Arm-Powered Fujitsu Supercomputer to fuel Aerospace Research at JAXA in Japan

Today Fujitsu announced that it has received an order for a supercomputer system from the Japan Aerospace Exploration Agency (JAXA). Powered by the Arm-based A64FX processor, 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. “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.”

Fujitsu Unveils Processor Details for Post-K Computer

The Fujitsu Journal has posted details on a recent Hot Chips presentation by Toshio Yoshida about the instruction set architecture (ISA) of the Post-K processor. “The Post-K processor employs the ARM ISA, developed by ARM Ltd., with enhancements for supercomputer use. Meanwhile, Fujitsu has been developing the microarchitecture of the processor. In Fujitsu’s presentation, we also explained that our development of mainframe processors and UNIX server SPARC processors will continue into the future. The reason that Fujitsu is able to continuously develop multiple processors is our shared microarchitecture approach to processor development.”
