The well-known Japanese company Fujitsu has completed the development of a new technology called PRIMEHPC, on the basis of which the Fugaku exaflops supercomputer will be built in 2021. With this, Japan plans to regain the title of the country that created the fastest supercomputer in the world, replacing the K supercomputer, which is now at the disposal of the Riken State Research Institute, with this computer. The Fugaku supercomputer will be approximately 40 to 120 times faster than the K supercomputer, and its performance will reach more than 10 quadrillion floating point calculations per second.
PRIMEHPC technology supports the time-tested Tofu D interconnect, which will enable the Fugaku system to scale and provide a density of up to 384 compute nodes per standard rack. Due to this, it will be possible to create efficient computing systems of any scale based on the FX1000 racks, the maximum theoretical performance of which is 1.3 exaflops. The currently available rack models FX1000 and FX700 use a water cooling system, which helps increase efficiency and reduce energy consumption.
Some time ago, the United States and China announced plans to build supercomputers with comparable performance to Fugaku by 2020 and 2021. The first American exaflop level system will be the Aurora supercomputer, which in 2021 should receive at its disposal the Argonne National Laboratory of the US Department of Energy.
However, there is, albeit very small, but the likelihood that the implementation of the plans of the United States and China to create exaflops-level supercomputers will run into problems and will be extended at a later date. And in this case, Japan has every chance of becoming the first country to build an exaflops-level supercomputer.
Meanwhile, Fujitsu plans to start global sales of the PRIMEHPC FX1000 and PRIMEHPC FX700 racks, which will be the first representatives of the Fujitsu Supercomputer PRIMEHPC series. And the first deliveries of supercomputer equipment built on the basis of the most modern technologies will be launched as early as March 2020.
