Utilizing the EGEE infrastructure for desktop grids

Today basically two grid concepts rule the world: service grids and desktop grids. Service grids offer an infrastructure for grid users, thus require notable management to keep the service running. On the other hand, desktop grids aim to utilize free CPU cycles of cheap desktop PCs, are easy to set up, but the availability towards users is limited compared to the service grid. The aim of the EDGeS project is to create an integrated infrastructure that gathers the advantages of the two grid concepts. A building block of this infrastructure is bridging between the different grid types. In the paper we focus on bridging from desktop grids towards service grids, i.e. making desktop grids able to utilize free service grid resources
