Summary form only given. Energy/performance results for parallel (and sequential) computing are still, usually hard to predict and often disappointing. A model using invariant-based equations is being applied to predict energy/performance as HW and SW are changed in codesign studies. The physical model consists of HW nodes chosen to match architectural issues, together with automatically extracted SW codelets that are easy to measure and model. HW/SW measurements of computational capacity (BW used) and power [based on HW counters and SW modification (Decan)] are used by the Cape tool to evaluate tradeoffs quickly and find optimal solutions to various codesign problems. Codelets from a number of real applications are being analyzed and modeled.
