Mitsuhisa  Sato(Ph.D.)

The architecture development team designs the architecture of the post "K" supercomputer in cooperation with our partner vendor. As well as an evaluation environment for the design of the new architecture, we develop a parallel programming language called XcalableMP (XMP) for the post "K".
