# PBS Pro

The `pbspro` executor runs pipeline tasks using the [PBS Pro](https://www.pbspro.org/) resource manager. It submits each task as a PBS Pro job using the `qsub` command.

To enable the PBS Pro executor, set `process.executor = 'pbspro'` in the `nextflow.config` file. Launch the pipeline from a node where `qsub` is available, typically the cluster login node.

Use the following process directives to control resource requests and other job characteristics:

- [clusterOptions][process-clusteroptions]
- [cpus][process-cpus]
- [memory][process-memory]
- [queue][process-queue]
- [time][process-time]

[process-clusteroptions]: ../reference/process#clusteroptions
[process-cpus]: ../reference/process#cpus
[process-memory]: ../reference/process#memory
[process-queue]: ../reference/process#queue
[process-time]: ../reference/process#time
