09:00-10:00 Keynote
Dimitrios S. Nikolopoulos:
Using Computational Significance and Resilience in System Software Stacks

This talk explores how the runtime system and operating system can leverage metrics that express the singificance and resilience of application components in order to reduce the energy footprint of parallel applications. We will explore in particular how software can tolerate and indeed exploit higher error rates in future processors and memory technologies that may operate outside their safe margins.
