Provide a new MCA param that allows the user to direct that we abort the job once a process exits with non-zero status. No recovery is allowed in such cases to avoid trying to restart a process that has already exited MPI.

Only a minor change made to the current rsh module to avoid a naming conflict. Otherwise, left it alone to avoid creating conflicts with other external work. The current rsh module remains the default for rsh/ssh support, and continues to contain the support for SGE and Loadleveler.

Instead of returning MPI_SUCCESS every time they are called regardless of the status of the call, they should return a value representative of the action. So similar to MPI_Wait/MPI_Test they will return MPI_SUCCESS if the action was successfull, or the value that matches status.MPI_ERROR for the operation if it is unsuccessful.
This was discussed on the [http://www.open-mpi.org/community/lists/devel/2011/03/9109.php ompi-devel list]

If so, then setup the actual launch agent values only when the module init function is called.
This resolves the current conflict between the rsh and rshd components. Hopefully, it may avoid future problems in this area -provided- any new uses of rsh-like launchers abide by the lookup-and-then-setup rule.

* Convert from AC_TRY_RUN to AC_RUN_IFELSE.
* Excellent suggestion from Paul Hargrove: use AC_CHECK_FUNC to look
for a Linuxthreads-specific symbol when we're cross compiling to
see if threads will have different PIDs (because AC_CHECK_FUNC
works properly even when in cross-compiling environments).
Background: the old/Linuxthreads-based pthreads implementation used
the Linux clone() call to make threads, which effectively meant that
each thread had a different PID. The new NPTL pthreads implementation
does things better, meaning that threads have the same PID.
Open MPI no longer supports threads with different PIDs -- we ripped
out the supporting code for threads with different PIDs because we
don't have systems available to test this on anymore (anyone who still
has such a system can still use older versions of Open MPI). Hence,
configure needs to determine whether the target system will have the
same PID for threads or not -- even if we're cross-compiling. The
current test compiles and runs a multi-threaded app that checks PIDs
of different threads, but we clearly can't do that in a
cross-compiling environment. So use AC_CHECK_FUNC in cross-compiling
environments.
Simple, no?

There was no compelling reason to support such old kernels. Accordingly, convert the test to print a nice error message indicating we no longer support old kernels (but indicate that earlier OMPI versions do) and error out. Remove all code that was protected by "if have different pids" since it can no longer be compiled.

For some time, ORTE has had the ability to launch daemons on all nodes prior to launching an application. It has largely been used outside of the OMPI community, and so was never explicitly turned "on" inside OMPI releases. Nevertheless, the code has been there.
Allowing VM launches does not require ANY changes to existing PLM components. All that was required was to have orterun launch the daemons as a separate call to orte_plm.spawn -prior- to launching the applications. The rest of the VM support code resides in the rmaps framework:
(a) a check when asked to map a job to see if it is the daemon job, and
(b) a separate "setup_virtual_machine" mapper in the rmaps base that creates the required map so the PLM's will do the right thing.
In order to support those users who have no RM allocation but like to give the allocation in the form of a -host or -hostfile argument to their application, there is a little more code in orterun and the setup_virtual_machine mapper to capture information passed in that manner.
This has been tested with rsh and slurm environments, and, since there is nothing environment-specific in the implementation, should work in others as well - but needs to be proven.
