Elastic Fidelity: Trading-off Computational Accuracy for Energy Reduction
نویسندگان
چکیده
§ Elastic Fidelity: exploit the inherent error-tolerance of applications to lower the energy consumption, and withstand the massive errors of future computing. § Allow some data to be imprecise § Programming language constructs and ISA extensions pass the fidelity requirements from application to hardware § Hardware models adjust the voltage to maintain fidelity guarantees § The execution system steers imprecise computations to components with low voltage § Error-tolerant data are stored at low-voltage storage

The Fidelity Slider: a User-Defined Method to Trade off Accuracy for Performance in Canny Edge Detector
This paper presents the concept of a fidelity slider, which is a user-defined method that enables trading off accuracy for performance in a parallelized application. The slider is defined in the context of the Canny edge detector, but can be generalized to other image processing algorithms. The slider moderates discontinuity issues introduced by an image-slicing technique used to increase the l...
متن کاملEfficiency of Anti-Hourglassing Approaches in Finite Element Method (TECHNICAL NOTE)
one of the simplest numerical integration method which provides a large saving in computational efforts, is the well known one-point Gauss quadrature which is widely used for 4 nodes quadrilateral elements. On the other hand, the biggest disadvantage to one-point integration is the need to control the zero energy modes, called hourglassing modes, which arise. The efficiency of four different an...
متن کاملTrading-Off Cost of Deployment Versus Accuracy in Learning Predictive Models
Predictive models are finding an increasing number of applications in many industries. As a result, a practical means for trading-off the cost of deploying a model versus its effectiveness is needed. Our work is motivated by risk prediction problems in healthcare. Cost-structures in domains such as healthcare are quite complex, posing a significant challenge to existing approaches. We propose a...
