About the Event
Recently, the combination of semiconductor manufacturing technology scaling and pressure to reduce semiconductor system costs and power consumption has resulted in the development of computer systems responsible for executing a mix of safety-critical and non-critical tasks. However, such systems are poorly utilized if lockstep execution forces all processor cores to execute the same task even when not executing safety-critical tasks. Execution fingerprinting has emerged as an alternative to n-modular redundancy for verifying redundant execution without requiring that all cores execute the same task or even execute redundant tasks concurrently. Fingerprinting takes a bit stream characterizing the execution of a task and compresses it into a single, fixed-width word or fingerprint.
Brett H. Meyer is a Chwang-Seto Faculty Scholar and assistant professor in the Department of Electrical and Computer Engineering at McGill University. He received his MS and PhD in Electrical and Computer Engineering from Carnegie Mellon University in 2005 and 2009, respectively. He received his BS in Electrical Engineering, Computer Science and Math from the University of Wisconsin-Madison in 2003. After receiving his PhD, Meyer worked as a post-doctoral research associate in the Computer Science Department at the University of Virginia. He has been on the faculty at McGill since 2011. Meyer’s research interests are focused on the design and architecture of resilient multiprocessor computer systems.
