Exascale on what dimension, and why?

SPPEXA Annual Meeting 26 Jan 2016, Leibniz Supercomputing Centre, Munich, Germany.US President Obama recently signed an executive order creating the National Strategic Computing Initiative. This executive order sets out a goal of creating an exaFLOPS computational system for the US. One of the announcements about this initiative quoted the President' s Council of Advisers on Science and Technology which has previously stated that high-performance computing is a must now assume a broader meaning, encompassing not only flops, but also the ability, for example, to efficiently manipulate vast and rapidly increasing quantities of both numerical and non-numerical data. This talk will discuss US efforts toward exascale computation, particularly considering the synergies between developments needed to enable exascale tightly coupled parallel work- loads and exascale big data computations
