This article introduces a significance-centric programming model and runtime support that sets the supply voltage in a multicore CPU to sub-nominal values to reduce the energy footprint and provide mechanisms to control output quality. The developers specify the significance of application tasks respecting their contribution to the output quality and ...

Several applications may trade-off output quality for energy efficiency by computing only an approximation of their output. Current approaches to software-based approximate computing often require the programmer to specify parts of the code or data structures that can be approximated. A largely unaddressed challenge is how to automate the analysis ...

Approximate execution is a viable technique for energy-constrained environments, provided that applications have the mechanisms to produce outputs of the highest possible quality within the given energy budget. We introduce a framework for energy-constrained execution with controlled and graceful quality loss. A simple programming model allows users to express the ...

Full text available: PDFPDF
We introduce a task-based programming model and runtime system that exploit the observation that not all parts of a program are equally significant for the accuracy of the end-result, in order to trade off the quality of program outputs for increased energy-efficiency. This is done in a structured and flexible ...

June 2014 DSN '14: Proceedings of the 2014 44th Annual IEEE/IFIP International Conference on Dependable Systems and Networks
Publisher: IEEE Computer Society
Citation Count: 4

Dependable computing on unreliable substrates is the next challenge the computing community needs to overcome due to both manufacturing limitations in low geometries and the necessity to aggressively minimize power consumption. System designers often need to analyze the way hardware faults manifest as errors at the architectural level and how ...
Keywords: fault-injection, simulation, cycle accurate, full system
