Using Overlay Networks to Build Operating System Services for Large Scale Grids
Résumé
Using grid resources to execute scientific applications requiring a large amount of computing power is attractive
but not easy from the user point of view. Vigne is a grid operating system designed to provide users with a simplified view of a
grid. Vigne deals with the huge number of nodes in a large-scale grid and with the nodes’ dynamic behavior by using peer-to-peer
overlays as a keystone. In this paper, we show why it is highly desirable to use structured and unstructured peer-to-peer overlays
for building the high-level services of Vigne grid operating system. To show the interest of our approach, we detail the features of
two Vigne services built on top of peer-to-peer overlays. We also present experimental results obtained on the Grid’5000 testbed
showing the scalability of the Vigne infrastructure based on overlays and its practical interest for the implementation of Vigne
distributed services.
