drp cluster

module use /gpfs/u/software/x86-rhel6/lmodulefiles/ module load ansys/[14.5|15.0]

Common Commands

ansys[145|150]  # ansys mechanical


The following slurm script runs mechanical 14.5 on $SLURM_NPROCS processes. If the ansys 15.0 module is loaded replace ansys145 with ansys150.

Create a file named with the following contents

#!/bin/bash -ex export MPI_WORKDIR=$PWD  #ANSYS will assume the working dir on rank!=0 processes is $HOME !!!! srun hostname -s > /tmp//hosts.$SLURM_JOB_ID if [ "x$SLURM_NPROCS" = "x" ]; then if [ "x$SLURM_NTASKS_PER_NODE" = "x" ];then SLURM_NTASKS_PER_NODE=1 fi SLURM_NPROCS=`expr $SLURM_JOB_NUM_NODES \* $SLURM_NTASKS_PER_NODE` fi cat /tmp//hosts.$SLURM_JOB_ID # format the host list for mechanical mech_hosts="" for host in `sort -u /tmp//hosts.$SLURM_JOB_ID`; do n=`grep -c $host /tmp//hosts.$SLURM_JOB_ID` mech_hosts=$(printf "%s%s:%d:" "$mech_hosts" "$host" "$n") done # run the solver echo "hosts ${mech_hosts%%:}" ansys145 -dis -b -machines ${mech_hosts%%:} -i problem.dat -o run.out # cleanup rm /tmp/hosts.$SLURM_JOB_ID

Submit the job to use 16 processes across two nodes with a max wall time of 10 minutes
