Supercomputers

Supercomputers have been established as indispensable tools in science. Computer simulations open the door to advances not possible via the conventional route of theory and experimentation. For instance, simulations on supercomputers are needed to validate scientific models in physics, climate research or neuroscience. At the same time, they provide new insights into the properties and structure of materials and biomolecules, as well as the sequence of biological and chemical processes.

The Forschungszentrum Jülich has been the leading location for supercomputers in Europe since the establishment of the first German high-performance computing centre in 1987. The Jülich Supercomputing Centre runs computers in the highest performance category, including the JUQUEEN and JURECA supercomputers, which are currently among the most powerful in the world with a computing power of over five petaflop per second.

JURECA and JUQUEEN's successor – to be installed in 2018 – have an innovative modular supercomputing architecture tailored to today's scientific computing needs. This modular architecture does not stipulate a standardised structure; rather, the different modules specialise in specific tasks such as highly parallel computing or scientific Big Data analysis, and can be controlled via a single user interface.

Experts from the JSC have developed the concept with partners from other institutions and companies with a view to developing the next generation of supercomputers, known as the Exascale class.

Computing time on Jülich's supercomputers is granted through an independent peer review process conducted by the John von Neumann Institute for Computing. The Jülich Supercomputing Centre is a co-founder of the Gauss Centre for Supercomputing (GCS) – which combines Germany's three high-performance computing centres – and the coordinator of the European supercomputer network PRACE.
