Core Areas

What is HPC?

HPC is all about modern, innovative IT infrastructures for complex and parallel simulations as well as for analysis and processing of large volumes of data.


Hardware is the technical basis for digital analysis, computation and visualisation of data. Examples are processors, memory and networks.


HPC Innovation

Software supports scientists as well as companies to model and solve complex tasks and problems in a variety of areas.



The Gauß-Allianz offers support and solutions for performant, scalable and parallel software and hardware especially for small and medium entreprises.

HPC-driven innovation

Many everyday problems in science and technology need the power of high performance computing to develop innovative solutions and discover new insights.
