overview


SeARCH (Services and Advanced Research Computing with HTC/HPC clusters) is a computing infrastructure based on the Rocks platform, having 800 cores distributed over 54 nodes with dual Intel Xeon processor, essentially divided in two segments.
A relatively homogeneous segment supported on Ivy Bridge processors (E5-2650v2, E5-2670v2, E5-2695v29), providing 504 cores, distributed over 28 nodes with the following configuration: 64GB RAM, 240GB SSD, network connections of 1 and 10Gb (Myrinet).
Another segment, more heterogeneous, based on Nehalem processors (E5520, X5650, E5649) consist of 16 nodes, corresponding to 176 cores. The individual configurations of these nodes are: RAM 8, 12 and 48GB; Gigabit Ethernet (10Gb Mirynet also in 4 knots); SATA drives with different capacities.

The cluster also has 21 accelerators distributed over 12 nodes: 9 Intel Xeon Phi (8×7120 1×5110 and) and 12 NVIDIA Tesla (5x K20m Kepler, Fermi M2090 1x, 2x and 4x Fermi M2070 Fermi C2050).

SeARCH integrates a distributed storage system of 98TB, consisting of Dot Hill SAN with 40TB of raw capacity, connected by 16Gb Fibre Channel links to 4 dual-Xeon nodes, each with 12TB of raw capacity. These nodes also facilitate access to the entire storage space via NFS and GlusterFS.
