GPU Parallel Programming
GPU programming continues to advance in terms of proprietary programming interfaces, generic open programming interfaces, and inclusion in strategic applications. Recent products from Nvidia include the following.
Version 2.3 of the CUDA (Compute Unified Device Architecture) Toolkit and SDK (software development kit) includes performance improvements and expanded support for the CUDA-GDB hardware debugger, says Nvidia. Additional features include the CUFFT (Compute Unified Fast Fourier Transform) Library, which now supports double-precision transforms and includes performance improvements for single-precision transforms. CUDA-GDB and the CUDA Visual Profiler are included in the CUDA Toolkit installer. Additionally, each GPU in an SLI (Scalable Link Interface) group is enumerated individually so that applications can exploit multi-GPU performance even when SLI is enabled for graphics. In addition, the 64-bit versions of the CUDA Toolkit now support compiling 32-bit applications.
The first OpenCL 1.0-conformant drivers for Windows XP and Linux are available to all Nvidia GPU-computing registered developers. The drivers support CUDA-based GPUs and include updates to the OpenCL SDK code samples, a new SDK oclsobelFilter sample, Open CL compiler and driver binaries, OpenCL for compute-capable GPUs documentation, and support for Windows XP 32 and 64 and Linux 32 and 64.
Nvidia's Quadro GPU technology has been optimized for Autodesk AutoCAD 2010. According to Nvidia, Quadro processors let design professionals create and interact with more-complex 3D product designs. They claim that Quadro processors offer the best price performance for workstation graphics and enable up to a five-times performance increase in the 3D-hidden visual style and faster interactive manipulation of models in the conceptual and realistic visual styles. According to Nvidia, Quadro processors offer the ability to manipulate and interact with large-scale models while working at the maximum visual quality necessary to render high-polygon 3D models precisely. The nView display software is flexible for single large displays or multidisplay options at resolutions up to 2,560 × 1,600 per display. The drivers are free and available for download at www.nvidia.com
. They're available as a standalone package or integrated in the latest graphics driver from Nvidia.
