Abstract: Grid interoperability has recently become a major issue at Grid forums. Most of the current ideas try to solve the problem at the middleware level where unfortunately too many components (information system, broker, etc.) should be made interoperable. As an alternative concept the P-GRADE/GEMLCA portal is the first Grid portal that targets the problem at the level of workflows. Different components of a workflow can be executed simultaneously in several Grids providing access to a larger set of resources. More than that, the workflow level completely hides the low level Grid details for the end-user who does not have to learn low level Grid commands of different Grids. The paper describes how the P-GRADE Portal and GEMLCA enable the execution of workflows in multiple Grids based on different 2nd (GT2 and LCG-2) and 3rd (GT4 and g-Lite) generation Grid middleware.
