Execution of typical scientific applications on Globus-based grids

Abstract

One of the barriers that prevents the expansion and adoption of grid technologies is the lack of a standard programming paradigm to port existing applications among different environments. The distributed resource management application API (DRMAA) has been proposed to aid the rapid development and distribution of these applications across the grid. In this paper we present the first implementation of the DRMAA standard on a Globus-based testbed, and show its suitability to express typical scientific applications. As a case of study, we will consider in this paper the implementation of the NAS grid benchmarks with DRMAA. The DRMAA routines are supported by the functionality offered by the GridWay framework, that provides the runtime mechanisms needed for transparently executing jobs on a dynamic grid environment.
