Summary
ROQUO entered operation at RIKEN’s Kobe center after completing construction, giving the JHPC-quantum project a new GPU platform for quantum-HPC hybrid computing.
19.80 PFLOPS in FP64 on the HPL benchmark exceeded the system’s design target, using 135 NVIDIA GB200 NVL4 nodes with 540 Blackwell GPUs.
3.2-Tbps NVIDIA Quantum-X800 InfiniBand ties the nodes together and connects ROQUO via the SQC Interface to quantum computers and Japan’s flagship Fugaku supercomputer.
RIKEN said the warm-water-cooled system will serve researchers and industry while helping it build operating know-how for large GPU clusters and apply that experience to FugakuNEXT.
As Japan launches its advanced hybrid supercomputer, is the United States falling behind in the global quantum-HPC race?
How will Japan's new supercomputer prevent its mix of quantum systems from becoming too complex for researchers to use effectively?
When will the new ROQUO supercomputer deliver tangible breakthroughs in medicine and materials science beyond just benchmark speeds?
