 +====== Runnemede: An Architecture for Ubiquitous High-Performance Computing ======
 +==== Nicholas P. Carter (Intel) ====

 +===== Abstract =====
 +
 +Runnemede is a research architecture developed as part of DARPA'​s
 +Ubiquitous High-Performance Computing (UHPC) program that was designed to
 +explore the upper limits of energy efficiency without the constraints
 +imposed by backward compatibility and the need to support conventional
 +programming models. ​ It was developed through a co-design process
 +that considered the hardware, the runtime/OS, and applications
 +simultaneously. Near-threshold voltage operation, fine-grained power
 +and clock management, and separate execution units for runtime and
 +application code are used to reduce energy consumption. Memory
 +energy is minimized through application-managed on-chip memory and
 +direct physical addressing. A hierarchical on-chip network reduces
 +communication energy, and a codelet-based execution model supports
 +extreme parallelism and fine-grained tasks.
 +
 +This talk outlines the Runnemede architecture and illustrates how the
 +architecture,​ runtime, and applications influenced each other. ​ We
 +show how our co-design process reduced energy consumption on a
 +synthetic aperture radar application by 75%, and how our
 +software-managed memory hierarchy reduced memory energy by 50-75% on
 +two benchmarks.

 +Nick Carter is a Research Scientist in Intel Labs' Accelerator
 +Architecture Lab, where he develops runtimes and programming
 +techniques for accelerator-based architectures. ​ From 2010-2012, he
 +was a member of Intel'​s Ubiquitous High-Performance Computing project,
 +working on memory systems for energy-efficient architectures. ​ Prior
 +to joining Intel in 2007, Nick was an Assistant Professor at the
 +University of Illinois at Urbana-Champaign. ​ He received his B.S.,
 +M.S., and Ph.D. degrees from M.I.T.
