Talk Title: Checkpointing`a la Young/Daly

Abstract:  The Young/Daly formula provides an approximation of the optimal checkpoint period for a parallel application executing on a large-scale platform. It was originally designed to handle fail-stop errors for preemptible tightly-coupled applications. It has recently been extended to other application and resilience frameworks, such as workflows, silent errors, and imprecise knowledge of key parameters (MTBF and checkpoint duration). We provide some background and survey various scenarios to assess the usefulness and limitations of the formula.

Bio: Yves Robert is a Full Professor at ENS Lyon, a Fellow of the IEEE and a former Senior Member of Institut Universitaire de France.  He received the 2014 IEEE TCSC Award for Excellence in Scalable Computing, the 2016 IEEE TCPP Outstanding Service Award, and the 2020 IEEE CS Charles Babbage Award. He holds a Visiting Scientist position at the Innovative Computing Laboratory, University of Tennessee Knoxville, since 2011. His main research interests are scheduling techniques, parallel algorithms and resilient approaches for large-scale platforms.
