SYSTEM

Description The SAGA Cluster has HP SL390 G7 servers and NVIDIA GPUs. It is a heterogeneous system consisting of 320 nodes with Intel Xeon E5530 and Intel Xeon E5645 CPUs, and C2070 and M2090 GPUs. The system has 153600 CUDA Cores on NVIDIA Tesla M2090 GPGPU and 1416 Intel Xeon Westmere-EP cores alongwith WIPRO servers (202 nos) of Intel Xeon Westmere and Nehalem cores, each with 2 numbers of NVIDIA GPGPU C2070 per server.
Network40 Gbps Infiniband QDR interconnect
NodeThe system has three kinds of nodes:
1. 185 nodes (WIPRO Z24XX(ii) model Servers) consist of dual quad-core Intel Xeon E5530 CPU @ 2.4 GHz, and dual C2070 GPUs.
2. 17 nodes (WIPRO Z24XX(ii) model Servers) consist of dual hexa-core Intel Xeon E5645 CPU @ 2.4 GHz, and dual C2070 GPUs.
3. 118 nodes (HP SL390 G7 servers) consist of dual hexa-core Intel Xeon E5645 CPU @ 2.4 GHz, and dual M2090 GPUs.
