NEC announced yesterday that it has received an order for a next-generation supercomputer system from the Japan Agency for Quantum Science and Technology (QST) and the National Institute for Fusion Science (NIFS). The new supercomputer will be installed at QST's Fusion Energy Laboratory in Kamikita County, Aomori Prefecture, and is scheduled to be put into operation in July 2025.
▲ Installation location
NEC is responsible for building this supercomputer, which includes 360 LX 204Bin-3 units and 70 LX 401Bax-3GA units, combining hardware products from Intel, AMD, and Nvidia:
▲ Left side LX 204Bin-3 Right side LX 401Bax-3GA
The former unit is a dual-CPU node server equipped with two Intel Xeon 6900P "Granite Rapids-AP" processors and MRDIMM memory sticks; the latter unit each accommodates four AMD Instinct MI300A accelerators/data center APUs; in addition, the network part uses NVIDIA's 400Gb/s port speed InfiniBand switch Quantum-2 QM9700.
After completion, the supercomputer's theoretical performance can reach 40.4 petaflops (IT Home Note: Taking various factors into consideration, it is roughly equivalent to the top 30 of the TOP500 list), which is about 2.7 times the combined computing power of the existing supercomputers of QST and NIFS.
This supercomputer is expected to be used for various R&D activities in the field of nuclear fusion scientific research, including accurate predictions for experiments of the International Thermonuclear Experimental Reactor ITER and its predecessor, the superconducting tokamak prototype reactor JT-60SA, and participating in the design of the DEMO reactor aimed at achieving carbon neutrality.
