The supercomputer is named after the godess in norse mythology associated with wisdom. Saga is also a term for the Icelandic epic prose literature. The supercomputer, placed at NTNU in Trondheim is designed to run both sequential and parallel workloads. It was made available to users right before the start of the 2019.2 period (October 2019).

Saga is provided by Hewlett Packard Enterprise and has a computational capacity of approximately 85 million CPU hours a year and a life expectancy of four year, until 2023.

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.
