User – Transparent Run – Time Performance Optimization Miss

Abstract –– High–performance embedded systems– High–performance embedded systems are being implemented as parallel and distributed systems with increasing frequency. There is strong motivation to make such systems adaptive and/or dynamic in order to obtain maximum performance and maximum reliability. One important component of an adaptive or dynamic parallel system is the ability to monitor the performance of running programs and make some effort to optimize execution. The goal of this research, part of a project named Hector, is to monitor the performance of parallel programs ‘‘behind the user’s back’’ to try to minimize run time on available resources.
