One can enable hypertheading by defining `--hint=multithread`, `--cpus-per-task=2` and `--ntasks-per-core=2`.
However, this is in general not recommended, unless one can ensure that can be beneficial.
#### MPI-based example
An example for running Fluent using a Slurm batch script is the following:

In the above example, one can increase the number of *nodes* and/or *ntasks* if needed. One can remove
`--nodes`` for running on multiple nodes, but may lead to communication overhead.
