Yes, i am setting the config correcty. Our IB machines seem to run just fine so far using srun and openmpi v1.5. As another data point, we enabled mpi-threads in Openmpi and that also seems to trigger the Srun/TCP behavior, but on the IB fabric. Running the program within an salloc rather the

Hi all, I tried a google/mailing list search for this but came up with nothing, so here goes: Is there any level of automation between open mpi's dynamic process management and the SGE queue manager? In particular, can I make a call to mpi_comm_spawn and have SGE dynamically increase the
