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.
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.

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).

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!

Only close off stdout/stderr from the daemons if we are not debugging the slurm pls and --debug-daemons was not passed.

The following Trac tickets were found above:
Ticket 352 --> https://svn.open-mpi.org/trac/ompi/ticket/352
This patch will cause a problem for cnos, however, as there we want to specifically tell the backends to be "null". I'm working on that issue.
This commit was SVN r12225.
I have tested on rsh, slurm, bproc, and tm. Bproc continues to have a problem (will be asking for help there).
Gridengine compiles but I cannot test (believe it likely will run).
Poe and xgrid compile to the extent they can without the proper include files.

- use the OPAL functions for PATH and environment variables
- make all headers C++ friendly
- no unamed structures
- no implicit cast.
Plus a full implementation for the orte_wait functions.

1. Changed the RMGR and PLS APIs to add "signal_job" and "signal_proc" entry points. Only the "signal_job" entries are implemented - none of the components have implementations for "signal_proc" at this time. Thus, you can signal all of the procs in a job, but cannot currently signal only one specific proc.
2. Implemented those new API functions in all components except xgrid (Brian will do so very soon). Only the rsh/ssh and fork modules have been tested, however, and only under OS-X.
3. Added signal traps and callback functions for SIGUSR1/2 to orterun/mpirun that catch those signals and call the appropriate commands to propagate them out to all processes in the job.
4. Added a new test directory under the orte branch to (eventually) hold unit and system level tests for just the run-time. Since our test branch of the repository is under restricted access, people working on the RTE were continually developing their own system-level tests - thus making it hard to help diagnose problems. I have moved the more commonly-used functions here, and added one specifically for testing the SIGUSR1/2 functionality.
I will be contacting people directly to seek help with testing the changes on more environments. Other than compile issues, you should see absolutely no change in behavior on any of your systems - this additional functionality is transparent to anyone who does not issue a SIGUSR1/2 to mpirun.

option as discussed on the devel-core mailing list. The Big
Difference is that instead of hard-coding the strings "/lib" and
"/bin" in to append to the prefix, we append the basename of the local
libdir and bindir. Hence, if your libdir is $prefix/lib64, we'll
append /lib64 to construct the remote node's LD_LIBRARY_PATH (etc.).
Also appended the orterun.1 man page to include a description of
--prefix, how it is constructed, what it handles / what it does not,
etc.

argv[0] and the cwd on the target node (i.e., the node where the
executable will be running in all systems except BProc, where the
searches are run on the node where orterun is invoked).
- fork pls now does cwd and argv[0] search in orted
- bproc pls does cwd and argv[0] search in orterun
- cwd behavior slightly different:
- if user specifies a -wdir to orterun, we chdir() to there; if we
can't for some reason, abort
- if user does not specify a -wdir, try to chdir() to the dir where
orterun was invoked. If we can't for some reason (e.g., it
doesn't exist on the target node), then try to chdir($HOME). If
we can't do that, then just live with whatever default directory
we were put in.

- move files out of toplevel include/ and etc/, moving it into the
sub-projects
- rather than including config headers with <project>/include,
have them as <project>
- require all headers to be included with a project prefix, with
the exception of the config headers ({opal,orte,ompi}_config.h
mpi.h, and mpif.h)

oversubscribed on a node. And thus whether to call sched_yield or not.
The value of node->node_slots_inuse does not currently represent the number of
slots actually in use, at the moment. This is actually a bug in the RAS/RMAPS
base components, but the fix for that specific bug is bigger than we want to
address at the moment (but will certianly do so in the near future).
Since we cannot trust this value, use the total number of mapped processes
(which was properly set by the RMAPS component upon mapping -- Just not
properly propagated back to the registry's node segment) from the process
mapping.
In addition to this change I cleaned up a couple of the debug messages. It
seems that TM and RSH are the only two directly effected by this. SLURM
would be if that section of code wasn't currently inactive, but put the fix
in for prosparity.

The logs from this branch are much more descriptive than I will put
here (including a *really* long description from last night). Here's
the short version:
- fixed some broken implementations in ras and rmaps
- "orterun --host ..." now works and has clearly defined semantics
(this was the impetus for the branch and all these fixes -- LANL had
a requirement for --host to work for 1.0)
- there is still a little bit of cleanup left to do post-1.0 (we got
correct functionality for 1.0 -- we did not fix bad implementations
that still "work")
- rds/hostfile and ras/hostfile handshaking
- singleton node segment assignments in stage1
- remove the default hostfile (no need for it anymore with the
localhost ras component)
- clean up pls components to avoid duplicate ras mapping queries
- [possible] -bynode/-byslot being specific to a single app context

This allows the user to specify certain options to srun when an application
is launched with this PLS.
A useful example is the need to set the time to wait from when the first
process completes and when slurm kills remaining processes:
pls_slurm_args=--wait=1200

it to be an exit.
* Put the srun process (or what is about to become the srun process) in
it's own process group so that group-wide signals (such as the
SIGINT sent by hitting cntl-c in a shell) are not sent to the srun
process.
