High Performance Computing

The High Performance Computing (HPC) service provides access to computing facilities and software with a far greater capacity than is normally available at department and faculty levels. This service is primarily set up to run simulation calculations for research and education purposes, designed as batch processing runs.

Access to computations and related services, including user support, is granted following individual applications. The work to be carried out must meet requirements for scientific quality. Large-scale calculations must also meet requirements for efficient execution. The researcher must comply with the acceptable use policy and the ICT policy at their respective research institutions. An annual report stating the results and achievements from the calculations must be prepared.

Description of the service: 

The high performance computing service is a support service for research and education in the university and university college sector. Staff in this sector will apply for resources to carry out calculations, primarily through processor time (CPU-hours) on selected sites. It is also possible to apply for advanced user support (AUS), for help to tailor or improve software. Applications for computing time or tailoring will be evaluated and granted by a resource allocation committee (RFK), appointed by the Uninett Sigma2 Board, normally twice a year. Calls for proposals are published on the Uninett Sigma2 website, normally in January and July. Extensions on previously allocated time and applications for small grants for testing are processed continually. When resources are allocated, the customer will administer a project with allocated resources, and it is up to the customer to decide which persons (users) will use the allocated time.

In addition to processor time and advanced technical support, this service gives the customer access to:

•    Basic technical support through a ticket-based support service

•    Training in programming, software optimization and other relevant topics

•    A basic software portfolio, primarily comprising open source code and certain commercial tools, such as compilers, debuggers, performance tools and simulation applications.


Research and education at universities and colleges are provided resources by application, provided the criteria for scientific quality are met. Resources are generally free of charge, but for certain categories, there is an associated cost. This applies to:

  • Large projects with funding of 15 MNOK or more, from the Norwegian Research Council
  • Non-commercial projects needing Dedicated Resources
  • Commercial research and industry projects

For information about the actual cost level, contact sigma2@uninett.no

Target group: 

This service is available to staff and students at Norwegian universities and university colleges. Researchers in independent research institutes may also gain access to this service, provided that their work is funded by public grants and meets requirements for scientific publication.

Organization of the service: 

Uninett Sigma2 coordinates the e-infrastructure both nationally and internationally, and assists customers in the administration of allocated resources. RFK distributes resources in accordance with priorities and recommendations from Uninett Sigma2. The operation of the services is done by the universities in Oslo, Bergen, Trondheim and Tromsø (the Metacenter) in cooperation.


Compute service is considered available as long as 75% of the total CPU cores are available. Based on this is the availability is 95% over 4 month average.

Notification of planned downtime is 3 weeks.
