## Tips
## Recommendations on run configuration

### Disabling core-dumps

If a large job crashes and tries to write core-dump files on thousands of processes,
it will overwhelm the filesystem. Therefore we strongly recommend to disable them with
the following command:

``` console title="disable writing of core-dump files"
$ ulimit -S -c0
```

### Improving job startup times
