Abstract: The expansion and adoption of Grid technologies is prevented by the
lack of a standard programming paradigm to port existing applications among
different environments. The Distributed Resource Management Application API has
been proposed to aid the rapid development and distribution of these
applications across different Distributed Resource Management Systems. In this
paper we describe an implementation of the DRMAA standard on a Globus-based
testbed, and show its suitability to express typical scientific applications,
like High-Throughput and Master-Worker applications. The DRMAA routines are
supported by the functionality offered by the
GridWay^{2}framework, which provides the runtime mechanisms
needed for transparently executing jobs on a dynamic Grid environment based on
Globus. As cases of study, we consider the implementation with DRMAA of a
bioinformatics application, a genetic algorithm and the NAS Grid
Benchmarks.
