eNANOS Grid Resource Broker

Abstract. Grid computing has been presented as a way of sharing geographically and organizationally distributed resources and of performing successfully distributed computation. To achieve these goals a software layer is necessary to interact with grid environments. Therefore, not only a middleware and its services are needed, but it is also necessary to offer resource management services to hide the underlying complexity of the Grid resources to Grid users. In this paper, we present the design and implementation of an OGSI-compliant Grid resource broker compatible with both GT2 and GT3. It focuses in resource discovery and management, and dynamic policies management for job scheduling and resource selection. The presented resource broker is designed in an extensible and modular way using standard protocols and schemas to become compatible with new middleware versions. We also present experimental results to demonstrate the resource broker behavior
