Towards a volunteer cloud system

The paper completes the work started in the EU FP7 EDGI project for extending service grids with volunteer (global) and institutional (local) desktop grids. The Generic BOINC Application Client (GBAC) concept described in the paper enables the transparent and automatic forwarding of parameter sweep application (parametric) jobs from service grid VOs (Virtual Organizations) into connected desktop grids without any porting effort. GBAC that introduces virtualization for the volunteer BOINC (Berkeley Open Infrastructure for Network Computing) clients can also be considered as a first step towards establishing volunteer cloud systems since it provides solutions for several problems of creating such a volunteer cloud system
