CRS4 offers support for research to the scientific community through the High Performance Computing and its applications, thanks to a state of the art computer center. Its staff is formed of highly trained specialist who assist researchers in using the technology infrastructure. The CRS4 computing power is about 137 TFlops and divided as follows:

• GPU Nvidia Kepler  90 TFlops
• HP Cluster 34,6 TFlops (low & medium latency) 
• IBM Cell 2,7 TFlops
• Sun Cluster 3 TFlops
• Tesla cluster
• GPU NVidia cluster
• FPGA Maxeler
• IBM Cluster and other resources 3 TFlops

The most recent  CRS4 high performance computing purchase is a small size installation, composed by 10 nodes with 20 of the latest generation Nvidia Kepler GPU accelerator. This cluster has extremelly low latency connections (Infiniband QDR), and each node mounts 64 GB of RAM for 90 TFlops of theoretical computing power.

The center hosts several computing cluster including a medium installation, composed by 400 nodes dual quadcore, 3200 computation units in total.

This cluster is divided into two subsystems characterized by the type of network connection. The most important subsystem has a low latency network connections / broadband connection to the other subsystem has average latency. A small section of the nodes is dedicated to the provision of services for the two clusters.
These service nodes have network connections at both low and medium latency.

In detail, the cluster is divided as follows:

• 256 compute nodes with connections Infiniband / Ethernet - Low Latency Cluster
• 128 compute nodes with Ethernet Cluster of medium-latency
• 16 service nodes with FibreChannel connection / Infiniband / Ethernet - Cluster service nodes.

All the nodes computation, both InfiniBand and Ethernet are HP BL460c blades. The service nodes are HP BL480c blades.
