Abstract

The increasing complexity of High Performance Computing (HPC) applications, especially scientific simulations, has led to the development of the meta-computation model of scientific applications. In this model, an application is constructed from a collection of independent software components potentially written in different programming languages and targeted for different machine architectures. A software interconnection system is then used to connect these heterogeneous components spanning the Internet into a single logical program, and to provide configuration and control capabilities over the resulting computation. This paper describes the meta-computation model, the current state of an interconnection system called Schooner that provides the software infrastructure needed to realize this model, and the use of the model in an on-going NASA jet engine simulation and monitoring project.
