Usage on Owens
Set-up
To load the default Nextflow library, run the following command: module load nextflow. To load a particular version, use module load nextflow/version. For example, use module load nextflow/21.10.3 to load Nextflow version 21.10.3. You can use module spider nextflow to view available modules.
Batch Usage
When you log into owens.osc.edu you are actually logged into a linux box referred to as the login node. To gain access to the mutiple processors in the computing environment, you must submit your job to the batch system for execution. Batch jobs can request mutiple nodes/cores and compute time up to the limits of the OSC systems. Refer to Queues and Reservations and Batch Limit Rules for more info.
