 You might also need to specify a **reservation** by adding the flag `--reservation=<name-of-reservation>`.
 For the 2022 PDC Summer School the reservation name is ``summer-<date>``, where ``date`` is to be provided in the format ``YYYY-MM-DD``, e.g. ``summer-2022-08-16``.

 For this exercise you should compare different setups where (a) both MPI ranks are on the same node, e.g.
 
 ```
