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.
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 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.
Project storage for NAISS as well as LiU Local projects with compute allocations on resources hosted by NSC.
Centre Storage @ NSC is designed for fast access from compute resources at NSC. It consists of one IBM ESS GL6S building block and one IBM ESS 5000 SC4 building block.
In total there are 946 spinning hard disks and a small number of NVRAM devices and SSDs which act as a cache to speed up small writes. The total disk space that is usable for storing files is approximately 6.9 PiB.

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
