Next Generation High Performance Architecture Research Team
RIKEN Center for Computational Science
(Team Leader: Masaaki Kondo)

Research Field

The RIKEN Center for Computational Science (R-CCS), led by Center Director Satoshi Matsuoka, is an international hub for computational science that promotes “science of computing, by computing, and for computing.” R-CSS positions the technology in which RIKEN has strengths (R-CCS technology) and the software developed by RIKEN that contributes to science, technology, industry, and society (R-CCS software) as its “core competence in computational science driving science as a whole.” R-CCS aims to develop these technologies, disseminate them domestically and internationally, and produce results. In addition, R-CCS is utilizing its expertise to operate the supercomputer “Fugaku” which was developed as a national project in accordance with Japanese laws and regulations.

For the purposes of enhancing utilization of the Fugaku supercomputer as well as advancing future high performance computing infrastructures, the Next Generation High Performance Architecture Research Team is intended to tackle the following research agendas:

• Ultra high-bandwidth architecture based on novel technologies such as next generation non-volatile memory, 3D stacked memory, as well as advanced optical interconnect
• Re-evaluation of non von Neumann architectures such as dataflow and systolic arrays based on latest advances in device technologies
• Next generation ultra power-efficient architectures based on the integration of various types of accelerators and general purpose processors
• HPC-quantum hybrid computing system and its software environment to exploit the benefits of both quantum computing and classical computing
• Detailed co-design evaluation and benchmarking of high-performance computer systems and next generation architectures above for taking advantage of them on the Fugaku
