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.
Proposals will be evaluated within a few working days. Projects will receive a default 500 GiB storage allocation on Centre Storage at NSC. For additional storage, please apply for a Storage project.
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.
Dardel is the new cluster at PDC and will be available end of November 2021
Dardel is the new cluster at PDC and will be available end of November 2021. Projects on Dardel will start 2021-12-01 at the earliest
Dardel is a Cray EX system from Hewlett Packard Enterprise, based on AMD EPYC processors with an accompanying Lustre storage system.
The nodes are interconnected using Slingshot HPC Ethernet.

UPPMAX compute resource. Mounts the Crex file system.
Projects will receive a default 128 GB storage allocation. For additional storage, please apply for a Storage project.
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.
