Example jobs

Choosing the correct pe

Please note the instructions regarding choosing the correct pe for single-node and multi-node jobs.

One node or less

Here is an example job running on 4 cores and 16G of ram on a single node.

SMP Process Forking

If the I_MPI_HYDRA_BOOTSTRAP environment variable is not set, the job will fail with error message: execution daemon on host HOST didn't accept task.

#!/bin/bash
#$ -cwd
#$ -j y
#$ -pe smp 4
#$ -l h_rt=4:0:0
#$ -l h_vmem=4G

module load star-ccm+
export I_MPI_HYDRA_BOOTSTRAP=fork
starccm+ -power -podkey [POD-KEY] -batchsystem sge -mpidriver intel -batch [SIM-FILE]

Multi-node job

Here is an example of a multi-node job running on 64 cores and utilising the nxv infiniband island.

#!/bin/bash
#$ -cwd
#$ -j y
#$ -pe parallel 64
#$ -l infiniband=nxv
#$ -l h_rt=4:0:0

module load star-ccm+
starccm+ -power -podkey [POD-KEY] -batchsystem sge -mpidriver intel -batch [SIM-FILE]
