Available Unit Note
Kebnekaise HPC2N 200 2 000 x 1000 core-h/month Proposals will be evaluated at the end of each month.
Kebnekaise is a heterogeneous computing resource consisting of:


  1. Access to the Large Memory nodes are handled through the 'Kebnekaise Large Memory' resource.
  2. Requests for GPU and KNL nodes should be explicitly specified in the user's proposal.
  3. GPU nodes and the KNL nodes are charged differently than ordinary computing nodes.
Kebnekaise Large Memory HPC2N 10 50 x 1000 core-h/month Proposals will be evaluated at the end of each month.
To get access to the Kebnekaise Large Memory resource the proposal must clearly show a need for it, including expected memory size required, and a reason for why the normal nodes are not suitable.

This resource is for access to the 'Large Memory nodes' in Kebnekaise. For standard, GPU and KNL nodes see resource 'Kebnekaise'.

Kebnekaise is a heterogeneous computing resource consisting of:
Tetralith NSC 200 11 500 x 1000 core-h/month Applications are normally evaluated during the last week each month.
Submit your proposal at least one week before the end of a month to be considered for an allocation from the first of the following month. Received proposals will be evaluated against each other and time that become available as project ends at the end of a month will be allocated to the proposed projects accordingly.

Tetralith,, runs a CentOS 7 version of the NSC Cluster Software Environment. Use the workload manager Slurm (e.g sbatch, interactive, ...) to submit your jobs. ThinLinc is available on the login nodes. Applications are selected using "module". All Tetralith compute nodes have 32 CPU cores. There is 1832 "thin" nodes with 96 GiB of primary memory (RAM) and 60 "fat" nodes with 384 GiB. Each compute node have a local SSD disk where applications can store temporary files (approximately 200 GiB per thin node, 900 GiB per fat node). All Tetralith nodes are interconnected with a 100 Gbps Intel Omni-Path network which is also used to connect to the existing storage. There are 170 nodes in Tetralith equipped with one NVIDIA Tesla T4 GPU each as well as an updated, high-performance NVMe SSD scratch disk of 2TB. The nodes are regular Tetralith thin nodes which have been retrofitted with the GPUs and disks, and are accessible to all of Tetralith's users.
Beskow PDC 200 7 800 x 1000 core-h/month A small allocation on Tegner will be appended for allocations that are granted on Beskow.
A small allocation on Tegner for pre/post-processing will be appended for allocations that are granted on Beskow. Any data belonging to the project needs to be moved from the users' 'nobackup' directories and into the project directory as soon as possible. 30 days after the storage allocation starts, the 25GiB quota will be enforced in the 'nobackup' directories. More information about project directories in Klemming can be found at
Tegner PDC 140 x 1000 core-h/month
Tegner is the pre/post processing cluster for Beskow
Rackham UPPMAX 200 2 000 x 1000 core-h/month
Rackham provides 9720 cores in the form of 486 nodes with two 10-core Intel Xeon V4 CPUs each. 4 fat nodes have 1 TB of memory, 32 fat nodes have 256 GB, and the rest have 128 GB. The interconnect is Infiniband.
