Grid computing systems offer resources to solve large-scale computational problems and are thus widely used in a large variety of domains, including computational sciences, energy management, and defense. Accountability in these application domains is an important requirement, in that it enables controlling activities of users and resource providers through the collection and analysis of accountability data. However, because it is not feasible to simply collect all the potentially useful data, we propose an accountability policy language to simplify administration tasks. In this paper, we show the efficiency of a system that we have developed to implement the language. We first present a short overview of the system, and then assess the proposed accountability policies based on the experiments.
