Fujitsu announced it will launch a cloud service based on the same hardware used n the world's fastest supercomputer, Fugakui.

The first step in what it calls Fujitsu Computing-as-a-Service (CaaS) will be Fujitsu Cloud Service HPC, which offers the high-performance computing power of the Fujitsu Supercomputer PRIMEHPC FX1000, which is based on the A64FX 64-bit Arm processor Fujitsu developed specifically for Fugaku.

The A64FX is a 48-core custom Arm processor designed for HPC that does not use traditional DRAM memory sticks, or DIMMs. Instead it has 32GB of high bandwidth memory (HBM) directly on the CPU die sitting right next to the CPU chip itself.

So in addition to performance, Fugaku is extremely power efficient because it doesn't have any memory DIMMs sucking up power. Fugaku debuted at the number one position on the TOP500 list of supercomputers in June 2020 and has remained there. It also debuted at the top of the Green 500 list of the most power-efficient supercomputers, although It has since fallen out of the top spot.
