In the European model for HPC, a distinction is made between three levels:
Tier-2: the computing capacity that is available at research institutions
Tier-1: the computing capacity that exceeds the capacity of an institution in terms of needs and costs and which is provided at the level of a region or country
Tier-0: the very large-scale computing infrastructure
Tier-3 includes single computers (your own infrastructure)
The VSC focuses mainly on Tier-2 and Tier-1 but also motivates audiences to transfer from Tier-3 to Tier 2. We also support current users of HPC infrastructure to move from Tier 1 towards Tier 0 (e.g., by supporting our users in preparing for PRACE and LUMI project calls).
