Hardware NEC Nehalem Cluster

Architecture

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


Compute node CPU architecture types installed:

  • Intel Xeon 5560 (nehalem)
  • Nvidia Tesla S870 GPU


Features

  • Operating System: ScientificLinux 5.3 on Intel based nodes
  • Batchsystem: Torque/Maui/Moab
  • node-node interconnect: Infiniband + GigE
  • Global Disk 60 TB (lustre)
  • OpenMPI
  • Compiler: Intel, GCC, Java
