A resource accounting and charging system in Condor environment

The authors' aim is to create a resource accounting and charging system for the Grid environment that can be set up as part of the supercomputing Grid prototype, which is developed in an ongoing domestic project. Stiller, Gerke, Reichl and Flury [1,2] has introduced a distributed accounting and charging concept, in which they point out that it could be applied in Grid context as well. This model has been adopted and improved by the authors in the given context; they had created the specification of a proposed solution at algorithm level. The necessary data structures and its query interfaces have been defined. The metering, accounting and pricing processes have been implemented. The system has been adapted to the Condor workload management system. The resulting application has been deployed at the departmental cluster. The authors funnel is to continue developing the remaining modules of the system and bring out the completed version as the part of the professional services for the Grid. This paper introduces the applied model, the specification that was built upon it, the results of the implementation and the operating test environment.
