For Academia


Who is entitled to an HPC account?

The HPC centre is open to all researchers in Denmark, and all academic users can benefit from the available resources under the same conditions.

Proposers for any kind of allocation schemes must hold at least the position of postdoc within their institution. PhD students request access in consultation with, and under the auspices of, their supervisor.

Access to the facility is not free. All academic users, independently of their host institution, pay the same price. This allows all Danish researchers to take advantage equally of the DeiC contribution to the national facility at SDU.

Users are billed according to how many node hours they could be allocated on Abacus 2.0. This means that node hours not used by the applicant within the corresponding time frame will not be refunded. However, up to 20% of the original quota for a period will automatically be carried over to the next period, if the project has not used all available resources.

Rates for each node type can be found here.

Three major Danish universities — AAU, AU and SDU — have already committed to buy HPC resources for a total amount of 21M DKK.

AU has committed to buy 5M DKK over 4 years (March 2015-February 2019).

AAU has committed to buy 0.25M DKK resources every year over 4 years (March 2015-February 2019).

The Rector of SDU has set aside 15M DKK for the period 2015-2018 to (co)finance access to computational resources on the HPC facility by SDU researchers. 

How do I request an HPC account?

All researchers – except researchers affiliated with AU and AAU- need to request their HPC account online on the Abacus website.

Researchers affiliated to AU and AAU request their local HPC coordinator for access to the facility.

AU researchers need to contact:  Niels Carl Hansen,, tel. +4587155401 or mobile +45 60202635

AAU researchers need to contact: Josva Kleist, , mobile +45 31621403                   

The allocation of the available resources follows a regular schedule of four month periods, called “allocation periods”. The three yearly allocation periods are: 1st of March to 30th of June, 1st of July to 31st of October, 1st of November to last day of February.

You can send in requests for access to Abacus 2.0 for the next four-month window:

Time frame: November 1, 2017 to February 28, 2017

  1. Fill out and submit the request form:  Request access here

You can request for three different types of allocation: (see below)

Please be aware that HPC resources are allocated in terms of 1.000 of node-hours.

As part of the allocated resources, access to the HPC facility storage system is provided. Please provide the storage requirements for your request in the form.

  1. Your request will be processed.  

Requests will be accommodated in relation to the resources available and the overall technical feasibility of the project.

  1. In the week preceeding the start of the new allocation period you will receive an email from the HPC Coordinator at SDU informing you of the resources allocated to your project.

A consequence of the limited resources available, even high-quality projects might not be allocated resources for the current allocation period, but could be allocated for the next allocation period for these projects, if deemed appropriate by the requester/applicant, so as to ensure access without the need to resubmit a request/application.

  1. You will receive a separate activation email with a link to your account.

Test Projects

Test projects are those which are exploratory or preliminary in nature and which only require a limited amount of resources. Test projects can apply for a maximum of 2000 node hours on fat and GPU nodes and a maximum of 10000 node hours on slim nodes and they are limited to one allocation period in time and one kind of nodes. The SDU Access Committee will facilitate the allocation of resources to test projects in the prioritisation process as much as possible to allow access of new users to the HPC infrastructure.

Regular Projects

Regular project provide access to HPC resources for one allocation period. The access period can be extended to more consecutive allocation periods up to a maximum of three periods in case of the need for a prolonged access is justified. Access for regular projects, or simply projects, is intended for a specific activity. A description of this activity and a reasoned plan for the HPC resources needed is required as part of the application.

Long Term Access

Research groups with experience in HPC computing, which require continued access to HPC resources, can apply for long term access. This kind of allocation provide access for three allocation periods (one year) intended for wider research programs which make extensive use of HPC resources. Applicants are required to have a track-record of research based on the use of HPC platforms.

Pilot Projects

Researchers at Danish universities may also submit a call of interest for a project to become a DeIC National eScience Pilot Project.

The advantages of using the Abacus 2.0 supercomputer at SDU

  • Low price: Abacus 2.0 is a power efficient machine and thanks to the low administrative overhead, it is also a cost effective installation. Researchers in Denmark can additionally benefit from an overall ~35% discount on the total price thanks to financial support by DeIC.
  • Available now: Abacus 2.0 is available right now, without the need to long waiting time to procure the hardware and uncertainties on the final price.
  • Scalable: In every allocation period of 4 months, researchers can buy exactly what they need. This means no need for big initial investments. DeIC is also offering pilot projects for researchers which come with full user support and are completely free of charge (see below for details).
  • Flexible: Abacus 2.0 is a very flexible system, which can accommodate a very large range of research and technical applications. Built with 3 different kinds of computing nodes, and a very fast local and distributed storage system, you can pick the solution which better fits your needs.
  • Ownership: PIs have full control on the resources of your project running on Abacus 2.0. Using the credentials from your own institutions, you can add and remove collaborators to your project and monitor the overall activity from your own online project area.
  • Easy: The user environment of the Abacus 2.0 supercomputer is built around a modern modular system and can easily integrate with more specific softwares, if required by particular projects.
  • Efficient and reliable: Jobs running on Abacus 2.0, are managed by a modern and flexible queue system, with a policy designed to offer low waiting times and a high turnaround. Interactive jobs are also possible on all of the three different kinds of computing nodes (slim, fat and GPU).
