Energy efficiency and high computing power are basic design considerations across modern-day computing solutions due to different concerns such as system performance, operational cost, and environmental issues. Desktop Grid and Volunteer Computing System (DGVCS) so called opportunistic infrastructures offer computational power at low cost focused on(More)
In this paper, we address energy savings on a Cloud-based opportunistic infrastructure. The infrastructure implements opportunis-tic design concepts to provide basic services, such as virtual CPUs, RAM and Disk while profiting from unused capabilities of desktop computer laboratories in a non-intrusive way. We consider the problem of virtual machines(More)
Large-scale computing platforms and current networking technologies enable sharing, selection, and aggregation of highly heterogeneous resources for solving complex real problems. Opportunistic grids are distributed platforms built out of the available resources (volunteers or donors) of an existing hardware platform that harvest the computing power of(More)
