New GPU Cluster JUDGE

In February, the new IBM iDataPlex GPU cluster JUDGE (Juelich Dedicated GPU Environment) will be available for production jobs. The cluster consists of 54 compute nodes, 2 login and service nodes and 2 GPFS gateway nodes. Each compute node is equipped with 2 Intel Xeon X5650 (Westmere) 6 core processors of 2.66 Ghz, 96 GB main memory and additionally 2 NVIDIA Tesla M2050 GPU (Fermi) 3 GB memory. All cluster nodes are connected via Infiniband. The user file system is remote GPFS imported from the Jülich storage cluster JUST via two gateway nodes with routing functionality from 10G Ethernet connection to Infiniband. JUDGE will be used by Forschungszentrum Jülich for simulation projects. The system will be advantageous for applications that need a large main memory and can profit from the usage of graphic processors. There will be a special course for GPU programming in March.
