The supercomputer "Oakforest-PACS" operated by the state-of-the-art joint HPC infrastructure facility (JCAHPC) reached 2016th place in the TOP11 list showing the world supercomputer performance ranking in November 500, and "K computer" computer (6th place). ) Was registered as the highest performance system in Japan.The computer was manufactured by Fujitsu Limited and installed in JCA HPC, which is jointly operated by the Information Technology Center of the University of Tokyo and the Center for Computational Sciences of the University of Tsukuba, and the system has been in operation since October.
Oakforest-PACS will be set up at the Information Infrastructure Center on the Kashiwa Campus of the University of Tokyo, but the two universities, the University of Tokyo and the University of Tsukuba, will jointly carry out all of the system procurement, introduction, operation, and operation of the main usage programs. The first attempt in Japan.The system is a massively parallel cluster type supercomputer that connects 2 computing nodes using Intel's high-performance processor Intel Xeon Phi (Knights Landing architecture) using manycore processor technology, also using Intel's Omni-Path architecture.Due to advances in semiconductor technology and interconnect network construction technology over the last five years, the highest performance in Japan has been achieved for systems using commercially available processors.
The results of the LINPACK benchmark test, which measures the performance of computers, achieved 13.55 petaFLOPS (1K 3550 trillion floating-point arithmetic speeds per second [1 peta is 1 million times 100 giga]).The peak performance of the system is 25 petaFLOPS, which is about 2.2 times that of the "K computer".
Oakforest-PACS will be shared as a supercomputer resource with the highest performance in Japan, and will dramatically promote research and development in various next-generation science and technology fields.In addition to research on cutting-edge computational science, it is also used for human resource development in the fields of computational science and HPC (high performance computing), and is expected to contribute to the future development of each field.
