Dongarra Report Confirms Details on 54 Petaflop Chinese Supercomputer

Jack Dongarra from the University of Tennessee has posted a detailed report on the new 54 Petaflop Tianhe-2 supercomputer in China. In what will most certainly land the system at #1 on the upcoming TOP500 list, the hybrid system scored a remarkable 30.65 Petaflops on LINPACK.

As first-reported by a Chinese paper called M.I.C Gadget back in December, the hybrid system is powered by Intel Xeon and Intel Xeon Phi coprocessors. And while conflicting details of the machine began to appear last week on Twitter, Dongarra’s report is based on a May 28 briefing in Changsha by a Chinese official from the National University of Defense Technology (NUDT).

The TH-2 was developed by NUDT and Inspur. Inspur is a Chinese multinational information technology company headquartered in Jinan, Shandong, China. Inspur’s business activities include server manufacturing and software development. Inspur contributed to the manufacturing of the printed circuit boards and is also contributing to the system installation and testing. The TH-2 is undergoing assembly and testing at NUDT and will be moved to its permanent home at the National Supercomputer Center in Guangzhou (NSCC-GZ) by the end of the year. The complete system has a theoretical peak performance of 54.9 Pflop/s. It is based on Intel’s Ivy Bridge and Xeon Phi components and a custom interconnect network. There are 32,000 Intel Ivy Bridge Xeon sockets and 48,000 Xeon Phi boards for a total of 3,120,000 cores. This represents the world’s largest (public) installation of Intel Ivy Bridge and Xeon Phi’s processors. The system will be located in Southwest China.
