[mvapich-discuss] poll_or_block_event

[Jonathan Perkins]

Jacob:
Thanks for your note.  Let's try to narrow down this issue a bit further.

What version of mvapich or mvapich2 are you using?  Does this problem
only happen with this application?  Are you able to get a back trace
from the process when this happens?

You may want to also considering upgrading to mvapich2-1.6 if you're
not already using this.  With this version, you're able to use the
mpiexec (hydra) that ships with mvapich2 itself.  This can help
isolate the issue as well.  For more information on this please see
