The continuous improvement in processing speed in high-performance computer systems such as the supercomputers K and Fugaku have been enabled by transistor scaling. This trend is known as Moore’s law. But Moore’s law is predicted to end in the near future. Hence, it is vital to research and develop novel and more efficient high performance computer systems if we are to continue realizing high performance computing in the future.
Based on the experience of hardware development and the existing software environment of the supercomputers K and Fugaku, we are researching and developing a next-generation high-performance computer architecture together with strategies to improve the power efficiency of exascale supercomputer systems. Currently, we are mainly focusing on non-von Neumann architectures such as systolic arrays and neuromorphic computers based on the latest advances in device technologies, architectures that can integrate next generation non-volatile memories and/or various types of accelerators into a general-purpose processor, the advancement of scientific simulations by accelerating machine learning computations, and hybrid computing architectures that combine the benefits of quantum computing and classical computing. And we are performing detailed co-design (coordinated design of hardware and software) evaluations of the computer architectures noted above as well as the co-design evaluations of algorithms that take advantage of them on the supercomputers K and Fugaku.
