Fujitsu supercomputer PRIMEHPC FX1000 and FX700 were announced last year and they have been kept strong attentions from researchers, application developers, and research institutes due to their high performance, low power consumption and usability. The biggest reason for this is the full compatibility with the supercomputer Fugaku, which is developed by RIKEN and Fujitsu and the first supercomputer in the history receiving the first prizes in three major supercomputers’ ranking, TOP500, HPCG, and Graph500 at the same time in June 2020. In addition to that it also received the first prize in the HPL-AI ranking. FX1000 is the same hardware with the Fugaku and capable to support the same software stack except LLIO, Light weight Layered IO accelerator designed for the large and scalable environment like Fugaku system. FX700 uses A64FX CPU developed by Fujitsu and used for Fugaku, and supports the same operating system, Red Hat Enterprise Linux 8, while supporting the de facto standard interconnect, InfiniBand HDR. Fujitsu supercomputers and its derivatives form a center of excellence of Arm HPC ecosystem. Since the Fujitsu system software, known as TCS (Technical Computing Suite), also supports x86 cluster, the supercomputer system having Arm and x86 can be used as single system image operation. In this presentation, our recent efforts and achievements will be presented and discussed.
