Abstract :
An instruction scheduling technique is presented that targets at improving the reliability of a software program given a user-provided tolerable performance overhead. A look-ahead-based heuristic schedules instructions by evaluating the reliability of dependent instructions while reducing the impact of spatial and temporal vulnerabilities of various processor components. Our reliability-driven instruction scheduler (implemented into the GCC compiler) provides on average a 22% reduction of program failures compared to state-of-the-art.
