+Besides replacing the `srun` command you need to be aware that **MUST always allocates an extra

 This is usually not critical, however in batch jobs **make sure to allocate an extra CPU for this
 task**.
 
 Finally, MUST assumes that your application may crash at any time. To still gather correctness
 results under this assumption is extremely expensive in terms of performance overheads. Thus, if
