Architecture

The NEC Cluster platform (laki and laki2) 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.


Compute node types installed:

  • Intel Xeon 5560 (nehalem)
  • Intel Xeon E5-2670 (Sandy Bridge)
  • AMD Opteron 6238 (interlagos)
  • Nvidia Tesla S1070 (consisting of C1060 devices)
  • Large Memory nodes (144GB, 256GB)
  • Pre-Postprocessing node with very large memory (1TB)
  • Visualisation nodes with Nvidia Quadro FX5800
  • Different memory nodes (12GB, 24GB, 32GB, 48GB, 64GB)


Features

  • Operating System: ScientificLinux 6.4 (internal test was done on Windows HPC Server 2008)
  • Batchsystem: Torque/Moab
  • node-node interconnect: Infiniband + GigE
  • Global Disk 240 TB (lustre) for laki + 110TB (lustre) for laki2
  • Many Software Packages for Development
