Slurm is an open source, fault-tolerant, and highly scalable cluster management and job scheduling system for large and small Linux clusters. It has been used in many supercomputing sites and data centers across the world. JLab farm deployed Slurm in early 2019, but it was hidden from users by Auger system. Users now can access Slurm directly from farm interactive nodes.
Submitting Batch Jobs
You can submit jobs from one of the
interactive nodes or from within a running batch script. Batch jobs are
submitted using slurm
sbatch commands with a valid project account. You can
specify options on the command line, or (recommended) put all of them
into your batch script file. See examples below. In your batch script, please specify at least the following, plus other options useful to your workflow.
- account (your project short name), using -A, --account=<account>
- partition (like pbs queue) , using -p, --partition=<partition_names>
- resources needed (number of nodes, mode of nodes, etc), using -C, --constraint=<list>, -N, --nodes=<num_node> or -n, --ntasks=<num_core>
- wall time (specifying this more tightly than the default will improve your throughput), using -t, --time=<time>
Right now there are three partitions, general, production and priority, are configured. Please use
Scicomp portal Job page for the status of active and recently finished jobs, as well as the most current partition information.
