 | 【講演概要】Facing the end of Moore’s law, new approaches to improve processing performance and reduce power consumption at the same time have been required. One of the promising approaches is multicore computing that allows us to reduce power consumption using lower frequency processor cores and increase processing performance by integrating multiple cores on a chip including accelerator cores since the power is proportional to the cubes of frequency. Though multicore hardware allows us to increase performance in proportion to the number of processor cores theoretically, in reality, it is difficult to obtain the scalable performance without software collaboration because parallelization of the program, reduction of synchronization overhead, memory access optimization, and so on are essential to get the scalable performance improvement. Also, use of accelerators is effective for performance improvement and power reduction of a system. However, such multicore systems using accelerators sometimes need tuning to optimize memory access and improve the parallelism of target programs. The hand tuning often increases total software development time and cost. The multicore computing should be implemented with co-design of architecture and software looking at real applications to realize scalable performance improvement, reduction of power consumption, and minimization of software development period and cost. This talk introduces future of high-performance low power multicore computing considering software development cost and time that are important factors to use multicores in various applications including automobiles, IoT, deep learning, medical systems, cloud servers, big data, smart city, supercomputers and so on. 【略歴】Hironori Kasahara is an IEEE Computer Society President 2018 and a professor in the Department of Computer Science and Engineering at Waseda University.
