Hardware

Architecture

The NEC Nehalem Cluster platform consists of several frontend nodes for interactive access (for access details see Access) and several compute nodes for execution of parallel programs.


Compute node CPU architecture types installed:

  • Intel Xeon 5560 (nehalem)
  • Nvidia Tesla C1070 GPU


Features

  • Operating System: ScientificLinux 5.3 (internal test on Windows HPC Server 2008)
  • Batchsystem: Torque/Maui/Moab
  • node-node interconnect: Infiniband + GigE
  • Global Disk 60 TB (lustre)
  • OpenMPI
  • Compiler: Intel, GCC, Java
