ANSYS

The ANSYS suite of programs is available on the ITS-RS HPC system.

To use them, you will need to have access to a license server that will validate your right to use the software. The license servers are not run on the HPC systems so please check with your department for more information. 

The command line flags used with Ansys have changed somewhat in version 18.x to accommodate a new interconnect called Omni-Path.

#$ -pe 56cpn 112

module load ansys/18.0_impi-2017.4
fluent 3ddp -t$NSLOTS -g -cnf=$TMPDIR/machines -sge -pib.infinipath -mpi=intel -i File.in > File.out

Argon provides versions 17.2 and 18.0.   When running Ansys programs on Argon, the -pib.infinipath must be explicitly stated for interconnect selection and the MPI implementation chosen must be mpi=intel. If these are not specified, the job will either fail outright or fall back to a much slower interconnect, severely curtailing performance. The environment modules that set the necessary variables and paths on Argon are not currently the default Ansys modules. When loading environment modules on Argon, ensure that you are using either ansys/17.2_impi-2017.4 or ansys/18.0_impi-2017.4 for your jobs.
