Fram¶

Named after the Norwegian arctic expedition ship Fram, the new Linux cluster hosted at UiT Arctic University of Norway is a shared resource for research computing capable of 1.1 PFLOP/s theoretical peak performance.

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.

No network access on compute nodes¶

According to our security policy, compute nodes shall not have direct access to the public internet. This means that commands like git clone or conda install or pip install, updating Git submodules, fetching data from web sources, etc., will not work on compute nodes.
