Introduction
The WWU IT is providing HPC resources to aid researchers conduct computationally demanding tasks. For this purpose we are hosting the PALMA-II HPC cluster. It is meant to be used to run applications which are highly parallelized and can take advantage of hundreds or thousands of cores simultaneously and/or need very large amounts of memory.
The HPC team is maintaining the cluster and trying to keep it operational 24/7. We are also providing a default set of software to use on the cluster and try our best to help with installing or optimizing programs you want to run. However, time is limited and sometimes the applications you want to run on the cluster might just not be suited for this use-case. Please inform yourself about what resources you require and if you can actually make use of an HPC cluster.
What HPC is not
The cluster is not a very fast computer replacing your laptop or workstation. Programs on HPC clusters, normally, do not make use of any GUI and calculations are typically submitted via so called job scripts. Users should be familiar with the Linux command line and should thoroughly read the information provided in this wiki.

CALCULATIONS ON THE LOGIN NODE ARE NOT ALLOWED!
The login node of PALMA is not a place to start any serious calculations nor is it a playground for testing purposes or compiling programs! Any user processes violating this rule will be terminated immediately without any warning!

Requirements
- Register your research group for the usage of the HPC resources.
This has to be done only once per research group. The application can be found on the right. A quick reference card guiding you through the steps of your application can also be found on the right.
- Register for the group u0clstr at the IT Portal and accept our Terms of Use.
- Register at our HPC mailing list
- Read the how-to guides provided on this website
Application
Quick-Reference-Card
After registering it can take up to 24h until you can login at PALMA-II!
Publications
We kindly ask you to record any publication you made with the help of our HPC systems at CRIS.WWU with an appropriate note. Instructions can be found here.
Lectures
Once a semester there is a lecture about parallel programming and the usage of our HPC system. This lecture is intended for people with prior knowledge in Linux and C/C++ or Fortran programming. It is not an introductory course, however, if you just want to inform yourself on the basic usage of PALMA-II, you are welcome to join the first day of this lecture.
