Introduction

Introduction​

Jötunn is one of three partitions available on the Elja cluster. The main purpose of Jötunn is to provide courses at the University of Iceland, that are teaching High performance computing, four compute-nodes that the partition consists of. These compute-nodes are shared between the partitions Jotunn and Elja so other users that are on the parititon Elja can also have access to these compute-nodes. However due to the short time-limit on the specified compute-nodes the flow of the queue should go fast. Therefore these four compute-nodes are not meant for calculations that would take more then one day to produce a result.

To know more about the Elja Cluster, which the Jotunn cluster is a part of, you can read more about it in the other chapters.

Here are recommended chapters to help you get started on using Jotunn
