  3. Abstract:
  4. Escalating reliability threats and performance issues due to process variations under the tight power envelopes of multi- /many-core chips challenge the cost-effective deployment of future technology nodes. We propose an adaptive run-time system that synergistically integrates heterogeneous hardening modes at both hardware and software levels, and selects appropriate hardening modes for concurrently executing applications under total chip power budget and timing constraints, while optimizing for reliability. To enable a high level of adaptability, we perform a comprehensive analysis of various design tradeoffs and study the impact of hardware/software hardening modes in terms of achieved reliability, power consumption, and performance.
