Scientific computing

Welcome to the pages of the"Scientific Computing" service of the ZIMT.

The Center for Information and Media Technology operates the OMNI cluster and a number of other computing systems to enable scientists at the University of Siegen to perform scientific computing. The use of these systems is generally free of charge for university members.

If you would like to compute on one of our systems yourself or are looking for advice on scientific computing, please contact us at hpc-support@uni-siegen.de
or come to our office hours.

OMNI Cluster

OMNI cluster

The OMNI cluster at the University of Siegen is the central resource for high-performance computing (HPC), data science and all other tasks in the field of scientific computing. It is by far the largest system.

The cluster is used, for example, for calculations in the fields of computational fluid dynamics, finite element methods and chemical simulations. However, it is also designed for other applications (e.g. Tensorflow and Pytorch from the field of big data).

The OMNI cluster consists of a total of 439 nodes, each with 64 cores and 256 GB RAM, as well as additional nodes for various tasks, including GPU nodes. A total of 500 TB of hard disk space is available. The peak performance is around 1044 TFlops.

The installed operating system is Rocky Linux.
