It may come as a surprise to many who are deeply engaged in exascale research and development that is has already been six years since the first U.S. community town hall meetings were convened to discuss the challenges for the next level of computing. It was in Spring 2007 when meetings were held at Berkeley, Argonne and Oak Ridge that formed the basis for the first comprehensive look at exascale. Even more surprising is that, in spite of numerous national and international activities, the community has not made any significant progress towards reaching the goal of an exaflops system. If one reflects on early projections, it seemed possible to build at least a prototype by 2020. I believe that the lack of progress in the intervening years has made it all but impossible to see a working exaflops system by the end of this decade. Specifically, I don't not expect a working exaflops system to appear in the #1 spot of the TOP500 list with an RMAX performance exceeding 1 exaflop/s by November 2019. In this talk, I will explain why this is a regrettable lack of progress and define the major barriers.
