High-Performance Storage

The research group High-Performance Storage improves the capabilities of storage landscapes applying smart concepts. We speak big data analytics and high-performance computing and apply our knowledge to meet the needs of environmental modeling.

Further information about our mission.

The virtual research group connects members from the GWDG, the Department of Computer Science of the University of Reading, and the Scientific Computing Group of the University of Hamburg.
