Architecture

The NEC Cluster platform (vulcan) consists of several frontend nodes for interactive access (for access details see Access) and several compute nodes of different types for execution of parallel programs. Some parts of the compute nodes comes from the old NEC Cluster laki.

Compute node types installed:

  • Intel Xeon Broadwell, Skylake, CascadeLake
  • AMD Epyc Rome, Genoa
  • different Memory sizes (256GB, 384GB, 512GB, 768GB)
  • Pre-Postprocessing node with very large memory (1.5TB, 3TB)
  • Visualisation/GPU nodes with AMD Radeon Pro WX8200, Nvidia Quadro RTX4000 or Nvidia A30
  • Vector nodes with NEC Aurora TSUBASA CPUs

Features

  • Operating System: Rocky Linux 8
  • Batchsystem: PBSPro
  • node-node interconnect: Infiniband + 10G Ethernet
  • Global Disk 2.2 PB (lustre) for vulcan + 500TB (lustre) for vulcan2
  • Many Software Packages for Development


History

Warning: Hardware Upgrade took place on 2024-05-24
