TOWARDS A GRID SERVICES BASED FRAMEWORK FOR THE VIRTUALIZATION, EXECUTION AND COMPOSITION OF MPI APPLICATIONS

Abstract

We present Quantify, a programming framework for exposing high-performance parallel MPI applications using Grid Services. The two distinctive programming styles of Grid Services and MPI are bridged using a data-centric virtualization approach through the notion of Uses and Provides Quantities. Quantities are used to describe an abstract application interface, permit data exchange between applications and facilitate the composition of two or more applications in a service workflow. Uses and Provides Quantities are modelled using Service Data Elements (SDEs). Finally we demonstrate the applicability of the framework using a Flood Crisis application scenario.
