QPACE 2 (QCD Parallel Computing Engine) is a massively parallel and scalable supercomputer. It was designed for applications in lattice quantum chromodynamics but is also suitable for a wider range of applications.. == Overview == QPACE 2 is a follow-up to the QPACE supercomputer〔 and the iDataCool hot-water cooling project.〔 It is a combined effort of the particle physics group at the University of Regensburg and the Italian company Eurotech. The academic design team consisted of about 10 junior and senior physicists. Details of the project are described in.〔 QPACE 2 uses Intel Xeon Phi processors (a.k.a. KNC), interconnected by a combination of PCI Express (abbreviated PCIe) and FDR InfiniBand. The main features of the QPACE 2 prototype installed at the University of Regensburg are * scalability * high packaging density * warm-water cooling (no chillers are needed) * high energy efficiency * cost-effective design The prototype is a one-rack installation that consists of 64 nodes with 15,872 physical cores in total and a peak performance of 310 TFlop/s. It was deployed in the summer of 2015〔 and is being used for simulations of lattice quantum chromodynamics. In June 2015, QPACE 2 was ranked #379 on the Top500 list of the most powerful supercomputers〔 and #26 on the Green 500 list of the most energy-efficient supercomputers of the world.〔 QPACE 2 was funded by the German Research Foundation (DFG) in the framework of SFB/TRR-55 and by Eurotech. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「QPACE2」の詳細全文を読む スポンサード リンク
