The latest phase of the Berzelius service is Berzelius Hopper. Berzelius Hopper consist of 16 NVIDIA® DGX-H200 compute nodes supplied by Eviden and 8 CPU nodes also supplied by Eviden.
The DGX H200 are equiped with 8 NVIDIA® H200 141GB GPUs, 2 Intel® 8480C CPUs, and 2.1 TB RAM. The CPU nodes are each equipped with 2 AMD Epyc™ 9534 CPUs, 1.1 TB RAM and 6.4 TB of local NVMe SSD storage. The DGX H200 nodes are connected to a fast interconnect with 8x NVIDIA® Mellanox® NDR per DGX in a non-blocking fat-tree topology. This is a separate interconnect from that which connects the DGX A100 nodes in Berzelius Ampere.
All nodes have a local disk where applications can store temporary files. The size of this disk (available to jobs as `/scratch/local`) is 30 TB on H200 nodes, and 6.4 TB on CPU nodes, and is shared between all jobs using the node.
Berzelius Hopper is accessed through a new set of login nodes separate from those in the original Berzelius installation and also has new servers for other supporting tasks.
Berzelius Hopper is currently in a testpilot phase before being released for new projects in SUPR.

Open Round
At this moment, you can apply for access to this resource in the following round:
LiU Berzelius 2025
Apply to this round for a project on the Berzelius SuperPOD at NSC. Berzelius is not a NAISS system. It is a direct donation to NSC from the Knut and Alice Wallenberg foundation (KAW). Projects with financial support from KAW should have priority according to the donation letter.
To be granted resources on Berzelius, both the Principal Investigator (PI) — defined here as the main applicant in SUPR — and the project must meet the conditions stated here.
Applications are normally evaluated during the last week each month
