High Performance Computing

Our department offers advice on the topic of High Performance Computing (HPC) and compute clusters.

Current State of the Tier3 HPC-Cluster

The Ruhr-University Bochum selected MEGWARE as partner for constructing the new Tier-3 HPC-Cluster. It is expected to begin operation in the third quarter of 2024. The cluster will consist of four kinds of nodes to reflect the heterogeneous requirements of our researchers. 

Nodes specifications:

Kind Amount CPUs Memory Local NVMe Storage GPU
Thin-CPU 284 2xAMD EPYC 9254 (24 core) 384 GB 960 GB -
Fat-CPU 13 2xAMD EPYC 9454 (48 core) 2304 GB 1.92 TB -
Thin-GPU 20 2xAMD EPYC 9254 (24 core) 384 GB 1.92 TB 3xNVIDIA A30 Tensor Core GPU 24GB, 933GB/s
Fat-GPU 7 2xAMD EPYC 9454 (48 core) 1152GB 1.92 TB + 15.36 TB 8xNVIDIA H100 SXM5 GPUs 80GB, 3.35TB/s


All nodes will be connected via an Omni-Path network to enable efficient execution of multinode computations. A mass storage of 1.5PB will be available to store research data. For lot term storage of data the cluster will be connected to the already established research data storage.

Access to the cluster is granted to all research groups located at the Ruhr-University. Usage will be free of charge. More information on the application process will be announced in the second quarter of 2024.

Application of external HPC-Resources

The HPC resources in Germany are arranged hierarchically in the so-called HPC pyramid.


Scientists of German teaching and research institutions should, if suitable for their needs, use their local resources provided by the tier-3 centres. If you need more resources than your centre can provide, you do not have a local HPC centre, or your project requires specialized hardware (e.g. larger memory, more cores, GPUs, etc.), you are welcome to contact another HPC centre or request computing time at a higher tier (tier-2 or tier-1).

State-wide Computing Resources (Tier-2, Tier-3)

Several state-wide tier-2 centres (NHR centres) are available to cater for specialized computing and/or storage requirements. In North Rhine-Westphalia, the RTWH Aachen, the University of Cologne and the University of Paderborn offer structured access to HPC users from NRW institutes.

National and EU-wide HPC-Resources (Tier-1 and Tier-0)

For extremely complex and data-intensive requirements, HPC resources of the highest tier are available in Germany and the EU. Computing time is only allocated after a technical and scientific peer review process (GCS, PRACE). We would be happy to advise you on the suitability of your projects for HPC as well as provide help with the application process for all levels of the HPC pyramid.


The Ruhr-University of Bochum is part of the North Rhine-Westphalian Competence Network for High Performance Computing HPC.NRW. This network offers a first point of contact and central advisory hub with a broad knowledge base for HPC users in NRW. In addition, the tier-2 centres offer uniform, structured access for HPC users of all universities in NRW, ensuring basic services are provided for locations without tier-3 centres and for Universities of Applied Sciences.

A network of thematic clusters for low-threshold training, consulting and coaching services has been created within the framework of HPC.NRW. The aim is to make effective and efficient use of high-performance computing and storage facilities and to support scientific researchers of all levels. The existing resources and services that the state has to offer are also presented in a transparent way.
