Post-exascale supercomputing for the NNSA (National Nuclear Security Administration) is the subject of a new report by a distinguished review committee comprised of notable supercomputing experts, three of whom presented their findings at a webinar last week. Among other observations Shahin and Doug came away with is that those responsible for guiding U.S. supercomputing leadership on the global stage are under relentless pressure, in an increasingly challenging environment, to make mistake-free, long-term strategic choices. Their task is like that of Sisyphus, except the boulder never rolls down the mountain, it must eternally be pushed up. As one of the panelists — Dan Reed of the University of Idaho — said, “in supercomputing, these are the best of times and the worst of times.”
