Many people believe that the current levels of U.S. investment and commitment to exascale research fall far short of what is necessary to get the country to exascale-class systems by the end of this decade.
Yet, thousands of very smart HPC community participants have accepted the position, reinforced by hundreds of presentations, that the nation will achieve exascale by 2018.
While other countries look at unified approaches to this daunting technology journey, the U.S. appears to be in jeopardy of losing momentum without a solid, coordinated plan to bring the necessary resources together in support of a national exascale initiative.
