Exascale supercomputer components are increasing in size and complexity, resulting in increased failures; while scalability at the end of Moore era faces decreasing transistor lifetimes and increased variability. Therefore, reliability is becoming a first-class system design criteria in addition to performance and power. Hardware solutions by themselves will not be sufficient to mitigate the future error rates. In this research line, the group will investigate how to "marry" innovative hardware and software ideas for resilience.  Areas of activity include going below safe operating voltages to save energy, leveraging task-based  and use of fault-prediction for proactive fault tolerance.
