The MathWorks is working to provide features that will enable users to accelerate computations by taking advantage of GPUs (NVIDIA GPUs in the first release). We are looking for users who can help test these new capabilities and provide feedback.
Did you ever ask yourself how ATI drivers are made, and who makes them? Well, first of all, there are three teams that work on the same driver code at the same time! Why? Continue reading this interesting interview that we had opportunity to conduct with Terry Makedon, Catalyst drivers maker for AMD/ATI graphics cards, and you will found out.
glslDevil is a tool for debugging the OpenGL shader pipeline, supporting GLSL vertex and fragment programs plus the recent geometry shader extension. By transparently instrumenting the host application it allows for debugging GLSL shaders in arbitrary OpenGL programs without the need to recompile or even having the source code of the host program available. The debug data is directly retrieved from the hardware pipeline and can be used for visual debugging and program analysis.

Acropora is a 3D voxel-based procedural mesh synthesizer. Meshes are generated by polygonising iso-surfaces extracted from user-defined density functions. In other words, Acropora expolits voxel modelling to generate complex and interesting meshes.
Definitely try this win32 binary of the Mandelbulb program !!! It's still a prototype, but very cool already.
This program can display a camera flight and smooth morph of a 3D fractal through various powers p=1...10. The program uses the well-known z^p+c iterative formula. The difference to a 2D fractal (e.g. Mandelbrot) is that some extra transformations define the term "z^p" (raise z to the power p) in 3D space. Otherwise it is basically the 2D Mandelbrot formula with arbitrary powers chosen. Power 2 is actually pretty boring in 3D, but higher powers exhibit a lot of fractal patterns. Because of its shape in higher powers it was given the name Mandelbulb.
At PDC, Microsoft talked about what the next version of its browser will bring to the world. IE9 will contain a new emphasis on performance and graphics, and should make the browser far more competitive with its competitors.

- Fixed AUDIODG.EXE consuming large amounts of CPU for some users
Adobe is using DXVA to accelerate Flash video playback, which means you need a GPU that properly supports DXVA2. From NVIDIA that means anything after G80 (sorry, GeForce 8800 GTX, GTS 640/320MB and Ultra owners are out of luck). In other words anything from the GeForce 8 series, 9 series or GeForce GT/GTX series, as well as their mobile equivalents. The only exceptions being those G80 based parts I just mentioned.
Anything based on NVIDIA’s ION chipset is also supported, which will be the foundation of some of our tests today.
AMD supports the following:
- ATI Radeon™ HD 4000, HD 5700 and HD 5800 series graphics
- ATI Mobility Radeon™ HD 4000 series graphics (and higher)
- ATI Radeon™ HD 3000 integrated graphics (and higher)
- ATI FirePro™ V3750, V5700, V7750, V8700 and V8750 graphics accelerators (and later)
It’s a healthy list of supported GPUs from both camps, including integrated graphics. The only other requirement is that you have the latest drivers installed. I used 195.50 from NVIDIA and Catalyst 9.10 from AMD. (Update: The Release Notes now indicate Catalyst 9.11 drivers are required, which would explain our difficulties in testing. ATI just released Catalyst 9.11 but we're having issues getting GPU acceleration to work, waiting on a response from AMD now)
Intel’s G45 should, in theory, work. We tested it on a laptop for this article and since the acceleration is DXVA based, anything that can offload H.264 decode from the CPU using DXVA (like G45) should work just fine. As you’ll see however, our experiences weren’t exactly rosy.
UK-based Allinea is demonstrating an early version of their flagship debugger, DDT, at the show with support for NVIDIA’s CUDA
Following a successful collaboration with NVIDIA and the Commissariat à l’Énergie Atomique (CEA), Allinea Software has developed a version of DDT that offers native support for NVIDIA Tesla GPUs based on the massively parallel CUDA architecture. This Linux-specific version of DDT complements and extends the capabilities of NVIDIA’s CUDA Toolkit by providing the ability to debug HPC applications across clusters of multi-core x86-64 servers, each of which may contain multiple Telsa GPUs. The intuitive GUI interface offers a seamless debugging experience on these hybrid architectures by combining features for MPI, OpenMP and CUDA within a single, easy-to-use development platform.
Early Access Release of the TotalView debugger for the CUDA architecture for NVIDIA GPUs will be available early in 2010
