Computer Simulation with Supercomputers

Computer simulations have become the third pillar of research alongside theory and experiment, providing us with insights that had long remained concealed for physical, technical or financial reasons. Almost all research areas benefit from simulations: from medical science to engineering sciences, information technology and material sciences up to environmental and energy research. Many simulations, however, require the massive computing power of supercomputers. 

Scientists of the section JARA-HPC (short for High-Performance Computing) combine the knowledge of massively parallel computing on supercomputers with the respective expert research competences, e.g. of medical scientists or engineers.

In this way, they considerably contribute to making full use of the opportunities offered by computer simulations to address current research issues. A unique organizational structure supports the scientists in this undertaking, consisting of so-called Simulation Laboratories and Cross-Sectional Groups.

JARA-HPC researchers have already used simulations to improve blood pumps that assist the heart of critically ill patients, and they created a "virtual brain" to help brain researchers explore and understand the interconnections within the human brain in more detail. Other scientists calculated unusual magnetic and electronic properties of materials and thus gained information that helped them to construct novel electronic devices and data storage systems. Last but not least, JARA-HPC researchers developed computer simulations that can be used to predict how human activities impact on the diversity of species in meadows and pastures of the Eifel National Park


Scientists of the section HPC furthermore have access to the world's most powerful supercomputers, in particular via the Jülich Supercomputing Centre (JSC) of Forschungszentrum Jülich. The researchers develop application software that is keeping pace with the increasing power of supercomputers.

As part of a cooperation project between RWTH Aachen University and Forschungszentrum Jülich (JARA), a new database was created, that provides comprehensive overview of the main research areas in energy of the two institutions.
