Submitting a Job with SLURM The workload manager adopted in the COKA cluster is SLURM. The suggested way to submit a job using SLURM is to prepare a Job submission file, also known as job file or submission script. The main purpose of this file is to ask for resources from the job scheduler and to indicate the program to be run. It can be used also to set environment variables, compile your code, etc.

Available Hardware The COKA Cluster is made up of one master node acting as a login front-end and 4 compute nodes named: node01, node02, node03, node04 In the compute nodes hyper-threading is disabled, although it is enabled in the login node. The computing hardware of one node can be summarized by this schema:
