OAR

The oar executor runs pipeline tasks using the OAR resource manager. It submits each task as an OAR job using the oarsub command.

To enable the OAR executor, set process.executor = 'oar' in the nextflow.config file. Launch the pipeline from a node where oarsub is available, typically the cluster login node.

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

• clusterOptions
• cpus
• memory
• queue
• time

When you specify clusterOptions as a string, separate multiple options with semicolons so that the job script is formatted correctly:

clusterOptions = '-t besteffort;--project myproject'

Added in version 24.04

You can also specify the options as a string list:

clusterOptions = [ '-t besteffort', '--project myproject' ]

See clusterOptions for details.
