The team Scientific IT Systems is part of the department of Technical and Administrative Infrastructure (PGI/JCNS-TA). The staff supports researchers at researchers at Peter Grünberg Institute (PGI), Jülich Centre for Neutron Science (JCNS), Institute of Complex Systems (ICS), Institute for Advanced Simulation (IAS), Institute of Biological Information Processing (IBI) and Ernst Ruska Centre (ER-C) with IT-technical problems and both plan and operate highly available server and storage systems for the HPC-Cluster and scientific desktop computers. Also part of the core tasks are optimization of programs for special processor architectures and the development of dedicated controlling and visualization systems for experiment and process data processing.
