Scientific Computing

This scientific service unit supports scientists for any scientific computing needs they may have.

Its staff operates a High-Performance Computing (HPC) Cluster and provides procurement and licensing services for scientific software.

They are also in contact with the VSC, the cluster for academic and research institutes in Austria, for which they can provide access to resources and support.
