HPC systems
Each of the HPC facilities consists of a compute resource (a number of compute nodes each with a number of processors and internal shared-memory, plus an interconnect that connects the nodes), a central storage resource that is accessible by all the nodes, and a secondary storage resource for back-up (and in few cases also for archiving). All facilities use variants of the UNIX operating system (Linux, AIX, etc.).
Storage systems
The NIRD storage provides data storage capacity for research projects with a data centric architecture. Hence it is also used for storage capacity for the HPC systems, for the national data archive and other services requiring a storage backend. It consists of two geographically separated storage systems. The leading storage technology combined with the powerful network backbone underneath allow the two systems to be geo‐replicated in an asynchronous fashion, thus ensuring high availability and security of the data.
The NIRD storage facility, differently from its predecessor NorStore, is strongly integrated with the HPC‐ systems, thus facilitating the computation on large datasets. Furthermore, the NIRD storage offers high performance storage for post processing, visualization, GPU‐computing and other services on the NIRD Service Platform

Betzy
The supercomputer is named after Mary Ann Elizabeth (Betzy) Stephansen, the first Norwegian woman with a Ph.D in mathematics.
The most powerful supercomputer in Norway
Betzy is a BullSequana XH2000, provided by Atos, and will give Norwegian researchers more than 5 times more capacity than previously, with a theoretical peak performance of 6.2 PetaFlops. The supercomputer, which will be placed at NTNU in Trondheim, will be available to users during the second half of 2020.
Technical specifications:
- The system comprises of 1344 compute nodes each equipped with 2 x 64core, next-generation AMD EPYC™ processors, code name ‘Rome’, for a total of 172032 cores installed on a total footprint of only 14.78m2. The total compute power will be close to 6Pflops.
- The system will consume 952kW of power and 95% of the heat will be captured to water.
- The computes nodes will be interconnected with the new generation of Mellanox HDR technology.
- The data management solution will rely on a DDN storage with a Lustre parallel file system of more than 2.5PB.

Fram
Named after the Norwegian arctic expedition ship Fram, the new Linux cluster hosted at UiT is a shared resource for research computing capable of 1.1 PFLOP/s theoretical peak performance. It started production 1 November 2017 (2017.2 computing period).
Fram is a distributed memory system which consists of 1004 dual socket and 2 quad socket nodes, interconnected with a high-bandwidth low-latency Infiniband network. The interconnect network is organized in an island topology, with 9216 cores in each island. Each standard compute node has two 16-core Intel Broadwell chips (2.1 GHz) and 64 GiB memory. In addition, 8 larger memory nodes with 512 GiB RAM and 2 huge memory quad socket nodes with 6 TiB of memory is provided. The total number of compute cores is 32256.

Vilje
Vilje is a cluster system procured by NTNU, in cooperation with the Norwegian Meteorological Institute and UNINETT Sigma in 2012. Vilje is used for numerical weather prediction in operational forecasting by met.no, as well as for research in a broad range of topics at NTNU and other Norwegian universities, colleges and research institutes. The name Vilje is taken from Norse Mythology.
Vilje is a distributed memory system that consists of 1440 nodes interconnected with a high-bandwidth low-latency switch network (FDR Infiniband). Each node has two 8-core Intel Sandy Bridge (2.6 Ghz) and 32 GB memory. The total number of cores is 23040.
The system is well-suited (and intended) for large scale parallel MPI applications. Access to Vilje is in principle only allowed for projects that have parallel applications that use a relatively large number of processors (≥ 128).
