Developing a user-level middleware for out-of-core computation on Grids

Scientists and engineers are faced with more and more out-of-core problems which involve solving large amounts of data. The Grid infrastructure is a large-scale distributed software system that provides a wide and scalable environment for out-of-core computations. This paper constructs a framework of out-of-core computation service on Grids. To provide the users an easy and efficient out-of-core computing interface on computational Grids, a user-level middleware upon the Globus platform is described, which is implemented by adopting the Grid portal technique and the message passing programming model as well as template classes.
