RESUMO

In the collaborative environment of the Computational Grids, there are few tools used for process management and user guide services. This work presents the Grid Process Orchestration (GPO), an infrastructure for service and process orchestration in computational grids, which allows to create and manage complex workflows composed of strongcoupled jobs with no additional support. The GPO is based on the Open Grid Services Architecture (OGSA) and describes workflows using Web Services orchestration concepts applied to computational grid services. This work describes the architecture of the proposed infrastructure, detailing its main components, functionalities for flow management, and shows an implemented prototype. In addition to the architecture, it proposes a compact language for describing workflows. An application example is presented to illustrate the facilities of the proposed infrastructure.
