VUB-HPC is a member of the Vlaams Supercomputer Centrum (VSC), a partnership between the five Flemish universities and their university associations to provide HPC resources to the academic and industrial community in Flanders.
As a member of VSC, all researchers in VUB and UZ Brussel can access all Tier-2 clusters in the VSC network.
Full list of Tier-2 clusters is available in VSCdocTier-2 Hardware
Hydra is the local VSC Tier-2 cluster managed by VUB-HPC. It is a general purpose heterogeneous cluster that is maintained under a policy of permanent upgrades. Therefore, over the years it has gained several features:
3000+ CPU cores for generic compute
20+ NVIDIA data center GPUs
High-memory node with 1.5 TB of RAM
Fast InfiniBand Interconnect (EDR)
Detailed hardware information is available in VSCdocHydra Hardware
Tier-1 clusters offer computational resources in a bigger scale to tackle bigger problems
large parallel computing jobs that require a high-bandwidth low-latency interconnect
large arrays of jobs with a multitude of small independent tasks
large arrays of jobs that require the use of 1 or more GPUs
As a member of VSC, all researchers in VUB and UZ Brussel can request access to any of the Tier-1 clusters in the VSC network. Resources in Tier-1 are granted to research projects that need the large scale HPC and can efficiently use its computational resources. More information in Getting Access.
The current Tier-1 cluster, VSCdocHortense, consists of both CPU-only and GPU nodes.
