Tutorial: System Physician on Chip (SPOC): Dynamic Adaptation for Resilient Integrated Circuits and Systems

Am Freitag, den 01.08.2014 findet um 13:00 Uhr im Raum 3.07.0.08 das Tutorial "System Physician on Chip (SPOC): Dynamic Adaptation for Resilient Integrated Circuits and Systems" von Prof. Krishnendu Chakrabarty (Duke University, USA) statt.

Abstract:

Design-time solutions and guard-bands for resilience are no longer sufficient for nanoscale integrated circuits (ICs). Each chip, due to process variations, is born with a unique personality (“nature”), and because of operating conditions, environment, and workload, grows uniquely (“nurture”). Hence static solutions based on pre-determined adaptation strategies cannot provide adequate resilience as systems evolve with time. While today’s ICs incorporate a large number of sensors (thermal, voltage, delay, etc.) for runtime monitoring, breakthroughs are needed to extract useful information from sensor data, perform real-time analysis, and make decisions about online adaptation. It is important to predict system state so that countermeasures can be taken before a failure occurs.

This talk is focused on data-driven techniques for guiding dynamic adaptation policies. The speaker will first present an aging-aware representative path-selection method that allows us to measure the delay of a small set of paths and infer the delay of a larger pool of paths that are likely to fail due to transistor aging. Moreover, since aging is affected by process variations and runtime variations in temperature and voltage, machine learning and linear algebra are used to incorporate these variations during representative pathselection. Next, to track the effect of workload and usage on circuit operation, the speaker will present a variation-aware path clustering method. The proposed method enables us to measure the delay of a small set of paths and infer the delays of a larger pool of paths that are likely to violatetiming constraints due to parameter variations. Some early results will be presented for benchmark circuits.
