Gottfried and Konrad in the Top 500

Namesakes for the HLRN-III complexes revealed

With the Berlin HLRN-III complex being already in user operation and the Hannover complex being in the acceptance phase, HLRN has revealed the names of the systems: Konrad in Berlin, and Gottfried in Hannover.

About the namesakes of HLRN-III

Gottfried Wilhelm Leibniz [1], born in Leipzig in 1646, is the namesake of the Hannover installation site Leibniz University Hannover. He was a prominent German mathematician, philosopher, physicist and statesman. Noted for his independent invention of the differential and integral calculus, Gottfried Leibniz remains one of the greatest and most influential metaphysicians, thinkers and logicians in history. Leibniz also discovered the binary number system and invented the first calculating machine that could add, subtract, multiply and divide. He also invented the Leibniz wheel and suggested important theories about force, energy and time. He died in Hannover in 1716 at the age of 70.

Konrad Zuse [2], born in Berlin in 1910, is the namesake of the Berlin installation site Konrad-Zuse-Zentrum für Informationstechnik Berlin (ZIB). After completing school he studied civil engineering and architecture at the predecessor of today’s Technical University Berlin. With the Z3, he developed the world’s first functional freely programmable computer. Between 1945 and 1947, Konrad Zuse also developed Plankalkül, the world’s first object-oriented programming language. After World War II, he founded his own company, the Zuse KG. After he retired, he increasingly dedicated himself to his second passion: the art of painting. Konrad Zuse died in 1995 at the age of 85 in Hünfeld near Fulda.

The HLRN-III in the Top500 list

Konrad and Gottfried are the Cray XC30 systems for the first installation phase of the HLRN-III project. The systems went online just in time to be included in the 42nd Top500 List, released on November 18th, 2013. The complexes entered the list at ranks no. 120 and 121, with a Linpack benchmark performance of 295.7 TFlops/s each.

The full installation was finished by the end of 2014 where the complexes entered the list at ranks no. 51 (Konrad) and 61 (Gottfried), with a Linpack benchmark performance of 991.5 TFlops and 829.8 TFlops, respectively.
