It must be making contact or ORTE wouldn't be attempting to launch your application's procs. Looks more like it never received the launch command. Looking at the code, I suspect you're getting caught in a race condition that causes the message to get "stuck".

Both use a different timing mechanism intended to resolve such situations. On Dec 14, 2012, at 2:49 PM, Daniel Davidson <dani...@igb.uiuc.edu> wrote: > Thank you for the help so far.
