I am using I am using a HPC
Apro green server
Centos 6.3 Linux based
256 core

Since the HPC has time limit 72:00:00 I am not able to finish my calculation within the time. How could I optimize my resources use to finish job in time.
I can use Distributed MPI parallel for my calculations

Thank You

Following is my script file :
#@ resources = ConsumableCpus (1) ConsumableMemory(2gb)

#@ wall_clock_limit =72:00:00

#@ total_tasks =32

#@ blocking =unlimited
. /applic/Applications/env_setup/cfx_v150.env

nodes=`cat $LOADL_HOSTFILE`
nodes=`echo $nodes | sed -e 's/ /,/g'`

export CFX5RSH=ssh

cfx5solve -mdef CFX.mdef -start-method "Platform MPI Distributed Parallel" -par -def

You can set wall clock limit in CFX Pre. So the simulation will stop at say...71 hours.
Can you then just restart the simulation using the previous results file as initial conditions? Therefore, just breaking it into two+ runs?
