A Programming Model and Runtime System for Significance-Aware Energy-Efficient Computing [article]

Vassilis Vassiliadis, Konstantinos Parasyris, Charalambos Chalios, Christos D. Antonopoulos, Spyros Lalis, Nikolaos Bellas, Hans Vandierendonck, Dimitrios S. Nikolopoulos
2014 arXiv   pre-print
However, in many cases, parts of computations can be performed in an approximate way, or even dropped, without affecting the quality of the final output to a significant degree.  ...  The programmer specifies the significance of tasks, and optionally provides approximations for them.  ...  ApproxIt [27] is a framework for approximate iterative methods, based on a lightweight quality control mechanism.  ...

Tuning the Computational Effort: An Adaptive Accuracy-aware Approach Across System Layers

Michael Bromberger
2018
To widen the scope of accuracy-aware computing including approximate computing for other domains, this thesis presents innovative accuracy-aware methods and techniques for different system layers.  ...  The required tuning of the accuracy-aware methods is integrated into a configuration layer that tunes the available knobs of the accuracy-aware methods integrated into a system.  ...  Acknowledgments Doing a PhD is a long way full of ups and downs. It is not successfully viable without the great support of people and thus I want to express my heartfelt thanks to these people.  ...
