# Tips, tricks, FAQ

All the little things to save you time on the clusters

## Deleting `model_output/` (or any big folder) is too long on the cluster

Yes, it takes ages because IO can be so slow, and there are many small files. If you are in a hurry, you can do

```bash
mv model_output/ model_output_old
rm -r model_output_old &
```

The first command rename/move `model_output`, it is instantaneous. You can now re-run something. To delete the renamed folder, run the second command. the `&` at the end makes it execute in the background.

## Use `seff` to analyze a job

After a job has run (either to completion or got terminated/fail), you may run:

```bash
seff JOB_ID
```

to know how much ressources your job used in your node, what was the cause for termination and so on. If you don't remember the `JOB_ID`, look for the number in the filename of the slurm log (`slurm_{JOB_ID}.out`).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://iddynamics.gitbook.io/flepimop/how-to-run/tips-tricks-faq.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
