The new high-performance computer of the Karlsruhe Institute of Technology (KIT) is among the 15 fastest computers in Europe. The “Hochleistungsrechner Karlsruhe“ ranks 53rd on the biannual Top 500 list of the world’s fastest computers. In terms of energy efficiency, it even makes the 13th place in the international supercomputer ranking.

“In science, high-performance computers crucially contribute to finding fast solutions to our most pressing challenges: This applies to energy and climate research as well as to research for sustainable mobility, and also to materials science and medicine,” says KIT President Professor Holger Hanselka. “The excellent ranking of HoreKa in the current Top 500 list impressively shows that we at KIT are very well equipped for these tasks with one of the most powerful and at the same time most energy-efficient supercomputers in Europe.”

“Only a computer that makes it onto this list is considered a real supercomputer”, explains Dr. Jennifer Buchmüller, Head of High Performance Computing at KIT’s Steinbuch Centre for Computing (SCC). “In order to place HoreKa on the list, its computing power had to be measured with a special benchmark application – the so-called High Performance LINPACK,” Buchmüller says. This benchmark lets the computing units solve a very large system of matematical equations, the time required to complete this process indicates how fast a system is.

Two innovative chip technologies – one high-performance system.

Unlike most other supercomputers, HoreKa is a hybrid system that consists of two very different modules. “HoreKa-Green” comprises the part with computing accelerators based on graphics processors (GPUs), “Horeka-Blue” the one with standard processors (CPUs). The accelerator chips from NVIDIA achieve extremely high performance for certain computing operations that are very important for science, such as solving systems of equations or simulating neural networks in artificial intelligence. For other operations, however, the standard processors from Intel are much better suited. The strengths of both architectures are then combined to achieve the maximum performance.

The system therefore appears twice in the June edition of the Top500 list: 53rd with 8 PetaFLOPS and a second time 220th with 2.33 petaFLOPS. One petaFLOPS corresponds to a performance of one quadrillion computing operations per second, comparable to the performance of around 8,000 laptops. Overall, HoreKa can even deliver a peak performance of 17 PetaFLOPS, which is roughly equivalent to the performance of around 150,000 laptops and would theoretically mean an even higher ranking. “However, the scoring of hybrid systems like HoreKa is not provided for by the benchmark application on which the Top500 list is based,” says Buchmüller.

Fast computers are an indispensable part of science

“The faster high-performance computers solve mathematical equations and process data, the more detailed and reliable the simulations are that can be produced using them,” Buchmüller explains. “Consequently, in many scientific disciplines such as Earth System and Climate Sciences, Materials Research, Particle Physics and Engineering, supercomputers have become an indispensable part of researchers’ daily work.”

Also world-class in energy efficiency

Supercomputers require a lot of energy, but it is used much more efficiently than by conventional PCs and laptops. HoreKa also tops in energy efficiency and is currently ranked 13th on the “Green500” list of the most energy-efficient supercomputers in the world. “The highly energy-efficient hot water cooling system allows us to cool the supercomputer with minimal energy use year-round. In the colder months, the office space can also be heated using the waste heat.”

Official inauguration in July

The official inauguration ceremony with the handover to the scientific communities is on Friday, July 30. An invitation to the press event will follow separately.

The system is available to scientists from all over Germany. Thanks to the new supercomputer, researchers in the areas of Earth System Sciences, the Materials Sciences, Energy and Mobility research in Engineering and Particle Physics will be able to gain a more detailed understanding of highly complex natural and technical processes.

Mission Statement of KIT


Karlsruhe Institute of Technology-KIT [Karlsruher Institut für Technologie] (DE) was established by the merger of the Forschungszentrum Karlsruhe GmbH and the Universität Karlsruhe on October 01, 2009. KIT combines the tasks of a university of the state of Baden-Württemberg with those of a research center of the Helmholtz Association of German Research Centres [Helmholtz-Gemeinschaft Deutscher Forschungszentren] (DE) in the areas of research, teaching, and innovation.

The KIT merger represents the consistent continuation of a long-standing close cooperation of two research and education institutions rich in tradition. The University of Karlsruhe was founded in 1825 as a Polytechnical School and has developed to a modern location of research and education in natural sciences, engineering, economics, social sciences, and the humanities, which is organized in eleven departments. The Karlsruhe Research Center was founded in 1956 as the Nuclear Reactor Construction and Operation Company and has turned into a multidisciplinary large-scale research center of the Helmholtz Association, which conducts research under eleven scientific and engineering programs.

Being “The Research University in the Helmholtz Association”, KIT creates and imparts knowledge for the society and the environment. It is the objective to make significant contributions to the global challenges in the fields of energy, mobility, and information. For this, about 9,300 employees cooperate in a broad range of disciplines in natural sciences, engineering sciences, economics, and the humanities and social sciences. KIT prepares its 24,400 students for responsible tasks in society, industry, and science by offering research-based study programs. Innovation efforts at KIT build a bridge between important scientific findings and their application for the benefit of society, economic prosperity, and the preservation of our natural basis of life. KIT is one of the German universities of excellence.

In 2014/15, KIT concentrated on an overarching strategy process to further develop its corporate strategy. This mission statement as the result of a participative process was the first element to be incorporated in the strategy process.

Mission Statement of KIT
KIT combines the traditions of a renowned technical university and a major large-scale research institution in a very unique way. In research and education, KIT assumes responsibility for contributing to the sustainable solution of the grand challenges that face the society, industry, and the environment. For this purpose, KIT uses its financial and human resources with maximum efficiency. The scientists of KIT communicate the contents and results of their work to society.

Engineering sciences, natural sciences, the humanities, and social sciences make up the scope of subjects covered by KIT. In high interdisciplinary interaction, scientists of these disciplines study topics extending from the fundamentals to application and from the development of new technologies to the reflection of the relationship between man and technology. For this to be accomplished in the best possible way, KIT’s research covers the complete range from fundamental research to close-to-industry, applied research and from small research partnerships to long-term large-scale research projects. Scientific sincerity and the striving for excellence are the basic principles of our activities.
