Access to Tetralith at NSC.

Resource	Centre	Total Requested	Upper Limit	Default Storage	Available	Unit	Note
Tetralith	NSC	469	5		200	x 1000 core-h/month
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.
Centre Storage	NSC	24 000	—	500	60 000	GiB
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.
