Abstract

Parallel scripting is a loosely-coupled programming model in which
applications are composed of highly parallel scripts of program invocations that process and exchange data via files. We characterize here the applications that can benefit from parallel scripting on petascale-class machines, describe the mechanisms that make this feasible on such systems, and present results achieved with parallel
scripts on currently available petascale computers.
