Waldburger, M., Göhner, M., Reiser, H., Dreo Rodosek, G., Stiller, B. (2008):Evaluation of an Accounting Model for Dynamic Virtual OrganizationsAccounting of Grid resource and service usage determines the central support activity for Grid systems to be adopted as a means for service-oriented computing in Dynamic Virtual Organizations (DVO). An all-embracing study of existing Grid accounting systems has revealed that these approaches focus primarily on technical precision, while they lack a foundation of appropriate economic accounting principles and the support for multi-provider scenarios or virtualization concepts. Consequently, a new, flexible, resource-based accounting model for DVOs was developed, combining technical and economic accounting by means of Activity-based Costing (ABC). Driven by a functional evaluation, this paper pursues a full-fledged evaluation of the new, generically applicable Grid accounting model. This is done for the specific environment of the Leibniz Supercomputing Centre (LRZ) in Garching, Germany. Thus, a detailed evaluation methodology and evaluation environment is outlined, leading to ology and evaluation environment is outlined, leading to considered Grid services. The results gained are analyzed and respective conclusions on model applicability, optimizations, and further extensions are drawn.
