Contract signed for new Arrhenius national supercomputer in Sweden

The contract for the new Swedish supercomputer system Arrhenius has been signed! The EuroHPC Joint Undertaking (EuroHPC JU) and the National Academic Infrastructure for Supercomputing in Sweden (NAISS) have financed 35% and 65% of the system, respectively. The system will be hosted in Linköping, Sweden, and will be supplied by Hewlett Packard Enterprise (HPE). Some excellent news for Swedish and European researchers is that the system will be considerably faster and more capable than NAISS initially thought possible, which will significantly benefit the researchers who will use the system.

The system will have several partitions for different kinds of research computation. The configuration of the high-performance computing (HPC) partition includes 424 AMD Turin 128-core CPUs and 382 GPU nodes, each with four NVIDIA GH200 Grace Hopper Superchips. The GPU part is expected to have an HPL (High-Performance Linpack) performance of more than 60 PFLOPS. There will also be one partition for cloud computing and another partition dedicated to sensitive data. Storage will be provided by a 29 PB fast parallel file system. The system will be installed in stages starting in the autumn of 2025 and will be completed in the spring of 2026.

“Gert Svensson [NAISS Deputy Technical Director and Arrhenius project manager] and the teams from NAISS and EuroHPC have done a fantastic job. This marks a milestone for Sweden as it is our first new national HPC system, and the first time that we will be hosting a node in the international EuroHPC infrastructure. But, above all, it is an investment in groundbreaking research across all fields of science,” says NAISS Director, Erik Lindahl.
