Abisko is the newest HPC cluster at HPC2N. It is comprised of 322 nodes with a total of 15456 CPU cores of which 318 nodes are available to our users. Each node is equipped with 4 AMD Opteron 6238 (Interlagos) 12 core 2.6 GHz processors.
“The latest AMD technology with several energy-efficient processor cores and large memory capacity per node makes the system unique and provides the researchers with a great flexibility to accomplish many different computations and simulations.”
Professor Bo Kågström, HPC2N Director
Each 'fat' node has 1 TB local storage. Each 'thin' node has 500GB local storage.
Abisko has a theoretical peak performance of 160.74 TF and is reaching 131.9 TF with the HP LINPACK benchmark (82.05% efficiency).
Abisko runs Ubuntu Linux. It has PathScale, Intel, Portland Group, and GNU compiler suites installed, as well as MPI libraries.
"HPC2N is of course more attractive to our users and also our own research in parallel algorithm and software design gets more impact when we develop in pace with the technology evolution. For all researchers, it gives the possibility to study even more complex and large-scale computational problems in various fields."
Professor Bo Kågström
