Performance Modeling and Prediction of Real Application Workload in a Volunteer-based System

Abstract: The goal of this paper is to present a model that predicts the real workload placed on a volunteer based system by an application, with incorporation of not only performance but also availability of volunteers. The application consists of multiple data packets that need to be processed. Knowing the computational workload demand of a single data packet we show how to estimate the application workload in a volunteer based system. Furthermore, we show how real life metrics obtained from the BOINC volunteer system can be applied to the proposed model.
