P-GRADE Portal: A generic workflow system to support user communities

P-GRADE portal is an open-source multi-grid portal that supports creation, execution and management of traditional and parameter study workflows on gLite and GT-2 infrastructures. However, some user communities need support for other grid types, like desktop grids or the Amazon EC2 cloud, as well. In this paper we will present the internal architecture of P-GRADE Portal as well as the implementation details of grid support methods. This paper intends to give support for those communities who would like to further develop the portal or create a similar one for other workflow systems.

Research highlights
► Description of architectural details of a generic grid portal.
► Parameter study workflow execution support description based on the preparation, execution, and post-processing phases.
► The use of different grid middlewares within a generic grid portal.
