Title: An Overview of RIKEN’s System Software Research and Development Targeting the Next Generation Japanese Flagship Supercomputer

Abstract:
RIKEN Advanced Institute for Computation Science has been appointed by the Japanese government as the main organization for leading the development of Japan’s next generation flagship supercomputer, the successor of the K. Part of this effort is to design and develop a system software stack that suits the needs of future extreme scale computing. In this talk, we first provide a high-level overview of RIKEN’s system software stack effort covering various topics, including operating systems, I/O and networking. We then narrow the focus on OS research and describe IHK/McKernel, our hybrid operating system framework. IHK/McKernel runs Linux with a light-weight kernel side-by-side on compute nodes with the primary motivation of providing scalable, consistent performance for large scale HPC simulations, but at the same time, to retain a fully Linux compatible execution environment.  We detail the organization of the stack and provide preliminary performance results.
