MPI run crashes on more than one node

Hello,

KInd Attn: James Tullos (Intel)

I am facing a similar problem like http://software.intel.com/en-us/forums/topic/487208 and http://software.intel.com/en-us/forums/topic/280123#comment-

My mpirun crashes giving the below error message.

[proxy:0:4@cn004] HYDT_dmxu_poll_wait_for_event (./tools/demux/demux_poll.c:70): assert (!(pollfds[i].revents & ~POLLIN & ~POLLOUT & ~POLLHUP)) failed

[mpiexec@hn1] main (./ui/mpich/mpiexec.c:548): process manager error waiting for completion

I have also tried the command [bash]mpirun -np N -check_mpi ./wrf.exe which is not giving any output.

Thanks for your help and support.

Regards
