That seems like a bug to me. What version of Open MPI are you using? How have you setup the C/R functionality (what MCA options do you have set, what command line options are you using)? Can you send a small reproducing application that we can test against?
That should help us focus in on the problem a bit. -- Josh On Wed, Aug 31, 2011 at 6:36 AM, Faisal Shahzad <itsfa...@hotmail.com> wrote: > Dear Group, > I have a mpi-program in which every process is communicating with its > neighbors.
