==== Access and usage of the IGBMC HPC cluster ====


First you need to verify that your environment is properly set.

<code>>ssh login@surf</code>

The sbatch command allow you to submit a script with commands to the cluster

<code>>sbatch -p surf cmd</code>

  * The command then gives a job execution number.
  * <q>>scontrol show job <job-number></q> allows you to follow the execution of the job
  * <q>>scancel <job-number></q> allows you to kill the job

The job will generate output files:
  * //slurm-<job-number>.out// in the directory from which the sbatch command was executed
  * //slurm-<job-number>.e// in case of errors

In case of necessity the debug line <q>sbatch -p debug</q> allows you to use two additional lames (16 procs with 24GB memory)

There are options to:
  * specify the memory required <q>>sbatch -p surf --mem=xxMB</q>
  * specify the number of processors required <q>>sbatch -p surf --cpus--per-task=24</q> (if you specify more than 24, the number of available lames for your job will be very limited)



The cmd script must start with <code>#!/bin/bash</code> and should set the necessary environement.
All alias can be checked with the command <q>>alias</q>
