Infinite Storage
Infinite Possibilities
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 HPS group is tightly integrated into the GWDG AG Computing group with more than 25 people.
