Who is using our supercomputers?


In close collaboration with the Research Allocation Committee, we have now finalised the evaluation of research applications for the 2nd resource period in 2021.

Near the end of 2021, we have more than 2000 active e-infrastructure users of the NRIS supercomputing and data storage resources. More than 700 million CPU hours are allocated to about 400 different research projects, while more than 150 projects have received nearly 12 PB in total on the national e-infrastructure resources for High-Performance Computing and scientific data.

The number of allocations requested for both HPC and storage indicates that the resource demand continues to increase. Researchers in climate modelling, life sciences, materials technology, physics, chemistry, earth science and language technology have a wide-ranging need for reliable computing power and data storage.  

Earth science and physics consume the most computer time

The HPC customers from the scientific fields of earth science and biosciences are the largest group of researchers in need of computing resources. 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 132 million core hours in the ongoing allocation period. All NRIS` top 25 projects are in the millions range in CPU-hours of computing projects.

Climate research on NIRD 

Climate and earth science are data-driven disciplines and by far the largest users of the national storage, followed by computational fluid dynamics and bioinformatics.

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.
