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 supply the following information:

1. Your ZEDAT account username
2. The group you are using the system for (e.g. ag-netz,ag-imhof,…)
3. The software you are using for your simulations (e.g. gromacs, gaussian, self-written code in language XYZ, …) and whether you use MPI or OpenCL/CUDA.
4. Software that you happen to know so well that other HPC users within the department may ask you for help.
5. A self contained job example that is typical for the workload you are using the HPC systems for, ideally with a small README describing how to run it and a job script. If possible scale it so it runs between a few minutes and an hour at maximum.
6. If you are no longer a member of the physics department, we would like to get an estimate on how much longer you will need access to the systems (e.g. to finish some paper)

2018-06-28: Currently there are three HPC clusters in production at the physics department. One cluster (“leonard”) is located in the HLRN datacenter, another (“yoshi”) is located at ZEDAT and the third (“tron”) in located in the IMP datacenter at Takustraße 9. See the table below for further information on available resources. The yoshi cluster is currently under maintenance for upgrade of the system.

• Important notes on cluster usage
• Start with the Introduction to the Slurm HPC cluster.
• Using interactive sessions with the queuing system.
• How to make use of the GPU-nodes.
• Here is a list of special nodes that are currently not part of slurm.
• Here is a list of HPC users and the software they use

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

The following table lists some HPC resources available at the physics department. At the end of the table we also list the resources for the ZEDAT soroban cluster. The tron cluster at Takustrasse 9 is currently restructured. We also have some special purpose nodes that are currently not managed by Slurm.
