apps.crc_interactive

A simple wrapper around the Slurm srun command.

The application launches users into an interactive Slurm session on a user-selected cluster and (if specified) partition. Dedicated command line options for selecting specific clusters.

Each cluster is provided with predefined command line options. As a result, this application does support dynamic cluster discovery. New clusters need to be manually added (or removed) by updating the application CLI arguments.
