I am wondering on how to specify with torque+mpiexec to spawn the parallel job on all 9 processors available on my my cluster. The cluster has 6 nodes of which 3 are dual processors and other 3 are uni-processors. These nodes are listed in the server_priv/nodes as:
node01 np=2 master
node02 np=2 slave
node03 np=2 slave
node04 np=1 slave
node05 np=1 slave
node06 np=1 slave
a) #PBS -l nodes=6:npp=2
b) #PBS -l nodes=6
mpiexec -np 9 ~/cpi
but both of these failed.
Any ideas on which option to use for all 9 processors?
thanks in advance for your time and help
PS: all jobs requiring maximum of 6 processors are working fine.
