Procurement project HPC A2

The next national HPC and AI/ML Platform

The content on this web page is subject to change. Last updated 21 March 2023.

This project's objective is to acquire and put into operation the next-generation national HPC resource (supercomputer) in the Sigma2 e-infrastructure portfolio. The working name for this resource is A2. A2 will be placed in Lefdal Mine Datacenter, the same location as the new national storage infrastructure (NIRD).

Figure 1: Current Norwegian HPC and Data Storage infrastructure, including sensitive data (TSD) in Oslo. The infrastructure in Tromsø (HPC and storage) will be phased out, and service will be provided from Trondheim (Saga and Betzy), together with the new A2 system in Måløy (Lefdal Mine Datacenter).


The project aims to:

  • replace current HPC machines Fram and Saga and additional usage growth forecast.
  • provide computing capability for AI/ML and scientific applications through GPU/CPU. 
  • procure a system with expandable computing and storage capacity.

Request For Information (RFI)

Aftermarket exploration and defining Sigma2’s needs for the next-generation HPC machine, the project has now published a request for information (RFI). The RFI aims to gather input and information from potential suppliers regarding crucial parts of the procurement documents. The documents are considered drafts, and the final versions are likely to be similar to the drafts unless feedback from the RFI process indicates that changes should be made. 
Sigma2 encourages potential suppliers to use this opportunity to provide feedback, as the possibility to make changes after the invitation to tender has been announced is limited in accordance with the public procurement regulations.

If you wish to contribute to the RFI, please submit your response using the Tendsign tendering tool. Please follow the link below to the publication of the HPC A2 RFI:

Tenders Electronic Daily (TED) HPC A2 RFI

Preliminary timeline

Q1 2023
Publication of RFI

The RFI is published.

H1 2023
Publication of tender

We expect to publish the tender in H1.

H2 2024
New HPC system in production

Our goal is to have the system in production in H2 2024.


HPC systems generally have a life span of approximately 5 years due to declining energy efficiency compared to newer machines, obsolete parts, lack of support, and the arrival of new technology.

Our procurement strategy has traditionally been two-legged, an A- and B-leg where we acquire systems with an offset of 2-3 years.
