Dynamic Distribution and Execution of Tasks in Pervasive Grids

Grid computing and pervasive computing have rapidly emerged and affirmed respectively as the paradigm for high performance computing and the paradigm for user-friendly computing. The conjunction of such paradigms are now generating a new one, the pervasive grid computing, which aims at extending classic grids with characteristics of pervasive computing like spontaneous and transparent integration of mobile devices, context-awareness, pro-activity, and so on. In this paper, we present a software infrastructure for integrating mobile devices as active resources in a grid. In particular, it has been developed a service able to dynamically distribute and execute user's tasks on a grid of mobile and fixed devices. Mobile devices participate to the grid in a way completely transparent to their owners, hence the computational power is given without any configuration operation and in a reliable way. As well, users willing of executing their applications directly submit their code without caring of choosing and allocating resources of the grid.
