Abstract

This study focuses on a particular application domain (iterativeautomatic target recognition tasks) and an associated specific class ofdedicated heterogeneous parallel hardware platforms. For thecomputational environment considered, a methodology is presented forthe on-line operating system to decide heuristically whether to performa remapping of the application onto the platform based on informationgenerated from input data by the application during execution. If thedecision is to remap, the operating system will be able to select amapping, which is appropriate for the given state of the application,from a stored set of mappings that were previously derived with anoff-line heuristic.
