Abstract

This paper reports on results from an ongoing project to develop methods for representing and managing multiple, concurrent levels of modeling detail and enabling high performance computing, namely parallel processing, within object-based simulation frameworks such as HLA. We present here the interface structure and runtime support service concept for using parallel arrays for high performance computing within distributed object-based simulation frameworks. The approach employs a distributed array descriptor, which can be a basis for extending the HLA standard to provide support for efficiently sharing very large data arrays or sub-arrays among federates. The goal is to reduce communications overhead and thereby improve simulation performance involving C4ISR models that require, for example, interpolation and extrapolation of large data sets, such as those that naturally occur for overlay, coupling, and fusion of phenomenology information in multi- sensor networks.
