Interoperating grid infrastructures with the GridWay metascheduler

This paper describes the GridWay Metascheduler and exposes its latest and future developments, mainly related to interoperability and interoperation. GridWay enables large-scale, reliable and efficient sharing of computing resources over grid middleware. To favor interoperability, it shows a modular architecture based on drivers, which access middleware services for resource discovery and monitoring, job execution and management, and file transfer. This paper presents two new execution drivers for BES and CREAM services, and introduces a remote BES interface for GridWay. This interface allows users to access GridWay’s job metascheduling capabilities, using the BES implementation of GridSAM. Thus, GridWay now provides to end-users more possibilities of interoperability and interoperation. Copyright c ⃝ 2010 John Wiley & Sons, Ltd.
