Video: System Software in Post K Supercomputer

SC15-2In this video from SC15, Yutaka Ishikawa from RIKEN AICS presents: System Software in Post K Supercomputer.

“The next flagship supercomputer in Japan, replacement of K supercomputer, is being designed toward general operation in 2020. Compute nodes, based on a manycore architecture, connected by a 6-D mesh/torus network is considered. A three level hierarchical storage system is taken into account. A heterogeneous operating system, Linux and a light-weight kernel, is designed to build suitable environments for applications. It can not be possible without codesign of applications that the system software is designed to make maximum utilization of compute and storage resources. After a brief introduction of the post K supercomputer architecture, the design issues of the system software will be presented. Two big-data applications, genome processing and meteorological and global environmental predictions will be sketched out as target applications in the system software design. Then, it will be presented how these applications’ demands affect the system software.”

Yutaka Ishikawa is in charge of developing Post K computer, and he is also involved with the design of the post T2K open supercomputer based on manycore architecture at universities of Tsukuba and Tokyo. Ishikawa received the BS, MS, and PhD degrees in electrical engineering from Keio University. From 1987 to 2001, he was a member of AIST (former Electrotechnical Laboratory), METI. From 1993 to 2001, he was the chief of Parallel and Distributed System Software Laboratory at Real World Computing Partnership. He led development of cluster system software called SCore, which was used in several large PC cluster systems around 2004. From 2002 to 2014, he was a professor at the University Tokyo. He led the project to design a commodity-based supercomputer called T2K open supercomputer. As a result, three universities, Tsukuba, Tokyo, and Kyoto, obtained each supercomputer based on the specification.

SC16 takes place November 13-18 in Salt Lake City.
