Foundation of ZAIK

  • Grown from a merger of the University`s Regional Computing Center (RRZK) and its Center for Parallel Computing (ZPR), the Zentrum für Angewandte Informatik der Universität zu Köln/ZAIK (Center for Applied Computer Science of the University of Cologne) is a central institution of the University of Cologne.
  • It coordinates service, research and teaching activities in the area of information processing throughout the University.
  • The Campus-Wide Services group ("Universitätsweiter Service") of the ZAIK corresponds to the former RRZK.
  • Close cooperation with all computer science related departments of the university is considered a vital ingredient of ZAIK`s mission.
