GriddLeS

Grid computing is emerging as a major new capability for modern, high performance technical computing. Such Grids couple geographically distributed resources such as high performance computers, workstations, clusters, and scientific instruments. Traditional methods of producing software for Grids are inefficient and error prone, and will not allow the rapid deployment of new applications.

Much of the effort in Grid computing is being directed towards the construction of new applications, in many cases written from scratch. We are interested in building new applications, but from legacy components. In particular, we want to leverage the billions of lines of code embodied in existing scientific and engineering codes, by stitching them together into new Grid aware applications.

GriddLeS provides an environment that facilitates the composition of arbitrary grid applications from legacy software. The underlying belief is that is possible to take existing programs and grid enable them by providing a high level tool that facilitates the composition of complex systems from smaller, working components.

At the IEEE Supercomputing (SC2003) in Phoenix, Arizona, we demonstrated GriddLeS at the Hewlett Packard booth. Hewlett Packard are industry partners on this ARC funded project.

In this demonstration we will show GriddLeS being applied to some interesting workflows in atmospheric science and astronomy.
