This fix includes two parts: (a) we now initialize the keyval pointer locations to NULL after the malloc, and (b) we now OBJ_NEW the keyvals prior to storing info in them.
BTW, in case anyone reads this and wonders why we don't just OBJ_NEW the keyvals in create_value, the reason is simply that some places in the code use static keyvals and simply assign those addresses into the value object's array. So not everyone wants to OBJ_NEW keyvals - by not forcing it here in create_value, we give the user the flexibility to do whatever they want.

* Set OMPI_BOOL_STRUCT_COPY to 1 if it's ok, 0 if it's not (i.e., PGI

* In two places in the code base -- orte-clean and btl_openib_ini.h,
we have a struct that contains a bool that is copied by value. In

to effect the following:
* The first time the user hits ctrl-c, we go into the process of
killing the ORTE job (this is not new).
* While waiting for the job to actually terminate, if the user hits
ctrl-c a second time, we print a warning saying "Hey, I'm still
trying to kill the job. If you *really* want me to die
immediately, hit ctrl-c again within 1 second."
* If the user hits ctrl-c a within 1 second, orterun quits with a
warning about how the job may not have actually been killed.
Note that none of this logic won't really work until the second part
of the fix for #726 is also committed (i.e., make pls.terminate_job()

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.

I also added a new orte constant (ORTE_ERR_SILENT) that allows us to pass up the chain that an error was encountered, but NOT print ORTE_ERROR_LOG messages. This is intended to be used for cases where the error we encounter is NOT an orte error, but rather is one associated with incorrect user input (e.g., the preceding case 2). In such cases, there is no point in printing an ORTE_ERROR_LOG chain of messages as it isn't an orte error.

I found only two places that were looking at the tokens:
1. the odls - we used the tokens to separately process the globals container data from everything else. In this case, I left the subscription that returned the globals data alone, but "stripped" the subscription that returned the launch data for the procs. These subscriptions have nothing to do with the xcast message.
2. the pml_base_modex - the callback function was getting process names from the returned tokens. Actually, this function was doing a very bad thing - it was assuming that the first token returned was *always* the process name. This is currently true, but is one of those assumptions that someone could have easily changed - and suddenly found the system inexplicably failing. I modified the function to (a) get the name sent back to us, (b) "stripped" the value structures of tokens and segment strings, and (c) correctly obtained process names from the returned values. I also reindented the heck out of the code so it was legible (at least, to my old eyes).

Also, change the dss buffer type mca param to something more easily remembered (it is now "dss_buffer_type"). Heck, even I had to keep looking at the darn code to remember it.
This commit was SVN r12728.
1. implement and enable the non-described buffer operations. I will send out a more detailed explanation separately. However, this mode of operation (which is now the default) significantly reduces message size during startup. If you want the described buffers, set the mca param "-mca dss_describe_buffer 1".
2. revise the xcast system to support both linear and binomial tree broadcast methods. Since we are seeing scenarios where the binomiall tree can cause problems, I have made the linear method the default. To run with the binomial tree, set the mca param "-mca oob_xcast_mode binomial".
3. add some detailed timing reports to the xcast operation. These are enabled via "-mca oob_xcast_timing 1".
4. add some more unit tests for the dss and gpr (focused on support for the non-described buffer)

Ralph identified the problem, I tracked down ''where'' the fd was
being closed, and Brian figured out ''why'' (and the fix).
What was happening is that a remote process was closing its
stdout/stderr and therefore sending a 0-byte IOF message to mpirun.
mpirun, in turn, closed the iof endpoint associated with that stream
(i.e., stdout/stderr). IOF does this to handle the case where
mpirun's stdin is closed -- this therefore causes the stdin on all the
ORTE-started processes to have their stdin's closed as well.
So the workaround here is to check that if we get a 0-byte IOF message
on a sink (indicating a remote closure), and if that sink is the
special stdout or stderr stream, don't actually close anything in the
local process.

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).

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 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.

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.

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!
