Development projects
In collaboration with DeiC, KOR is to ensure that Denmark’s long-standing tradition of operating and developing registers and databases is supported as effectively as possible by new technological opportunities, enabling Denmark to maintain an international leading position in register-based research.
On this basis, KOR initiates development projects that will create new opportunities for researchers and exploit the potential of registers, historical data and new technology even better. The latest and current development projects have focused on the establishment of new registers and on linking data from DST's security zone with the possibilities for complex calculations on the national supercomputers (i.e. High-Performance Computing (HPC) under DeiC).
API connection between Statistics Denmark and national HPC facilities
From December 4, 2025, Danish researchers can analyze sensitive data from Statistics Denmark (DST) on a number of national HPC facilities.
This is done through a new so-called API (application programming interface) that connects the Danish Data Window with the country's HPC (High Performance Computing) facilities. The solution has been developed and launched by Statistics Denmark in collaboration with DeiC and the universities' HPC environments to ensure Danish researchers flexible and secure access to advanced data processing.
New technical bridge between DST and the universities
As an authorized institution under DST's microdata schemes, data is currently made available to certified users who order via the Danish Data Window. All data is pseudonymized before researchers can access it and use it in their research.
With the new API, pseudonymized data can then be processed at an approved HPC facility where the researcher has been granted or purchased computing time. Data processing then takes place at the HPC facility, where the researcher has access to highly specialized hardware, complex software solutions and technical support. Once the analysis is complete, the results must be returned to DST for approval before the researcher can download them for further use.
DTU Computerome is the first facility to enter into an agreement with DST for this solution and from December 4, it will be possible to create projects via these HPC facilities. GenomeDK is also in the process of integration, and this page will be updated with information when the solution is integrated.
About the project
The solution has been developed by Statistics Denmark in close collaboration with DeiC and the universities' HPC centers at the request of the Coordinating Body for Register Research (KOR). The goal has been one standardized solution that all HPC centers can connect to.
DeiC has had a central role in the technical collaboration with the HPC centers and has contributed with development and testing of the connection between the API and the HPC facilities, including a proof-of-concept that the centers could adapt locally. The technical implementation of the API and the integration with Denmark's Data Window was provided by Copenhagen Data.
