Compiling for Resilience: the Performance Gap

摘要

In order to perform reliable computations on unreliable hardware, software-based protection mechanisms have been proposed. In this paper we present a compiler infrastructure for software-based code hardening based on encoding. We analyze the trade-off between performance and fault coverage. We look at different code generation strategies that improve the performance of hardened programs by up to 2x while incurring little fault coverage degradation.
