TU Darmstadt inaugurates Lichtenberg II high-performance computer
News expansion sets standards in performance and energy efficiency
2023/07/12
On 11 July 2023, the TU Darmstadt officially inaugurated the new Lichtenberg II high-performance computer. Data from Clean Circles for calculating the CO2-free cycle for storing and transporting renewable energies to Europe in iron will also be analysed via the new Lichtenberg II system.
In mid-2020, the first expansion stage of the Lichtenberg II with 643 computing nodes was put into operation; this will now be expanded by 581 computing nodes with the second expansion stage. Together, the two expansion stages will provide their users with a theoretical peak performance of approximately 8.5 petaflops (PFlops) per second through processors and 1.7 petaflops per second through accelerators. The main memory totals 563 terabytes, the storage system for data around 6 petabytes.
The Lichtenberg supercomputer, which is operated by the University Computing Center (HRZ) of TU Darmstadt, is one of the fastest university computers in Germany and is represented twice in the current ranking of the Top500 supercomputers worldwide. With its first expansion stage, it is ranked 216th, and with its new (second) expansion stage, it is the winner among the participating Sapphire Rapid systems (4th generation Intel Xeon Scalable processors) and is thus ranked 230th on the list.
The investment costs for the Lichtenberg high-performance computer of 15 million euros are borne in equal parts by the federal government and the state of Hesse.
