3D-Tech News Around The Web / AMD Introduction to Aparapi video
« on: November 21, 2010, 09:29:15 AM »
The AMD Runtimes team discusses the recently released Java-to-OpenCL™ API, Aparapi, and how it can help Java developers parallelize code without necessarily having to learn a new programming language. Aparapi is a Java API for arranging data parallel solutions to be executed on the GPU, which can convert Java to OpenCL on the fly.

This video discusses the features and applications of Aparapi, as well a preview of what’s to come in the next release. (10:25)

3D-Tech News Around The Web / CUDA, Supercomputing for the Masses: Part 21
« on: November 20, 2010, 08:54:13 AM »
The Fermi architecture and CUDA

In CUDA, Supercomputing for the Masses Part 20, I focused on the analysis capability of Parallel Nsight v1.0 coupled with the NVIDIA Tools extension (NVTX) library to illustrate asynchronous I/O, hybrid CPU/GPU computing, and the performance of primitive restart to dramatically accelerate OpenGL rendering in CUDA applications. (Note that Parallel Nsight 1.5 has been released, which is now compatible with Visual Studio 2010 and further refines the Parallel Nsight experience.)

This article will focus on Fermi and the architectural changes that significantly broaden the types of applications that map well to GPGPU computing while maintaining the performance benefits provided by previous generations of CUDA-enabled GPUs. Particular attention will be paid to how the Fermi architecture affects CUDA memory spaces. Also discussed will be how the Fermi architecture moves GPU computing into mainstream 24/7 production computing with error correction and other robustness features.

3D-Tech News Around The Web / Paint.NET v3.5.6 released
« on: November 20, 2010, 08:52:48 AM »
Paint.NET v3.5.6 - Download, released on November 18th, 2010
This update fixes several issues related to copy-paste, improves performance and quality for a few adjustments, and fixes a data loss bug.

    * When pasting an image, Paint.NET will be smarter about ensuring it is placed within the area that has been scrolled/zoomed to.
    * Improved the performance and quality of the Curves and Hue/Saturation adjustments.
    * Some minor improvements to memory usage, which should help out a few scenarios on 32-bit systems.
    * Fixed: If a JPEG was loaded that had an embedded ICC profile, and was then saved as an 8-bit or 24-bit PNG, then the resulting file would be corrupt (32-bit PNG worked fine though).
    * Fixed: 16-bit TGAs no longer load with the red and blue channels swapped.
    * Fixed: Copy-paste from a Remote Desktop session will no longer be 'shifted' by 3 pixels.
    * Fixed: Copy-paste from Internet Explorer, Firefox, or Chrome should preserve alpha/transparency.
    * Fixed: Copying from Paint.NET and pasting into Windows Live Writer should now work.
    * Fixed: Taking a full-screen screenshot with Print Screen on a multimonitor system, where those monitors don't form a simple rectangle, will now fill the 'gap area' with transparent instead of black. (Example: two monitors of the same size, one of which is rotated by 90 degrees)
    * Fixed: If Paint.NET is opened without specifying an image to open, and then the default image is modified and saved, then Paint.NET will no longer close it upon opening another one. This was causing data loss if that default image had layers, and was then saved in a format that did not support layers (anything other than .PDN).
    * Fixed: Some systems were showing 'red X' thumbnails for .PDN files in Windows Explorer, instead of the real thumbnail.
    * Fixed: The EXIF "Creation Software" saved along with images is no longer localized. This prevents certain languages from seeing "Paint.NET ????? v3.5.6" in the image properties (metadata).

3D-Tech News Around The Web / Fluid Simulation for Video Games (Part 8)
« on: November 18, 2010, 05:19:28 PM »
This article, the eighth in a series, explains how a vortex-based fluid simulation handles variable density in a fluid.
This article introduces features to the simulations presented in previous articles: The fluid flow includes motion because of buoyancy-heavier fluid sinks, and lighter fluid rises. These new features facilitate visual effects with effects of variable density or (with additional rendering work) multiple fluids, such liquid-gas mixtures like water and air. It also lays the groundwork for upcoming features like thermal convection (hot air rises) and combustion (generating heat from chemical processes).
