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.

Overhead is drastically reduced with this switch. ### Result Files -- GitLab
