SC15 Invited Talk Spotlight: Dr. Yutaka Ishikawa Presents System Software in Post K Supercomputer

The K computer manufactured by Fujitsu, currently installed at the RIKEN Advanced Institute for Computational Science campus in Kobe, Japan.

The next flagship supercomputer in Japan, replacement of K supercomputer, is being designed toward general operation in 2020. Compute nodes, based on a many core architecture, connected by a 6-D mesh/torus network is considered. A three level hierarchical storage system is taken into account.

Co-kernel approach for HPC OS: Separation of system and process activities.

A heterogeneous operating system, Linux and a light-weight kernel, is designed to build suitable environments for applications. It cannot be possible without co-design 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 in this Talk. 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.

Dr. Yutaka Ishikawa
Speaker Background:    
Dr. Yutaka Ishikawa is the project leader of post K supercomputer development. 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 in 2008. He has been involved in the design of the post T2K machine since 2013, which will be operational in 2020.
