A clarification -- this specific issue is during add_procs(), which, for jobs
that do not use the MPI-2 dynamics, is during MPI_INIT. The #3 error
detection/abort is not during the dynamic/lazy MPI peer connection wireup.
The potential for long timeout delays mentioned in #1 would be during the
I think Rolf's reply makes a possibly bad assumption - i.e., that this problem
is occurring just as the job is starting to run. Let me give you a real-life
example where this wasn't true, and where aborting the job would make a very
unhappy user:
We start a long-running job (i.e., days) on a ve

Jeff is correct - create an orte/odls/vxworks and do whatever you need for
that platform to launch a local child process.
I believe you will also find calls to fork/exec in the
orte/mca/ess/singleton area. You may want to add a configure.m4 to that
component to tell it not to build for vxworks.
Maybe gettimeofday() be replaced with opal_gettimeofday(), which could do the
Right Thing on different platforms...?
Also, for fork/exec, I think that should be mostly limited to
orte/odls/default, right? If so, perhaps the right thing to do is to clone
that plugin and adapt it for you platfor
Hi Castain ,
Your last mail to me is really helpful . I met most of the issues
listed and fixed them as the off-list solution or mine .
Also as the openmpi code changed there are some other issues (almost
the missing function ) that are not reported .For example , the
gettimeofday posix function i
