UiB operates supercomputer facilities that serve the high-end computational needs of scientists at Norwegian universities and other national research and industrial organizations. Additionally, the system is used for research and development by international organizations and provides services to European research groups (and projects) as well as to cooperating scientists from international institutions.

The installations are funded by the Norwegian Research Council through the NOTUR project, the University of Bergen (UiB), the Nansen Environmental and Remote Sensing Center (NERSC), the Institute for Marine Research (IMR), and Uni Research AS. These partners make critical use of the system for scientific research and development, in particular targeting marine activities ranging from marine molecular biology to the large scale simulation of ocean processes including the management of ocean resources and monitoring of the environment. Heavy use by academic research groups has traditionally come from computational chemistry, computational physics, computational biology, the geosciences, and applied mathematics. Sigma2 is an umbrella organisation which coordinates these efforts. Please refer to Sigma2 website for details.

In addition to the National infrastructure UiB has local facilities to cover smaller needs of the University. The local facility is installed at the High Technology Center in Bergen (HiB) and is managed and operated by UiB IT department. Current installation:
