Thanks for the bug report. There are a couple of places in the code that, in a sense, hard code '/tmp' as the temporary directory. It shouldn't be to hard to fix since there is a common function used in the code to discovery the 'true' temporary directory (which defaults to /tmp). Of course there might be other complexities once I dig into the problem.

I don't know when I will get to this, but I filed a ticket about this if you want to track it:

Thanks again,
Josh

Josh,

I was following this thread as I had similar symptoms and discovered a
peculiar error.  when I launch the program, openmpi follows the
$TMPDIR environment variable and puts the session information in the
$TMPDIR directory.  However ompi-checkpoint seems to be requiring the
sessions file to be in /tmp ignoring the $TMPDIR.  Is this by design
and what would I have to do to get it to obey the $TMPDIR environment
variable.
