Yasushi Negishi

Biography

Yasushi Negishi is a Research Staff Member at IBM Research - Tokyo. He belongs to the Deep Computing & Analytics group in Systems & Software. He joined IBM Research - Tokyo in 1989 after obtaining his M.S. degree in information science from the Tokyo Institute of Technology. He has more than 25 years of research experience. In 1989-1990, he researched system software, such as two-level threading systems, on the world’s second earliest symmetric multiprocessing machine called TOP-1. In 1990-1996, he improved the performance of the NFS server by about 15% by avoiding target data copy with functions of Ethernet adapters. In 1995-1996, he developed a communication protocol and system for video-on-demand software based on UDP/IP that achieved several times better communication stability than TCP/IP. In 1995-1999, he developed a communication protocol and system for PDAs (personal digital assistants) based on a synchronization mechanism. His protocol and system were used for a product providing the Lotus Notes database on PDAs. In 2000-2004, he worked on the design and development of a high performance processor for gaming, named CELL, in collaboration with Sony and Toshiba technicians. From 2008, he optimized HPC applications, such as FFT and CFD, on Blue Gene and other POWER processor machines. He also developed programming tools for optimization. Much of his work has been presented at major refereed conferences and in journals including INFOCOM, SC, Euro-Par, IPDPS, and TPDS. He is an ACM Senior member, and a member of IEEE and IPSJ. He has obtained more than fifteen patents in relation to his work.Yasushi Negishi is a Research Staff Member at IBM Research - Tokyo.
