3D-Tech News Around The Web / Visions Of Chaos
« on: September 21, 2010, 09:15:30 AM »

Visions Of Chaos is a professional high end software application for Windows. It is simple enough for people who do not understand the mathematics behind it, but advanced enough for fractal enthusiasts to tweak and customise to their needs. It is the most complete all in one application dealing with Chaos Theory available. Every mode is written to give the best possible quality output. There are thousands of sample files included to give you an idea of what Visions Of Chaos is capable of.

Aparapi is an API for expressing data parallel workloads in Java and running those workloads on a compatible GPU if possible. Where your workload actually ends up running depends on

    * whether you have the ATI Stream SDK installed
    * whether you have a compatible GPU
    * whether your Java parallel code avoids any constructs that would make it untranslatable to OpenCL™. These restrictions are detailed in the Aparapi Readme file.

If your code and your target platform meet all of the above, Aparapi will translate your workload to OpenCL™ and will run your workload on the GPU. Otherwise, your same code will still run as a parallel workload using a Java Thread Pool and will be able to take advantage of multiple cpu cores if you have them.

3D-Tech News Around The Web / OpenCL – Portable Parallelism Tutorial

Architecture and balance ratios are key concepts that are essential to understanding OpenCL device performance. In particular, the bandwidth of the link between the host and OpenCL device, along with the memory bandwidth of the device can be key performance metrics. In some cases, either of these hardware characteristics can make it too expensive to move a calculation from the host onto an OpenCL device. However, many problems require enough computation per data item transferred to greatly speed OpenCL applications.
...
Finally, this tutorial has provided a quick and basic introduction to OpenCL along with an example code that can run on both CPU and GPU device types. Try it and see how it works.

Join James Fung from Developer Technology at NVIDIA as he covers the following advanced topics for DirectCompute:

    * Work distribution best practices
    * Compute shader code best practices
    * Algorithm selection best practices
    * Multi-GPU best practices

He also gives an example problem, scan/reduction, and then goes through various optimizations for that problem.

Finally I've got radix sort implementation which is working on AMD OpenCL. ... And now we have new more interesting results 
Time of GPU sorting includes time of data downloading from video memory. Sorted structure is single uint2 array for bitonic sort, and two int arrays for radix sort.

When the FirePro series based on AMD's Evergreen GPU was first hitting the street they had a huge lead in performance and feature set making them the perfect upgrade for professional users looking for the best available product.  Since then NVIDIA has released their Quadro update based on the Fermi architecture and has taken back some of the spotlight; AMD still has the edge in features but the performance edge probably leans towards NVIDIA for now.  That being said, if you are in the market for a multi-display card, there is nothing even close to the FirePro V9800 and its 6 DisplayPort outputs except maybe AMD's own V8800 with four.  AMD is hoping to capitalize on that customer need with a solution that can dramatically lower their costs and provide new development and display experiences.

POWERVR Insider SDK has some nice samples and a GUI with a comprehensive log.
The videos from native demos look still better though.

ARM Mali emulator works fine with either ATI or NVIDIA.
It requires Cygwin, i.e. cygwin1.dll in system path or application folder.

The samples didn't knock my socks off  :P

3D-Tech News Around The Web / Re: [GLES 2.0] Qualcomm Adreno SDK 2.1

Shader samples rechecked, it appears that only a third doesn't like NVIDIA.

From my understanding these samples do not use native GLES2.0, but a wrapper that translates functions into "regular" OpenGL

More GLES2.0 SDKs will be tested later...

Release 3.2 Beta (R260 Beta Driver Update)
[Windows]
* CUDA SDK Visual Studio projects have been revised to use environment variables $(CUDA_PATH) to reference the
  CUDA Toolkit Installation path, includes, and compiler.  The CUDA tookit also installs NvCudaDriverAPI.rules
  and NvCudaRuntimeApi.rules to refer to rules files which are versioned: NvCudaDriverApi.v3.2.rules and
  NvCudaRuntimeApi.v.3.2.rules.  To help with development migration from CUDA 3.1 to CUDA 3.2, the environment
  paths CUDA_BIN_PATH, CUDA_INC_PATH, and CUDA_LIB_PATH are defined and set by the CUDA 3.2 toolkit.

  Please refer to the Getting_Started_Windows.pdf on windows and the CUDA toolkit release notes for
  more details in the CUDA Toolkit release notes.

* Added cudaEncode sample (not pre-built) which demonstrates CUDA GPU accelerated video encoding of YUV to (H.264 and VC-1).
* Added SLI D3D10 Texture sample that demonstrates improved performance for multi-GPU configurations.
* Added Interval Computing sample (illustrates how to use Recursion on Fermi Architecture)
* Added VFlocking (not-pre built) sample demonstrating a CUDA simulation of bird flocking behavior.

[All OS]
* Added MonteCarloCURAND samples for estimation of MonteCarlo Simulation with the NIVIDA CURAND libraries
    EstimatePiInlineP, EstimatePiInlineQ, EstimatePiP, EstimatePiQ, SingleAsianOptionP
* Add bilateralFiltering sample
* Add conjugateGradient solver on the GPU using CUBLAS and CUSPARSE libraries
* Add simplePrintf (shows how to call cuprintf through device code)
* Updated DeviceQuery/DeviceQueryDrv samples to support determine if ECC/TCC is enabled for Tesla devices

* Added FunctionPointers (version of SobelFilter) sample, requires GPU based on Fermi architecture
* Updated BicubicTexture sample to include Catmull Rom

Welcome to QUALCOMM's Adreno™ Software Development Kit (SDK). This is the first commercial of the SDK for OpenGL ES 2.0 Emulator on Windows. This kit is intended to provide developers with the inside scoop on getting the most out of QUALCOMM's latest handheld graphics products.

The robot demo runs on either NVIDIA or ATI GPU.



OpenGL ES 2.0 shader samples #0-14 with teapot model crash nvogl32.dll, #15-49 work with NVIDIA, no issues with ATI



Change value in "Media/CurrentScene.txt"  to match the shader number in folder "Shaders_Raw"

I wonder if these GLSL shaders work in GeexLab?

3D-Tech News Around The Web / AMD Space Command - Direct2D benchmark
« on: September 16, 2010, 04:30:15 PM »
AMD Space Command is a fun game that shows the graphics acceleration of Direct2D technology in the Internet Explorer 9 browser.

 Shoot as many space attackers possible, and use the "GPU capacitor" to adjust the intensity of the game.

AMD Space Command is built in HTML5, a programming language designed to leverage the GPU in your PC to improve the performance of graphics-intensive applications. You can see this first hand by keeping track of the changes in the "Frames Per Second (FPS) indicator as you adjust your GPU capacitor

Overview

This library provides software developers with the ability to query ATI GPU software and hardware state information that is not normally available through standard operating system or graphic APIs. Version 1.0 of the library includes support for querying graphics driver version info, Crossfire (ATI’s multi-GPU rendering technology) configuration info, as well as Eyefinity (ATI’s multi-display rendering technology) configuration info. AGS is available in dynamic and static library form for 32 and 64 bit versions of Microsoft® Windows® XP, Vista, and Windows 7.

What's in the package

    * ATI GPU Services (AGS) Library (static and dynamic linked library for 32 and 64 bits version of Windows XP, Vista and Windows 7).
    * AGS sample, a console mode sample shows you how to query information from AGS library.
    * Eyefinity sample, a sample shows you how to use AGS library to query Eyefinity configuration information for your application. This sample also shows you how to use multiple cameras to render 3d scene with Eyefinity technology.

Download



The samples require developer runtimes from MSVC2008 and DXSDK AUG 2009
