Abstract | Desktopgrids as opposed to service grids are the cost-effective way to gather large amount of volunteer computing resources for solving scientific problems. It is possible to create desktopgrids with the help of only one single machine, where volunteer desktops will connect to process work. MTA SZTAKI has created the hierarchicaldesktopgrid concept, where not only single computers, but also desktopgrids may join other systems increasing their performance significantly. In the paper we investigate scheduling issues of hierarchicaldesktopgrid systems, present schedulingalgorithms focusing on different properties, and compare them using HierDGSim, the HierarchicalDesktopGrid Simulator. |
