To apply, you must be a scientist in Swedish academia, at least at the level of assistant professor.
Deadlines and Decisions
Proposals are processed monthly during the year. Note that staff will be on vacation during the summer and Christmas and New Year holidays. Thus, July and December have different schedules than other months.

The Alvis resource is dedicated for research in and research using AI/ML techniques.
For general use of GPU:s instead use Dardel GPU.
Allocations on Alvis will be scaled and transferred to the new NAISS system Arrhenius. It is NAISS's best estimate now that this will occur early in 2026. More information will be announced as procurement and installation of Arrhenius progresses.
The Alvis cluster is a national NAISS resource dedicated to Artificial Intelligence and
Machine Learning research.
Note: Significant generation of training data is expected to be done elsewhere.
The system is built around Graphical Processing Units
(GPUs) accelerator cards. The first phase of the resource has 160 NVIDIA T4, 44
V100, and 4 A100 GPUs. The second phase is based on 340 NVIDIA A40 and 336
A100 GPUs.

Projects will receive a default 500 GiB storage allocation on Centre Storage at NSC. If you need more storage, please apply for a Storage project and decline default storage from this compute proposal.
Allocations on Tetralith will be scaled and transferred to the new NAISS system Arrhenius. It is NAISS's best estimate now that this will occur late in 2025. More information will be announced as procurement and installation of Arrhenius progresses.
Tetralith is a general computational resource hosted by NSC at Linköping University.
Tetralith servers have two Intel Xeon Gold 6130 processors, providing 32 cores per server. 1844 of the servers are equipped with 96 GiB of primary memory and 64 servers with 384 GiB. All servers are interconnected with a 100 Gbit/s Intel Omni- Path network which is also used to connect the existing storage. Each server has a local SSD disk for ephemeral storage (approx. 200GiB per thin node, 900GiB per fat node). An IBM Spectrum Scale system comprises the centre storage. 170 of the Tetralith nodes are equipped with one NVIDIA Tesla T4 GPU each as well as a high- performance NVMe SSD scratch disk of 2TB.

These GPUs are not nVIDIA GPUs but rather AMD GPUs, so if your software runs using CUDA, a certain amount of conversion of the code is needed.
You can read information about this at https://www.lumi-supercomputer.eu/preparing-codes-for-lumi-converting-cuda-applications-to-hip/
Reporting on GPU consumption on Dardel is not working yet.
Dardel-GPU is the accelerated partition based on AMD’s Instinct MI250X GPU of the Cray EX system from Hewlett Packard Enterprise. It has an accompanying Lustre storage system.
The nodes are interconnected using Slingshot HPC Ethernet.

Allocations on Cloud will be scaled and transferred to the new NAISS system Arrhenius. It is NAISS's best estimate now that this will occur early in 2026. More information will be announced as procurement and installation of Arrhenius progresses.
Swedish Science Cloud (SSC) is a large-scale, geographically distributed OpenStack cloud Infrastructure as a Service (IaaS), intended for Swedish academic research provided by NAISS.
It is available free of charge to researchers at Swedish higher education institutions through open application procedures.
The SSC resources are not meant to be a replacement for NAISS supercomputing resources (HPC clusters). Rather, it should be seen as a complement, offering advanced functionality to users who need more flexible access to resources (for example more control over the operating systems and software environments), want to develop software as a service, or want to explore recent technology such as for “Big Data” (e.g. Apache Hadoop/Spark) or IoT applications.
