Galileo (supercomputer)
Galileo is a 1.1petaFLOPS supercomputer located at CINECA in Bologna, Italy.

History
GALILEO is available in Cineca since January 2015, in full production since February, the 2-nd, sponsored by the Ministry of Education, Universities and Research (Italy), the Istituto Nazionale di Fisica Nucleare and the University of Milano-Bicocca. It is the Italian National Tier-1 HPC machine, devoted to scientific computing as well as technical oriented applications. Galileo is also available to European researchers as a Tier-1 system of the PRACE 
 infrastructure.

In June 2015, Galileo reached the 105-th position on the TOP500 list of fastest supercomputers in the world.

In the Green500 list of top supercomputers. Galileo reached the 389-th position in their benchmark, the system tested at 242.17 MFLOPS/W (Performance per watt).

Technical details 
Galileo is an IBM Linux infiniband cluster,  with a NeXtScale architecture. It is made of 516 compute nodes. Each node contains 2x8-cores Intel Haswell processors (2.40 GHz) and a shared memory of 128 GB. The internal network is Infiniband with 4xQDR switches. The cluster is accessible though 8 login nodes, also user for visualization, reachable via ssh at the address login.galileo.cineca.it. The login nodes are equipped with 2 nVidia K40 GPU each. On the cluster there are also 8 service nodes NX360M5 for I/O and management.
The Operating system for both executable and login nodes is CentOS 7.0.

Galileo is an heterogeneous hybrid cluster: 359 nodes are equipped with Intel accelerators (Intel Phi 7120p), 2 accelerators per node for a total of 768 Phi in the system; 40 nodes are equipped with nVidia accelerators (nVidia K80), 2 accelerators per node for a total of 80 K80 in the system.
