Bull delivers Finland’s national supercomputer Roihu to CSC’s Kajaani data center

High-performance computing company Bull has delivered Finland’s latest national supercomputer to the country’s IT Center for Science’s (CS) Kajaani data center.

Dubbed Roihu, the system will replace the center’s existing Mahti and Puhti machines, tripling the computing capacity of the center whilst also significantly increasing its AI performance.

Housed in the same data center as EuroHPC’s Lumi supercomputer, CSC said the Roihu will complement the existing system by “addressing national scale workloads and ensuring broad access for Finnish universities and research institutes.”

Based on Eviden’s BullSequana XH3000 hybrid platform, the supercomputer increases CSC’s GPU capacity by more than 10x, providing 49 petaflops of theoretical peak performance. Comprising 486 CPU nodes and 132 GPU nodes, each CPU node will have two 192-core AMD Turin 9965 CPUs, while the GPU nodes will be equipped with four Nvidia GH200 Grace Hopper superchips.
