Keynote address thursday: Efficient resilience in future systems: Design and modeling challenges

The cost of maintaining current levels of hardware reliability appears to be un-affordable in the post-22 nm late CMOS design era. In the first part of this talk, we will examine the reasons behind such a projection, based on the modeled trends in technology, circuits and microarchitecture. Then, in the second part, we will present a vision of cross-layer resilience optimization, which forms the basis of an IBM-led project sponsored by DARPA under its PERFECT program. The goal is to demonstrate through parameterized, cross-layer modeling that such an approach can help provide cost- and energy-efficient resilience in a class of future embedded systems of interest to DARPA, U.S. Department of Defense and also to the general IT appliance industry. The modeling framework is targeted to be flexible enough that customized trade-off analyses are expected to be of value to other R&D efforts geared toward high-end server, mainframe, cloud and large-scale supercomputing market segments as well.
