Extreme Scale Computing Studies

This document is the draft Final Technical Report for Georgia Institute of Technology Georgia Tech, GT Project 210667V, Exascale Computing Study ECS. Four studies were conducted to determine the technical developments needed for a 1,000x increase in computational capability by 2015. 1. The Exascale Computing Study, addressing hardware and system architecture issues 2. The Exascale Computing Software Study, addressing software technologies to effectively utilize extreme levels of concurrency 3. The Exascale Computing Resiliency Study, addressing practical fault management in extreme scale systems and 4. The Embedded Extreme-scale System Study, addressing elements of extreme scale applications and benchmarks, low-power algorithms, design simulation methods, programmability metrics, and enabling tools for graphics processing unit use. The studies identified critical technology challenges in power and energy concurrency resiliency and memory and storage. Investments were recommended in locality and parallelism expression and optimization power management self-awareness techniques execution models extreme scale benchmarks, programmability metrics, low power algorithms, and libraries for graphics processing units.
