Astrophysical Supercomputing with GPUs: Critical Decisions for Early Adopters

A paper recently published by the Astronomical Society of Australia on how GPGPUs are dramatically changing the landscape of high performance computing in astronomy.This paper identifies and investigates several key decision areas, with a goal of simplifying the early adoption of GPGPU in astronomy. The merits of OpenCL are considered as an open standard in order to reduce risks associated with coding in a native, vendor-specific programming environment, and present a GPU programming philosophy based on using brute force solutions.

OpenCL: The Future of Accelerated Application Performance Is Now

This white paper is a followup to the AMD FirePro webinar "OpenCL & the Future of Desktop High Performance Computing in CAD" (now on-demand). It is a worthwhile introduction to what OpenCL and general-purpose computing across both CPUs and GPUs. In addition to the technology, it discusses why use an open standards / non-proprietary approach and the rapid growth rate of OpenCL. Finally it describes some of the applications that will take immediate advantage of OpenCL including numerical computation and high-end visualization in CAD/CAM/CAE or real-time visualization/presentation, real-time video processing, and physics simulations in DCC/ Media & Entertainment.
