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:

  • Sandybridge, Haswell, Skylake
  • different Memory nodes (32GB, 64GB, 128GB, 256GB, 384GB)
  • Pre-Postprocessing node with very large memory (1TB)
  • Visualisation/GPU nodes with Nvidia Quadro FX5800 or Nvidia Tesla P100


Features

  • Operating System: Centos 7
  • Batchsystem: PBSPro
  • node-node interconnect: Infiniband + GigE
  • Global Disk 500 TB (lustre) for vulcan + 500TB (lustre) for vulcan2
  • Many Software Packages for Development
