This paper describes a parallel implementation of a grand challenge problem: global atmospheric modeling. The novel contributions of our work include: (1) a detailed investigation of opportunities for parallelism in atmospheric transport based on spectral solution methods, (2) the experimental evaluation of overheads arising from load imbalances and data(More)
In the research described here, we have constructed at tightly coupled set of methods for monitoring, steering, and applying visual analysis to large scale simulations. This work shows how a collaborative, interdisciplinary process that teams application and computer scientists can result in a powerful integrated approach. The integrated design allows great(More)
Diicult computations can be made more eeective and eecient if users can easily contribute to the problems these computations address. This article's purpose is an introduction to the potential increases in functionality and performance gained by the online interaction of end users with high performance computational instruments on single and on networked(More)
