The minimisation of the total cost of ownership is hard to be faced by the owners of large
scale computing systems, without affecting negatively the quality of service for the users …

This paper proposes a heuristic to improve the analysis of supercomputers error logs. The
heuristic is able to estimate the error on the measurement induced by the clustering process …

Even though the Italian Grid Infrastructure (IGI) is a general purpose distributed platform, in
the past it has been used mainly for serial computations. Parallel applications have been …

This work presents a resource allocation algorithm that considers the characteristics of
regular applications to choose the subset of processors, accelerators, and networks that …

Large data centers have costs of implementation and management generally very high and
a significant part of these costs are related to energy consumption. In addition, Governments …

In recent years, some strategies (eg, server consolidation by means of virtualisation
techniques) helped the managers of large Information Technology (IT) infrastructures to limit …

Ad hoc networks have been extensively deployed in recent years. In such networks,
obtaining a high efficiency is difficult to achieve due to mobility. Many routing approaches …
