Title
Bio
Profile
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 30 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. In 2008-2016, he optimized HPC applications, such as FFT and CFD, on Blue Gene and other POWER processor machines. He also developed programming tools for optimization. In 2017-2020, he worked for optimization of deep learning frameworks, such as TensorFlow. From 2020, He works for onnx-mlir project, which provides a compiler technology to transform a valid Open Neural Network Exchange (ONNX) graph into code that implements the graph with minimum runtime support. It implements the ONNX standard and is based on the underlying LLVM/MLIR compiler technology. 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, an IPSJ Seniar Member, and a member of IEEE. He has obtained more than forty patents in relation to his work.
