  • Slurm Job Manager

    Overview Rivanna is a multi-user, managed environment. It is divided into login nodes (also called frontends), which are directly accessible by users, and compute nodes, which must be accessed through the resource manager. Users prepare their computational workloads, called jobs, on the login nodes and submit them to the job controller, a component of the resource manager that runs on login nodes and is responsible for scheduling jobs and monitoring the status of the compute nodes. We use Slurm, an open-source tool that manages jobs for Linux clusters. Jobs are submitted to the Slurm controller, which queues them until the system is ready to run them.
