for a trigger to fire, which is why the times between stage gates did NOT include these times initially. The inter-stage-gate times still do NOT include the xcast time - the xcast time is reported separately.
2. Added the process vpid on the MPI_Init timing reports for clarity.
3. Added a report from the xcast function on the HNP that outputs the number of bytes in the message being sent to the processes.
This commit was SVN r12422.
1. ORTE_RMAPS_DISPLAY_AT_LAUNCH: pretty-prints out the process map right before we launch so you can see where everyone is going. This is settable via the command line option "--display-map-at-launch"
2. ORTE_RMGR_STOP_AFTER_SETUP: just setup the job and then return from the spawn command.
3. ORTE_RMGR_STOP_AFTER_ALLOC: return from the rmgr.spawn call after allocating the job
4. ORTE_RMGR_STOP_AFTER_MAP: return from the rmgr.spawn call after mapping the job. This gives folks a chance to retrieve and graphically display the map, let the user edit it, and store the results. They can then call "launch" on their own and the system will use the revised map.
Enjoy! My personal favorite is the first one - helps with debugging.

Setup subscriptions to correctly return the MPI_APPNUM attribute.
Fix an unreported bug that was found. The universe size was incorrectly defined in the attributes code. As coded, it looked for size_t values and based its size computation on those numbers. Unfortunately, the node_slots value had been changed to an orte_std_cntr_t awhile back! So the universe size was never updated.
Update the hello_nodename test to check for MPI_APPNUM.
Add a definition to ns_types for ORTE_PROC_MY_NAME - just a shortcut for orte_process_info.my_name. Brought over from ORTE 2.0 as it will be used extensively there.

If you want to look at our launch and MPI process startup times, you can do so with two MCA params:
OMPI_MCA_orte_timing: set it to anything non-zero and you will get the launch time for different steps in the job launch procedure. The degree of detail depends on the launch environment. rsh will provide you with the average, min, and max launch time for the daemons. SLURM block launches the daemon, so you only get the time to launch the daemons and the total time to launch the job. Ditto for bproc. TM looks more like rsh. Only those four environments are currently supported - anyone interested in extending this capability to other environs is welcome to do so. In all cases, you also get the time to setup the job for launch.
OMPI_MCA_ompi_timing: set it to anything non-zero and you will get the time for mpi_init to reach the compound registry command, the time to execute that command, the time to go from our stage1 barrier to the stage2 barrier, and the time to go from the stage2 barrier to the end of mpi_init. This will be output for each process, so you'll have to compile any statistics on your own. Note: if someone develops a nice parser to do so, it would be really appreciated if you could/would share!
