Arrhenius CPU contains two CPU node types, 192 thin nodes, and 20 fat nodes. Each node have 256 cores split between two CPU:s. The thin nodes have 768 GB RAM and the fat nodes have 3072 GB RAM. There is a 1.92 TB local SSD on each node. It is accompanied with the Arrhenius Disk and Arrhenius Flash storage systems.
Arrhenius CPU is primarily intended for work that cannot be moved to the much more powerful accelerated computational resource, the Arrhenius GPU. Projects with such needs will be prioritized on Arrhenius CPU.
