Fujitsu has recently announced that it has received an order for a supercomputer system from the Japan Aerospace Exploration Agency (JAXA), as the organization plans to expand its use in the HPC field in addition to conventional numerical simulations.
Scheduled to start operation in October 2020, the new computing system for large-scale numerical simulation, composed of Fujitsu Supercomputer PRIMEHPC FX1000, is expected to have a theoretical computational performance of 19.4 petaflops, which is approximately 5.5 times that of the current system. At the same time, Fujitsu will implement 465 nodes of x86 servers Fujitsu Server PRIMERGY series for general-purpose systems that can handle diverse computing needs.
The system will contribute in improving the international competitiveness of aerospace research, as it will be widely used as the basis for JAXA’s high-performance computing (HPC). It is also expected to be used for various applications, including a large-scale data analysis platform for satellite observation and an AI calculation processing platform for joint research.
As it conducts research of space development, aviation technology, and related basic technology, JAXA has used supercomputer systems to develop numerical simulation technologies such as fluid dynamics and structural dynamics in the study of aircraft and rockets. In recent years, in addition to conventional numerical simulations, the system has been expanding their role in the HPC field. For example, the system has processed earth observation data collected by satellites for use by researchers and the general public, while it has been used in AI calculations, including deep learning. JAXA is currently operating a supercomputer system JSS2 comprised of SORA-MA, which consists 3,240 nodes of Fujitsu Supercomputer PRIMEHPC FX100, and J-SPACE that stores and manages various data using a large-capacity storage medium.
Features of the New Supercomputer System
As a successor to the JSS2 system, Fujitsu will implement a computing system for large-scale numerical simulations. The system will consist 5,760 nodes of PRIMEHPC FX1000, which utilizes the technology of supercomputer Fugaku jointly developed by Fujitsu and RIKEN. It is expected to have 19.4 petaflops, approximately 5.5 times the theoretical computing performance of the current system, in double precision (64 bit) usually used in simulations. In addition, a total of 465 nodes from x86 servers Fujitsu Server PRIMERGY series equipped with high memory capacity and GPU will be deployed as they compose a general-purpose system capable of handling a variety of computing needs.
