====== Information about the HPC-Cluster ======

In order to get access to the department of physics HPC resources you need to send an email to hpc@physik.fu-berlin.de. Please give some information on the kind of jobs you are planing to run and software you plan to use, if possible.

**2015-06-16**: Currently there are two HPC clusters in production at the physics department. One is located in the HLRN datacenter, the other is located at ZEDAT. See the table below for further information on available resources. Both cluster only share a common /home. Everything else like the queuing system ot /scratch are distinct. Both are running Debian/Wheezy and utilize the Slurm scheduling system. 

===== Slurm documentation =====

  * [[important|Important notes]] on cluster usage
  * Start with the [[slurm|Introduction to the Slurm HPC cluster]].
  * Using [[interactivesessions|interactive sessions]] with the queuing system.
  * How to make use of the [[gpunodes|GPU-nodes]].

===== General documentation =====

  * Robert Hübener from AG-Eisert has written a HOWTO for using [[mmacluster|Mathematica on a HPC-Cluster]].
  * A current python version has been built for cluster usage. The [[pythoncluster|Python on the HPC-Cluster]] tutorial describes how to set it up.
  * Try to [[usetmpforio|use /tmp for I/O intensive single node jobs]]

===== Overview of available resources =====

The following table lists all HPC resources available at the physics department. At the end of the table we also list the resources for the ZEDAT [[http://www.zedat.fu-berlin.de/HPC/Soroban|soroban]] cluster. The tron cluster at Takustrasse 9 is currently restructured and will most likely start running Debian/Jessie.
