using intel mpi and torque, spawn rank 0 on one master node

[aksharb]

Hi,

we are using intel mpi and torque on rhel cluster. We want to spawn master process ( rank 0 ) on the master node ( 1 node of 8 procs ) and rest of the processes on 8 nodes ( i.e. 63 processes on 8 nodes, since each node is with 8 procs). How it can be done using mpi or pbs?

-s.d.

Hi,

You should be able to use the following format:

[plain]mpirun -n 1 -host master ./a.out : -n 63 -hostfile hosts.file ./a.out[/plain]
