Resource Management in the Entropia System

Resource management for desktop Grids is particularly challenging among Grid resource management because of the heterogeneity in system, network, and sharing of resources with desktop users. Desktop Grids must support thousands to millions of computers with low management overhead. We describe the resource management techniques used in the Entropia Internet and Enterprise desktop Grids, to make the systems manageable, usable, and highly productive. These techniques exploit a wealth of database, Internet, and traditional high performance computing technologies and have demonstrated scale to hundreds of thousands of computers. In particular, the Enterprise system includes extensive support for central management, failure management, and robust execution.
