New supercomputer named Saga

Uninett Sigma2 invited our users to participate in the naming of the new supercomputer, previously known as C1. We received more than 400 different suggestions, and eventually Saga was named the winner.

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, which will be placed at NTNU in Trondheim, is designed to run workloads from Abel and Stallo. It will be available to users during the second half of 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 yearuntil 2023.
