Cloud

Resource Centre Short Description
Cloud SSC Swedish Science Cloud provides Infrastructure as a Service; IaaS

Swedish Science Cloud (SSC) is a geographically distributed OpenStack cloud Infrastructure as a Service (IaaS), intended for Swedish academic research provided by NAISS.

It is available free of charge to researchers at Swedish higher education institutions through open application procedures.

The SSC resources are not meant to be a replacement for NAISS supercomputing resources (HPC clusters). Rather, it should be seen as a complement, offering advanced functionality to users who need more flexible access to resources (for example more control over the operating systems and software environments), want to develop software as a service, or want to explore recent technology such as for “Big Data” (e.g. Apache Hadoop/Spark) or IoT applications.

Examples of applications that must run in the normal HPC clusters since the SSC isn't built for those purposes.

  • AI/LLM/Deep Learning and other applications relying on GPU resources cannot be run in the SSC due to the limited access to GPU's.
  • Applications assuming high performance or large volumes of storage, network, or cores.
  • Benchmarking will not perform well within SSC due to performance limitations.
  • SSC isn't classified for Sensitive data, those project MUST use Cluster system for sensitive data within NAISS.

Other National Resources

Resources funded outside of NAISS but which are nationally available, in some cases under special conditions. See conditions for access under each resource.

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.
