This talk will use Montage (http://montage.ipac.caltech.edu/), an astronomical image mosaicking application that is a toolbox of independent components, to explore various application paradigms on parallel and distributed systems, as the Montage components can be used in a variety of settings, including on a single system, on a parallel system, or on a set of distributed systems, including grids and clouds. Montage, which was built to use MPI in parallel, and Pegasus/DAGman on distributed systems, has also been used as an exemplar many-task computing (or workflow) application by a number of other tool and system developers. In this talk, a variety of work with Montage will be discussed, including the use of multiple types of infrastructure/middleware, the use of scripting to allow a user to easily customize their use of the Montage components, and overcoming data management issues.
