| 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
