@HPCpodcast: Satoshi Matsuoka on the TOP500, Fugaku and Arm, Quantum and Winning Japan’s Purple Ribbon Medal of Honor

Satoshi Matsuoka

An eminent figure in the HPC community, Prof. Satoshi Matsuoka, director of the RIKEN Center for Computational Science (R-CCS) and professor of computer science at Tokyo Institute of Technology, joined our @HPCpodcast for a far ranging discussion of supercomputing – past, present and future.

At RIKEN, Matsuoka has overseen development of Fugaku, number 1 on the TOP500 list of the world’s most powerful supercomputers (the list will be updated next week during the ISC 2022 conference in Hamburg — as of now it’s not known if Fugaku will retain its position). Previously, Matsuoka was lead developer of another well-know supercomputer, TSUBAMI, the most powerful supercomputer in Japan at the time.

He also is a recent winner of the Purple Ribbon Medal, one of Japan’s highest honors, and in our conversation Matsuoka explains why the award ceremony did not include the usual presence of the Emperor of Japan. That’s how our discussion starts; other topics are time stamped below:
