Abstract

Although several grid projects have the aim to develop portals that hide the complexity of distributed computing infrastructures, only few of these portals support workflow-based applications. The number of portals that enable collaborative workflow development or collaborative resource access is even lower. The paper introduces a model to categorize workflow-oriented grid portals based on two general features: ability to access multiple grids simultaneously and support for collaborative problem solving. The generic features of the different categories are discussed and the Globus-based implementations of the various categories are demonstrated by the P-GRADE Portal.
