Talk Title: “Achieving Sustainable Computing Through Energy- and Reliability-Aware System Design”

Abstract: Electronic system design has benefited from decades of reliable and predictable functionality, but this trend may likely slow down in future technology nodes. Higher power densities and increased thermal requirements have become first class design constraints, while manufacturing process-driven variability increases, therefore affecting overall performance and power costs. Furthermore, emerging devices are affected by decreased reliability which, in turn, may be exacerbated by higher operating temperatures. To support a path toward sustainable computing, a holistic approach toward addressing energy awareness, reliability, and variability at all the levels in the system is required.

This talk will discuss our work on modeling the effects of process variation at system level and compare and contrast various design styles with respect to their tolerance to process variations and support for increased performance under iso-power conditions. Our results detail how these effects can affect performance, power and thermal profile of systems implemented using classic 2D or advanced 3D integration, how process variations affect the robustness of power management algorithms, and how resource management can be employed to deliver performance increase in multi-core systems. Finally, we unravel the joint effects of decreased reliability and increased variability on system robustness and find unexpected applications of the proposed methodology to non-silicon systems.
