Following on from 2005 and 2009, the Bavarian centre of higher education once again commissioned the supercomputer specialist Megware with the order to deliver cutting-edge, high-performance technology. The high-performance computer btrzx3 consists of a total of 12 server racks. It integrates 416 nodes, each consisting of two AMD Opteron 6348 2.8 GHz processors, and four 4-way servers. The computer nodes have 64GB or 128GB of RAM and are connected via a fast QDR Infiniband network.
Supercomputers are of crucial importance in research. The new btrzx3 is mainly intended for highly parallel computing tasks. The computing tasks that demand a high single-core performance can draw on the predecessor system "btrzx5", which Megware also supplied. Scientists in Bayreuth are principally involved in the computation of tasks in the fields of physics, biochemistry and material sciences. The new resources are already in use at the moment to calculate the behaviour of plasma, as found on the sun's surface, in their dependence on magnetic fields. Roughly 8,000 of the over 10,000 processor cores are momentarily occupied with these calculations. The btrzx3 is in operation 24/7 in order to cater to the high demand for this kind of computing power.
The HPC cluster is housed in the newly erected laboratory and internship building in the University of Bayreuth, soon to play host to several faculties, including biochemistry, geosciences and mechatronics. The sheer size of the system and its continuous operation generate extremely high temperatures - and this waste heat is used to supply the entire building.
"Publication of the latest ranking of the world's highest-performance supercomputers clearly demonstrates that for the first time, four Megware systems are found in the TOP500 list and the Chemnitz-based company is clearly the number 1 among German supercomputing manufacturers", stated Jana Mitschke, Marketing Manager at Megware. In addition to Bayreuth, further Megware TOP500 clusters are located at the universities in Oslo, Mainz and Vienna.
