==Usage of the SLURM scheduler ==
Website: http://slurm.schedmd.com
The schedule of the HPCs are CPU hour based. This means that the available core hours are divided between users on a monthly basis. All UNIX users are connected to one or more account. This scheduler account is connected to an HPC project and a UNIX group. HPC jobs can only be sent by using one of the accounts. The core hours are calculated by the multiplication of wall time (time spent running the job) and the CPU cores requested.
</pre>
where <code>ACCOUNT</code> is the name of the account to use (available accounts can be retrieved with the <code>sbalance</code> command), <code>NAME</code> is the short name of the job, <code>TIME</code> is the maximum walltime using <code>DD-HH:MM:SS</code> syntax. Acceptable time formats include "minutes", "minutes:seconds", "hours:minutes:seconds", "days-hours", "days-hours:minutes" and "days-hours:minutes:seconds".
The following command submit jobs:
${MAPLE}/toolbox/Grid/bin/joblauncher ${MAPLE}/toolbox/Grid/samples/Simple.mpl
</pre>
==== GPU compute nodes ====
The Szeged site accomodates 2 GPU enabled compute nodes. Each GPU node has 6 Nvidia Tesla M2070 cards. The GPU nodes reside in a separate job queue (<code>--partition gpu</code>). To specify the number of GPUs set <code>--gres gpu:#</code> directive.
===== Example =====
Alice user submits to the foobar account a 4 GPU, 6 hour job.
<pre>
#!/bin/bash
#SBATCH -A foobar
#SBATCH --job-name=GPU
#SBATCH --partition gpu
#SBATCH --gres gpu:4
#SBATCH --time=06:00:00
$PWD/gpu_burnout 3600

== Extensions ==
Extensions should be asked for at the Execution site (NIIF) at prace-support@niif.hu. All requests will be carefully reviewed and decided if eligable.
== Reporting after finishing project ==
A report must be created after using PRACE resources. Please contact prace-support@niif.hu for further details.
