Our research interest is mainly massively parallel systems. Researches of massively parallel systems have many processing levels; configuration of parallel arithmetic units in a VLSI chip, massively parallel systems that consist of a large number of microprocessors, PC-cluster that combines many Linux-PCs with high speed networks, and widely distributed systems such as GRID. We are developing construction method for or technology to use massively parallel systems. Followings are major research topics.chip level parallelization (FPGAs, Logical circuits, architectures)massively parallel computer architectures (interconnections, implementation methods, Wafer Scale Integrations, 3D Stack implementations, heat radiation.)GRID (GRID architecture, high speed networks for GRID)Japanese e-LearningProjects
