Hardware
- 700 compute nodes are of type NEC HPC-144 Rb-1 Server (see NEC Products)
- 2x Intel Xeon E5560 "Nehalem", 2.80 GHz, 8MB Cache, FSB 1333 MHz, 4 core, 8 threads (5000 Sequence specifications, 5500)
- 32 compute nodes of them have additional Nvidia Tesla S1070 GPU's installed.
- network: InfiniBand Double Data Rate
- switches for interconnect: Voltaire Grid Director 4036 QDR
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 GPU (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
