The ForHLR II high-performance research computer

In spring 2012, the application by the state of Baden-Württemberg and KIT for the procurement of a high-performance research computer (ForHLR) was approved.


The procurement took place in two phases:

Phase 1 included a computer (ForHLR I) with a global file system; installation took place in mid-2014 in the computer rooms of the South Campus. The ForHLR I cluster was decommissioned in April 2020. ForHLR II was shut down one year later.


Phase 2 consists of the components buildings, computers, file systems and visualization systems. ForHLR II was set up in a newly constructed building on Campus North.

Prof. Peter Gumbsch (Institute Director at KIT and at the Fraunhofer-Gesellschaft in Freiburg), Prof. Holger Hanselka (President of KIT), Minister Theresia Bauer and Prof. Bernhard Neumair (Managing Director of the SCC) switch on the ForHLR II.


The second stage of the ForHLR high-performance research computer was put into operation together with a new computer building and a new visualization room on 4 March 2016 by Baden-Württemberg's Minister of Science Theresia Bauer and the President of KIT, Holger Hanselka, during a ceremony and colloquium.


The ForHLR (Phase) II high-performance research computer, which is jointly funded by the state of Baden-Württemberg and the federal government, has been in productive use by scientists since April 20, 2016. The cluster was shut down in April 2021.


The ForHLR II was a parallel computer equipped with Intel Xeon processors with more than 24,000 cores.


The allocation of computing time on the ForHLR II was based on project applications, which are reviewed by a steering committee.



The ForHLR II high-performance computer enabled scientists from all over Germany to work on complex application problems.
problems. As a parallel computer of performance class 2, it was positioned below the systems of the national supercomputing centers and above the university clusters.
centers and above the university cluster systems and was therefore suitable for application problems that require processor numbers from the mid
3-digit and 4-digit range.

Rendering nodes and projection rooms are available for the visualization of simulation results and data in the North Campus at the SCC
are available. There are special visualization computers and various special devices for method research and tool development
such as 3D scanners at the IVD.
