NEC is set to supply Japan’s National Institutes for Quantum Science and Technology and National Institute for Fusion Science with a new supercomputer.

The system is scheduled to go live in July 2025 and will be used for various research and development in the field of fusion science research.

The unnamed supercomputer will be housed at the Rokkasho Institute for Fusion Energy, QST, in the Aomori Prefecture of Japan.

Consisting of 360 NEC LX 204Bin-3s, with a total of 720 Intel Xeon 6900Ps, 70 NEC LX 401Bax-3GAs, and 280 AMD Instinct MI300As, the system will be equipped with MRDIMM (Multi-Capacity Rank Dual In-Line Memory Modules) and have a theoretical performance of 40.4 petaflops of computing power. This is approximately 2.7 times higher than the combined performance of the two supercomputers currently installed at QST and NIFS.

In a statement, NEC said the system consists mainly of the LX series which combines the high-density packaging technology and high-efficiency cooling technology and has been developed by the company over a number of years.

The supercomputer will also comprise Nvidia InfiniBand networking and a QM9700 switch and have 42.2 petabytes of DataDirect Networks ES400NVX2 ExaScaler storage offering.

NEC added that the deployment of the Intel CPU Xeon 6900P, MRDIMM, and AMD’s Instinct MI300A GPUs is the first introduction of its kind in Japan.

“Intel is proud to partner with NEC to power a system at the National Institutes for Quantum Science and Technology and National Institute for Fusion Science,” said Ogi Brkic, VP & GM, go-to-market builders & technology acceleration office, sales & marketing group, Intel. “By integrating the Intel Xeon 6900P Series, the first server CPU to support MRDIMMs, and the first in Japan, we’re delivering a leap in memory performance and bandwidth, an ideal choice for complex calculations and simulations required in fusion research.”
