What simply occurred? In the course of the ActivateNow: Expertise Summit held on the Laptop Historical past Museum in California final week, a Fujitsu consultant off-offhandedly talked about an upcoming Arm-based CPU slated for 2027 that caught the eye of some within the viewers. The Register pressed the corporate for extra particulars and discovered it was creating a successor to the A64FX codenamed Monaka.
Fujitsu launched its first Arm-based high-performance compute (HPC) CPU in 2019. The bluntly-named A64FX has 48 processor cores clocked round 2GHz and 4 extra assistant cores. It has 32 GB of onboard HBM2 and plenty of extra HPC options together with 512-bit scalable vector extensions (SVEs). Nearly 160,000 A64FXs energy the Fugaku supercomputer, which was the quickest supercomputer on the planet from 2020 to 2022 when it was succeeded by the Epyc-powered Frontier.
Monaka “may have a wider vary of options and can show extra vitality environment friendly” than the A64FX, a spokesperson informed The Register. “The vary of potential purposes is wider than that of the A64FX, which has particular traits (eg, interconnects) particular to Fugaku.” A few of these traits embrace the Tofu interconnect D cloth and the restrict of 32 GB of reminiscence, which might’t be expanded.
Power effectivity is a precedence within the design of Monaka. Fujitsu emphasizes its “overwhelming vitality effectivity” that may “contribute to the belief of a carbon-neutral and sustainable society” in its supplies. The corporate hopes that the CPU will likely be no less than 70 p.c quicker than its opponents in AI and HPC workloads whereas being twice as environment friendly.
Japan’s New Power and Industrial Expertise Improvement Organisation (NEDO) is encouraging and supporting Fujitsu in its endeavors to create extra energy-efficient processors as a part of its plan to scale back the vitality consumption of knowledge facilities in Japan by 40 p.c by 2030. As a part of the initiative, Fujitsu can also be contributing to the co-development of different energy-efficient applied sciences, together with low-power accelerators and photonics-based community interface controllers (NICs).
Arm-based processors are proving to be a preferred choose in nations that incentivize sustainability. Arm processors are intrinsically extra environment friendly than x86 options, with Amazon, Google, and Nvidia all investing of their utility to HPC workloads proper now.
