Evaluating the performance and intrusiveness of virtual machines for desktop gr...
Domingues, Patrício Rodrigues; Araújo, Filipe; Silva, LuísComunicação apresentada no 3rd Workshop on Desktop Grids and Volunteer Computing Systems, Rome, 2009. ; We experimentally evaluate the performance overhead of the virtual environments VMware Player, QEMU, VirtualPC and VirtualBox on a dual-core machine. Firstly, we assess the performance of a Linux guest OS running on a virtual machine by separately benchmarking the CPU, file I/O and the network bandwidth. The...
Dependability mechanisms for desktop grids
Domingues, Patrício RodriguesTese apresentada à Faculdade de Ciências e Tecnologia da Universidade de Coimbra para otenção do grau de Doutor em Engenharia Informática, orientada por Luís Moura e Silva. ; It is a well-known fact that most of the computing power spread over the Internet simply goes unused, with CPU and other resources sitting idle most of the time: on average less than 5% of the CPU time is effectively used. Desktop grids a...
