The University of Siegen 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.
