Taisuke Boku

Professor and Deputy Director, Center for Computational Sciences, University of Tsukuba

Taisuke Boku received Master and PhD degrees from Department of Electrical Engineering at Keio University. After his carrier as assistant professor in Department of Physics at Keio University, he joined to Center for Computational Sciences (former Center for Computational Physics) at University of Tsukuba where he is currently the deputy director, the HPC division leader and the system manager of supercomputing resources.He has been working there more than 20 years for HPC system architecture, system software, and performance evaluation on various scientific applications. In these years, he has been playing the central role of system development on CP-PACS (ranked as number one in TOP500 in 1996), FIRST (hybrid cluster with gravity accelerator), PACS-CS (bandwidth-aware cluster) and HA-PACS (high-density GPU cluster) as the representative supercomputers in Japan. Also, He is a member of system architecuture working group of Post-K Computer development. He is a coauthor of ACM Gordon Bell Prize in 2011.

Talk Title:

AiS: New Paradigm of Parallel FPGA Computing

Talk Abstract:

In this talk, I will present our current research on advanced hybridcluster computing with the latest FPGA technology to provide flexibleand power-effective accelerated computing in next generation. We apply FPGA technology not just for computation but also for interconnection for large scale parallel systems without communication bottleneck. The concept is based on the high performance optical interconnection interface suited in the latest version of FPGA with up to 100Gbps speed on multiple communication ports. Using Ethernet prootocol on it, we can easily build a large scale low latency communication network in a new method of parallel FPGA system construction. We have been developing a prototype system of such a concept named AiS (Accelerator in Switch) to gather the computation and communication on FPGA device with flexible programming based on OpenCL instead of traditional Verilog HDL, for user friendly FPGA programming. In this talk, the brief image and prototype design/implementation of AiS-based system developed in Center for Computational Sciences, University of Tsukuba is presented as well as our latest research on Japan's fastest supercomputer Oakforest-PACS under collaboration between University of Tsukuba and the University of Tokyo.
