It's possible to create a shh tunel tunnel to Clariden via Ela. The following must be add in your personal computer's ~/.ssh/config file (replacing <username> by your CSCS user name)

  • Clariden uses the Slurm  workload manager to manage the job scheduling.

  • Some typical/helpful slurm commands are

    sbatch
    		submit a batch script
    squeue
    		check the status of jobs on the system
    scancel
    		delete one of your jobs from the queue
    srunlaunch commands in an existing allocation
    srun --interactive --jobid <jobid> --pty bash
    		start interactive session on an allocated node


  • Example of Slurm job script

    Code Block
    languagebash
    #!/bin/bash -l

#SBATCH --job-name=<jobname>
#SBATCH --time=00:15:00
#SBATCH --nodes=1
#SBATCH --ntasks-per-core=1
#SBATCH --ntasks-per-node=4
#SBATCH --cpus-per-task=16
#SBATCH --partition=nvdgpu
#SBATCH --account=<project>

srun executable
    Currently there's no accounting of the compute time, but it's expected to be setup.

  • Please note that the Slurm scheduling system is a shared resource that can handle a limited amount of batch jobs and interactive commands simultaneously. Therefore users are not supposed to submit arbitrary amounts of Slurm jobs and commands at the same time.
