Hardware and Architecture
The HLRS DGRID Cluster platform consists of one front node for interactive access (forntend.dgrid.hlrs.de) and serveral compute nodes for execution of parallel programs.
Two different compute node CPU architecture types are installed:
- IBM cell
- Intel Xeon 5150 (woodcrest)
Features
- Operating System: ScientificLinux 4.4 on Intel based nodes
- Operating System: Fedora Core5 on cell based nodes
- Batchsystem: Torque/Maui
- node-node interconnect: Infiniband + GigE
- Local Disk for scratch on each node
- Global Disk 100 TB
- GPFS
- OpenMPI
- Compiler: Intel, GCC, Java
