The Idun cluster is a project between NTNU's faculties and the IT division that aims at providing a high-availability and professionally administrated compute platform for NTNU. It is an effort to combine the compute resources of individual shareholders to create a cluster for rapid testing and prototyping of HPC software. While the IT division provides the backbone of the cluster, such as switches for high-speed interconnection, storage, and provisioning servers, the individual faculties/departments provide the compute resources. Any faculty or department can become a shareholder in the cluster by financing compute capacity, leveraging their share of compute time as well as the compute time of other idling resources. Accounting guarantees each partner's share of compute time and ensures fairness between the users on the system. More:
