Hardware details

The VUB Hydra cluster contains a mix of nodes with AMD and Intel processors and different interconnects in different sections of the cluster. The cluster also contains a number of nodes with NVIDIA GPUs.

Login nodes:

  • login.hpc.vub.ac.be or hydra.vub.ac.be
  • Use one of those hostnames if you read vsc.login.node in the documentation and want to connect to this login node.
