Viking

Viking is the University’s high-performance computing facility for research projects. It’s a large cluster of interconnected computers running Linux.

Viking is hosted in a carbon-neutral data centre, EcoDataCenter. It's powered using 100% renewable energies and utilises heat recovery from hardware. From this, it transforms surplus energy into wood pellets – a clean, sustainable and renewable fuel source. This means the environmental impact of computational research has been accounted for and is reduced.

Key features

  • High memory capacity handles intensive datasets.
  • Large storage delivers fast processing speeds.
  • Hosted in a carbon-neutral data centre powered by 100% renewable energy, utilising heat recovery and sustainable materials to minimise the environmental impact of computational research. 
  • Award winning: The University was recently awarded the Sustainable Digital Project or Initiative Award at the UCISA awards, with the move to EcoDataCenter forming a key part of the submission.

Spec list

  • 134 compute nodes: each with 96 CPU cores per node (two processors each with 48 cores), 512GB memory, and AMD EPYC3 7643 processor generation.
  • Three high memory nodes: one with 4TB and two with 2TB memory
  • 60 graphics processing units (GPU): 48× NVIDIA A40 and 12× NVIDIA H100.
  • Over 1.7PB storage: 1.5PB scratch space and 215TB usable NVMe.
  • 100 Gb/s interconnect: with Intel omni-path architecture (OPA).
