I am having a bit of a problem getting udapl to work via mpirun (over open-mpi, obviously). I am running a basic pingpong test and I get the following error.
# mpirun --n 2 --host vic12-10g,vic20-10g -mca btl udapl,self /usr/mpi/gcc/open*/tests/IMB*/IMB-MPI1 pingpong -------------------------------------------------------------------------- Process 0.1.1 is unable to reach 0.1.0 for MPI communication.

So I think my setup is correct. Also, dapltest successfully completes without any problems over IB or iWARP. Any thoughts or suggestions would be greatly appreciated. Thanks, Jon
