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 S1070 (consisting of C1060 devices)


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
