@ -75,10 +75,13 @@ An example for running CFX using a Slurm batch script is the following:
module use unstable
module load ANSYS/2020R1-1
export HOSTLIST=$(scontrol show hostname | tr '\n' ',' | sed 's/,$//g')
JOURNAL_FILE=/data/user/caubet_m/CFX/myjournal.in
cfx5solve -batch -def "$JOURNAL_FILE" -part $SLURM_NTASKS
cfx5solve -batch -def "$JOURNAL_FILE" -par-dist "$HOSTLIST" -part $SLURM_NTASKS -start-method 'IBM MPI Distributed Parallel'
```
In the above example, one can increase the number of *nodes* and/or *ntasks* if needed and combine it
with `--exclusive` whenever needed. In general, **no hypertheading** is recommended for MPI based jobs.
Also, one can combine it with `--exclusive` when necessary.
Also, one can combine it with `--exclusive` when necessary. Finally, one can change the MPI technology in `-start-method`
(check CFX documentation for possible values).
