Arrhenius

Host data centre

NSC, Linköping University

Description

Arrhenius is the new powerful supercomputer that NAISS is building together with EuroHPC. It is scheduled to come online in early 2026.

The procurement process concluded in July 2025 with the selection of HPE to deliver the system with the following specifications:

• A HPC partition with 424 AMD Turin 128-core CPUs and 382 GPU nodes, each with four Grace Hopper Superchips from Nvidia
• One partition for cloud computing
• One partition dedicated to sensitive data
• A fast 29 PB parallel file system for storage.

The GPU part is expected to have an HPL (High-Performance Linpack) performance of more than 60 PFLOPS – approximately seven times that of the current most powerful NAISS system, Dardel.

The contract includes training and collaboration efforts to port and optimise scientific applications to Arrhenius. To ensure good service and maintenance, HPE will also place an on-site engineer at NAISS.

The system is named after Swedish geologist and chemist Carl Axel Arrhenius who discovered the mineral gadolinite.
