In close collaboration our Resource Allocation Committee, we have successfully completed the evaluation of research applications for the second resource allocation period of 2025.
As we approach the end of 2025, the Sigma2 supercomputing and data storage resources are supporting more than 2000 active e-infrastructure users.
Over 670 million CPU hours have been allocated to approximately 350 research projects, while more than 185 projects have been granted nearly 34 PB of storage in total on the national e-infrastructure for high-performance computing and scientific data.
The HPC customers from the scientific fields of physics and computational fluid dynamics are the largest group of researchers in need of computing resources, followed by geosciences and chemistry. The size of computing projects in terms of consumed CPU hours has grown year after year.
In the ongoing allocation period, the largest individual computation project is Solar Atmospheric Modelling, led by Professor Mats Carlsson, at the University of Oslo. The astrophysics project will consume no less than 154 million core hours in the ongoing allocation period.
HPC Top 10 projects
NIRD Top 10 projects
A computer science project focused on training very large language models is, by far, the largest user of the national storage resources. Beyond this, there is significant representation from data-driven disciplines such as climate and earth sciences. This is largely attributed to Norwegian climate researchers contributing to the UN’s Intergovernmental Panel on Climate Change (IPCC) through CMIP simulations.
Did you miss the deadline?
Applications submitted after the application deadline for the new period are case handled after the period has started. Within a period, all applications are handled continuously. However, old projects applying after the deadline or after the period has started, receive lower queue priority (cost command non-pri quota).
If a project exhausts its allocations before the end of the ongoing allocation period, the project manager can submit a request for an extra allocation for the remainder of the period. There are no deadlines for such requests. Requests for extra allocations are subject to available capacity on the facilities. This also applies to proposals submitted outside regular calls.
