dc.description.abstractPerformance and Power prediction is an active area of research due to its applications in the advancements of hardware-software co-development. Several empirical machine-learning models such as linear models, tree-based models, neural network etc are used for evaluating the performance of machine learning models. Furthermore, the prediction model’s accuracy may differ depending on performance data collected for different software types (compute-bound, memorybound) and different hardware (simulation-based or physical systems).Our results for performance prediction show that the tree-based machine-learning models outperform all other models with median absolute percentage error (MedAPE) of less than 5% consisting of bagging and boosting models that help to improve weak learners. We have also observed that in physical systems, the prediction accuracy of memory-bound applications is higher as compared to compute-bound algorithms due to manufacturer variability in processors. Moreover, the prediction accuracy is higher on simulation-based hardware due to its deterministic nature as compared to physical systems. We have used transfer learning for solving two problems cross-platform prediction and cross-systems prediction. Our result shows the prediction error of 15% in case of cross-systems prediction whereas in case of the cross-platform prediction error of 17% for simulationbased X86 to ARM system using best performing tree-based machine-learning model. For the prediction of the power consumption along with that of performance we have employed several machines learning univariate or multivariate models in our experiments. Our result shows that runtime and power prediction accuracy of more than 80% and 90% respectively is achieved for multivariate deep neural network model in cross-platform prediction. Similarly, for cross-system prediction runtime accuracy of 90% and power accuracy of 75% is achieved for the multivariate deep neural network.
