Abstract

We propose multiple reliability-driven software transformations targeting unreliable hardware. These transformations reduce the executions of critical instructions and spatial/temporal vulnerabilities of different instructions with respect to different processor components. The goal is to lower the application´s susceptibility toward failures. Compared to performance-optimized compilation, our method incurs 60% lower application failures, averaged over various fault injection scenarios and fault rates.
