From 2013 to 2018 the compute systems of the HLRN-III had been installed at the compute sites Zuse Institute Berlin (ZIB) and Leibniz Universität IT Services (LUIS/RRZN at university Hannover).
The compute systems of the HLRN-III hold the names Konrad (for Konrad Zuse, siehe Bild links) at ZIB and Gottfried (nach Gottfried Wilhelm Leibniz, siehe Bild rechts) at LUIS.
Each complex runs a Cray XC30/XC40 system for massively parallel processing (MPP) and several servers for special purposes. In Hannover, an additional compute system is available for symmetric multiprocessing (SMP) applications with high memory and local disk I/O demands. In Berlin, a separate Cray Test & Development System (TDS) is operated for the evaluation of new technologies, including Intel Xeon Phi many-core processors and SSD based storage devices.
Starting with the HLRN-III first installation phase, four Cray XC30 racks equipped with Intel Xeon IvyBridge processors were set up each at ZIB and RRZN. For the HLRN-III second installation phase, the complexes at ZIB and RRZN were substantially extended with six and five additional Cray XC40 racks, respectively, equipped with Intel Xeon Haswell processors.

The SMP system was composed of the components SMP1 and SMP2 (installation phases 1 and 2) from the company MEGWARE, holding Intel Xeon processors.
The test and development system was dedicated to the evaluation of new technologies. It was equipped with Intel Xeon Phi precessors and SSD storage devices. TDS was open for all HLRN users, in particular for code developers.
