Michel Kinsy, Ph.D.

In this talk I will present a novel Multicore Architecture for Real-Time Hybrid Applications (MARTHA) with time-predictable execution,low computational latency, and high performance that meets the requirements for control, emulation and estimation of next-generation power electronics and smart grid systems. Our approach allows a large class of cyber-physical systems to be expressed as adaptive hybrid models executable on a single hardware platform.I will also introduce Athena, a general-purpose version of MARTHA that dynamically adapts and optimizes its execution behavior according to a set of high-level application goals (e.g., performance to power ratio, hard real-time constraints, reliability and security awareness). Athena represents a new, non-Von Neumann model of computation and provides a framework for future, cognitive, probabilistic, and adaptive computer system architectures. Using various machine learning and control theory techniques, it is able to: reason about the trade-off between the precision of results and the computational time; evaluate whether or not more time will yield better answers; and reason about "goodness" of the current solution or the computational progress in a given application execution stage. Michel Kinsy graduated from the Massachusetts Institute of Technology (MIT) with a Ph.D. in Electrical Engineering and Computer Science in June 2013.
