Ozalp Babaoglu from the University of Bologna presented this Google Talk. “At exascale, failures and errors will be frequent, with many instances occurring daily. This fact places resilience squarely as another major roadblock to sustainability. In this talk, I will argue that large computer systems, including exascale HPC systems, will ultimately be operated based on predictive computational models obtained through data-science tools, and at that point, the intervention of humans will be limited to setting high-level goals and policies rather than performing “nuts-and-bolts” operations.”
