REAL-TIME PERFORMANCE MONITORING, ADAPTIVE CONTROL, AND INTERACTIVE STEERING OF COMPUTATIONAL GRIDS

摘要

To support creation of nimble applications for computa- tional grids, the authors believe one must eliminate the barrier that separates program creation from execution and post-mortem optimization. This paper outlines an ap- proach to dynamic performance adaptation and distrib- uted optimization in the grid environment based on a suite of performance instrumentation, analysis, and presenta- tion tools that includes distributed performance sensors and resource policy actuators, fuzzy logic rule bases for adaptive control, and immersive visualization systems for real-time visualization and direct manipulation of software behavior.
