FUJITSU Supercomputer PRIMEHPC

Petascale Supercomputer


High-performance, highly scalable, highly reliable, superior power-saving supercomputer

The PRIMEHPC series is equipped the same A64FX CPU as in the supercomputer Fugaku developed together with Japan’s leading research institute, RIKEN. It achieves extremely high performance for the amount of power it consumes, and features high scalability.

With these models it is possible to achieve a safe, secure society through things like accelerating the development of new medicines, reducing and preventing natural disasters, developing new materials, manufacturing without the need for prototyping, resolving societal issues, progressing cutting-edge research, and boosting business competitiveness.

PRIMEHPC FX1000



High-performance, highly scalable yet very reliable supercomputer for extremely large-scale systems



Thanks to its use of the same technology as the supercomputer Fugaku, this model is capable of providing theoretical peak performance of more than 1.3 Exaflops. Not only does it provide high-performance, high scalability and high reliability, it also realizes the world's greatest levels of ultra-low power consumption. It will open new horizons for research and development involving supercomputers.


PRIMEHPC FX700



An easily deployed model in the PRIMEHPC series based on standard technology and using the same A64FX CPU as the supercomputer Fugaku



A high-performance Arm server featuring the same A64FX CPU as the supercomputer Fugaku. It can be mounted in conventional 19-inch racks and is air-cooled, making it easy to deploy.
