- 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.
This commit was SVN r11347.
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.

keep the resulting tm_event_t that is generated because the back-end
TM library actually caches a bunch of stuff on it for internal
processing, and doesn't let go of it until tm_poll().
tm_event_t's are similar to (but slightly different than)
MPI_Requests: you can't do a million MPI_Isend()'s on a single
MPI_Request -- a) you need an array of MPI_Request's to fill and b)
you need to keep them around until all the requests have completed.

/tmp/tm-merge). Validated by RHC. Summary:
- Add --nolocal (and -nolocal) options to orterun
- Make some scalability improvements to the tm pls

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.

- 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

it's always ORTE_SUCCESS and sometimes masks real !=ORTE_SUCCESS rc
values.
- Add MCA param pls_tm_want_path_check. If nonzero (the default),
check for the orted in the PATH before each tm_spawn()'ing (doing a
little caching so that we don't hammer on the filesystem -- remember
all the PATH's where we successfully found the orted so that we
don't have to query the filesystem multiple times for a PATH where
we previously found the orted)
- Be sure to opal_argv_split() the pls_tm_orted MCA param

session directory cleanup (among other things)
- When we get an abnormal exit in orterun (i.e., timeout expires and
we haven't gotten termination notices from all processes), print a
better message an exit in a better way (which includes session
directory cleanup)
- Fix tm and poe pls's to not exit() but rather propagate the error up
the stack (where relevant)
