| Parallel Coding with GPUs: Should You Wait? |
A look at real GPU options and some issues that still need to be addressed
Jacques du Toit
While the cost of high performance computing (HPC) has been reducing steadily over recent years, it may still put some people off. The advent of general purpose graphical processing units (GPGPU) has both accelerated the cost reduction and improved the energy efficiency of some HPC installations. The experiences of those who have written GPGPU algorithms, and who know HPC systems (some with GPGPU capability), may help you decide whether this technology is right for you. ...continue |

| Modifying Google’s MapReduce to Increase GPU Cluster Computing |
Adding three new steps allows GPU and MapReduce to work together
Mike Martin
A modified version of MapReduce — Google’s patented program for distributed and cluster computing — harnesses the power of graphics processing units (GPU) for large-scale, high-performance applications, claim University of California, Davis computer science researchers. In benchmark performance tests, GPMapReduce increased both speed and efficiency on a GPU cluster, explained UC Davis graduate student Jeff Stuart, who with electrical and computer engineering professor John Owens developed the new approach. ...continue |

| Maximizing MultiGPU Machines |
Multiple GPU and hybrid CPU+GPU performance is heavily dependent upon vendor implementation of the PCIe bus
Rob Farber
GPU technology provides orders of magnitude speedups with a single GPU over a conventional processor. Plugging two or four GPUs into a workstation or computational node can double or quadruple the performance of computational applications and games. Even more performance can be achieved by utilizing the multicore capability of the host processor in concert with the GPUs in a system. ...continue |

General-purpose computing on graphics processing units — a brief history
William L. Weaver, Ph.D.
In the mid-1970s, filmmaker George Lucas sought to capture his vision for a space opera called The Star Wars on motion picture film. The difficulty was that the technology did not yet exist to create the vast special effect sequences that were required to tell an ancient story set in a galaxy far, far away. To solve this problem, Lucas acquired space in a vacant warehouse located next to the Van Nuys Airport near Los Angeles, CA and assembled an interdisciplinary team of special effects artists, model makers and engineers that later became known as Industrial Light and Magic (ILM). ...continue |

| HPC Market Showdown: GPU Momentum Growing |
While still generally experimental, GPUs have tripled their worldwide footprint in the past two years
Steve Conway
What a difference two years can make in the fast-paced world of HPC technology adoption — a market considerably less risk-averse than its mainstream IT counterpart. IDC’s 2008 worldwide study on HPC processors revealed that nine percent of HPC sites were using some form of accelerator technology in their installed systems. GPGPUs (henceforth to be called GPUs) shared the accelerator habitat back then with FPGAs, Cell processors and a few rarer species. ...continue |
