Ralph,
I downloaded and compiled the August 7 tarball with Torque/Maui support and ran
my test program – resulting in the same error when MPI_Comm_spawn was called.
Can you suggest anything the might be wrong with my environment or our Torque
configuration that might be causing this?
Thanks,
Ralph,
I got MPI_Comm_spawn to work by making sure that the hostfiles on the head
(where mpiexec is called) and the remote node are identical. I had assumed
that only the one on the head node was read by OpenMPI. Is this correct?
Thanks,
Kurt

Yeah, we do currently require that to be true. Process mapping is distributed
across the daemons - i.e., the daemon on each node independently computes the
map. We have talked about picking up the hostfile on the head node and sending
out the contents, but haven't implemented that yet.
