General-Purpose Computation Using Graphics Hardware
|
IntroductionGPGPU stands for General-Purpose computation on GPUs. With the increasing programmability of commodity graphics processing units (GPUs), these chips are capable of performing more than the specific graphics computations for which they were designed. They are now capable coprocessors, and their high speed makes them useful for a variety of applications. The goal of this page is to catalog the current and historical use of GPUs for general-purpose computation.

GPGPU.org Launches New Developer Page We are proud to announce an entirely new developer page here at GPGPU.org. On this page you will find a growing number of programming and GPGPU development resources. Content on the page will include tutorials, sample code, utilities, and more. Check back often for updates! In addition, most source code resources posted on the developer page will be made available as open source software hosted at our new SourceForge site, gpgpu.sourceforge.net. There you will be able to download the latest releases, and check out code from the CVS repository.
Posted: 05 May 2004 [GPGPU /Site News] # ShaderTech.com is a new site that's focused on real-time shader development, providing numerous resources such as articles, forums, books, tools, and more. Because there are now several very capable high-level shading languages in active use by developers, ShaderTech aims to support the entire GPU development community regardless of shader language.
Posted: 05 May 2004 [GPGPU /High-Level Languages] # NVIDIA Announces GeForce 6800 GPU NVIDIA Corporation recently introduced its new GeForce 6800 GPU (codename NV40). Among the new features of this GPU are 64-bit floating point texture filtering and blending and support for the D3D vertex and pixel shader 3.0 standard, enabling full dynamic branching and looping in programmable shaders. The GeForce 6800 features 16 pixel pipelines. The improved pixel shader performance of the GeForce 6800 architecture should provide excellent performance for GPGPU applications. NVIDIA report that they have seen over a 3x speedup on a GPU-based Navier-Stokes fluid flow simulation (compared to an NVIDIA GeForce FX 5950).
Posted: 05 May 2004 [GPGPU /GPUs] # ATI Announces Radeon X800 GPUs ATI Technologies recently introduced its new RADEON X800 line of graphics cards (codename R420). Among the new features of these cards are 3Dc, a new compression scheme for normal maps, and support for the D3D ps_2_b pixel shader specification. The ps_2_b shader model allows for pixel shaders up to 512 instructions long with 32 temporary registers. The RADEON X800 XT Platinum Edition features 16 pixel pipelines while the RADEON X800 PRO has 12 pixel pipelines. The improved pixel shader performance of the RADEON X800 architecture should provide excellent performance for GPGPU applications. ATI report they have seen up to a 2.5x speedup on an implementation of GPU-based fluid flow simulation (compared to an ATI RADEON 9800 XT).
