Executive Summary

In the last ten years host virtualization has brought a revolution in the way almost every activity related to information technology is thought of and performed. The use of virtualization for HPC and HTC computing, while eagerly desired, has probably been one of the last steps of this revolution, the performance loss due to the hardware abstraction layer being the cause that slowed down a process that has been much faster in other fields. Now-a-days the widespread diffusion of virtualization and of new virtualization techniques seem to have helped breaking this last barrier and virtual host computing infrastructures for HPC and HTC are found in many data centers.
