Providing Quality of Science in Volunteer Computing

We propose an application-centric approach for tuning, at runtime, parameters in volunteer computing (VC). Our approach defines Quality of Science (QSc) as the ability of a system to meet application-specific goals within time constraints. We first estimate the impact of different application parameters on both QSc metrics and resource usage from empirical information gathered at runtime and then reconfigure the parameters accordingly. Our approach results in more accurate solutions in shorter times and lower resource consumption than other, more traditional approaches.
