.. _Hydra hardware: Hydra hardware =============== The VUB Hydra cluster is an heterogeneous cluster with a mixture of nodes with varied hardware. The majority of nodes are non-GPU nodes for generic multi-purpose compute, they are distributed in partitions depending on their CPU microarchitectures and network interconnects. The cluster also contains a number of nodes with NVIDIA GPUs, which are also distributed in partitions depending on their GPU generation.
