Using a "codelet" program execution model for exascale machines

Abstract

As computing has moved relentlessly through giga-, tera-, and peta-scale systems, exa-scale (a million trillion operations/sec.) computing is currently under active research. DARPA has recently sponsored the "UHPC" [1] --- ubiquitous high-performance computing --- program, encouraging partnership with academia and industry to explore such systems. Among the requirements are the development of novel techniques in "self-awareness"in support of performance, energy-efficiency, and resiliency.
