HPC2N currently operate two clusters, Abisko (AMD Interlagos cluster comprised of 318 nodes with a total of 15264 cores and 44.5 TB RAM), and Akka (Intel Xeon cluster comprised of 672 nodes with a total of 5376 cores and 10.7 TB RAM).

Abisko began installation during the fall of 2011, and a partial - or interim system - was in use until february 2012, when the final system was installed.

Abisko has a theoretical peak performance of 158.75 TF, while Akka has a theoretical peak performance of 53.8 Teraflops.

Aside from those two clusters, HPC2N also has Ritsem (Intel Xeon cluster with 68 nodes and  total of 584 cores and 584 GB RAM), which is used to run grid jobs on Swegrid. We also provide tape storage through Bender - an IBM TS3500 tape library with IBM Ultrium4 tape drives.
