# Slurm Diamond Workflow

In this tutorial you will learn how to run a workflow on an HPC that uses the `Slurm` scheduler
with these torc features:

- Job dependencies based on input and output files
- Jobs with different compute node requirements
- Delayed compute node scheduling

The workflow is a derivation of the {ref}`diamond-workflow`. Follow the same steps except for these
deviations:

1. Use the workflow specification file [examples/slurm_diamond_workflow.json5](https://github.com/NREL/torc/blob/main/examples/slurm_diamond_workflow.json5).
2. Change the Slurm account name.
3. Configure and start the workflow from an HPC login node.
4. Instead of `torc jobs run`, schedule a compute node to run the jobs with

```console
$ torc hpc slurm schedule-nodes -n 1
```

Torc will schedule the second node with GPUs when the postprocess script is ready to run.
