Does the $TORQUE/server_priv/nodes file on the Torque server should have
lines like this [with your
node's names, of course]?
node01 np=24 <maybe some more parameters>
Does your Torque/PBS script request 24 cores/processors per node?
Something like this:
#PBS -l nodes=4:ppn=24
mpiexec -np 96 <other mpiexec parameters> ./my_mpi_program
I think somebody already asked you to send your
and the output of
qmgr -c 'p s'
A snippet of your job submission script maybe too.
These things may help to understand what is the problem.
