A service-based approach for the execution of scientific workflows in grids
Andrea Bosin, Nicoletta Dessì, Madusudhanan Bairappan · 2010
Scientific workflows may be deployed on heterogeneous distributed environments, including Grid resources whose access is not straightforward when it is non compliant with the specific Grid middleware. This paper addresses this complexity and investigates the feasibility of a service oriented approach that takes advantage of the standardized resource access provided by BPEL. The paper proposes specialized Web services, namely BPEL partners, that support the discovering of suitable resources, monitor the execution of each single workflow task in the resource and aggregate results of the execution. Some implementation hints are presented.
