Hi Rolf,
Thanks for answering!

Here is qstat -t, when I launch it with 8 processors. It looks to me
like it is actually using compute node 8. The mpirun job was submitted
on the head node 'nimbus'
Tried swapping out hostname for mpirun in the job script. For both 8
and 16
I assume it is working with np=8 because the 8 processes are getting
launched on the same node as mpirun and therefore there is no call to
qrsh to start up any remote processes. When you go beyond 8, mpirun
calls qrsh to start up processes on some of the remote nodes.
I would suggest first
Hi guys,
I'm trying to run an example program, mpi-ring, on a rocks cluster.
When launched via sge with 8 processors (we have 8 procs per node),
the program works fine, but with any more processors and the program
fails.
I'm using open-mpi 1.3.2, included below, at end of post, is output
