Title: From Fugaku to Quantum HPC hybrid computing - The design of the supercomputer “Fugaku” and Challenges for beyond
Abstract: The supercomputer “Fugaku” is the first exascale system with 1 EFLOPS(SP) peak performance, which was operated since March 2021 in R-CCS, Japan. Fugaku is an ultra-scale “general-purpose” manycore-based system with 158,976 nodes, 7.6M cores in total. Fugaku was designed in application-oriented and power-efficient approach to accommodate variety kinds of large-scale applications. Recently, as several supercomputers such as ORNL Frontier and NNSA El Capitan in US are reaching to exascale, interests in the next of exascale Systems are increased. For the post exascale computing, many advanced HPC technologies are proposed such as aggressive integration of CPUs and GPUs, reconfigurable devices. On the other hand, new computing paradigm such as Quantum computing is gaining attention. We are conducting JHPC Quantum project to design and build a quantum-supercomputer hybrid computing platform by integrating different kinds of on-premises quantum computers, IBM superconducting quantum computer and Quantinuum trapped-ion quantum computer, with several supercomputers including Fugaku. In this talk, the experience of the development of Fugaku system will be presented followed by our JPC Quantum project.
