Khronos Group expands OpenCL forums for coders

The Khronos Group has expanded the OpenCL section of their public forums, giving an area for users and coders to mingle together. The forums now contain categories for beginner and advanced coders, hardware and software issues for end users, OS specific question and help, and an area to discuss SDK's, toolkits and wrappers. The Khronos Group message boards are visited by the developers behind all the Khronos API's on a regular basis, and offer the best place to get help and give help. We look forward to seeing you on the Khronos forums soon. Read More

WebGL appears in Mozilla trunk

Michael Smith posted on his twitter page this morning that WebGL has appeared in the Mozilla trunk. It was just three days ago that WebGL was first noticed in WebKit. From the homepage of Michael Smith, "I joined the W3C in 2007 as part [of] the W3C Mobile Web Initiative. I am involved with the work on The HTML Markup Language and on standards related to browsing technologies; in particular, the phenomenon known as HTML5, as well as other standards related to Web Applications."

Grand Central Dispatch and Open CL Bring Significant Performance Improvements

MovieGate developer Christophe Ducommun has been optimizing his application for the new Snow Leopard operating system with Grand Central Dispatch and OpenCL. His results show approximately 50% increase in video encoding speed when compared to the plain Leopard, while also reducing the CPU load during video decoding by passing some of the work to the graphics processing unit. These results highlight the potential performance gains OpenCL and Grand Central Dispatch can bring as developers begin to take advantage of them. Read More

Pixelux and AMD to develop OpenCL acceleration for Digital Molecular Matter engine

Pixelux will work with AMD to develop an OpenCL accelerated Digital Molecular Matter engine. Pixelux are the folks who developed the Digital Molecular Matter engine used by Lucas Film for some of their effects. Recently, Pixelux released an end user plug-in version of the Digital Molecular Matter for Maya. Read More

Palm Pixi specs include OpenGL ES 2.0 graphics

The upcoming Palm Pixi will have the new MSM7627 chipset from Qualcomm giving close to the same performance as the Pre. Featuring two ARM cores integrated as a single chip – a dedicated CPU core and a dedicated modem processor – 320MHz application DSP for multimedia supporting full 30 fps WVGA encode/decode, 200MHz hardware-accelerated 3D graphics core supporting OpenGL ES 2.0, high-resolution camera and integrated GPS.

gles2-bc - OpenGL ES 2.0 Backward Compatible

gles2-bc is an open source C++ library which makes the non-backward compatible OpenGL ES 2.0 API backward compatible to ease the development with various OpenGL ES APIs. The initial version was just released providing most of the backward compatibility. Read More

WebGL Support arrives in WebKit

Over the past weekend, and very quietly, support for WebGL started to appear in WebKit. If you are interested in seeing what WebGL is all about, watch this video on youtube. If you want to see WebGL it in action, you will need to check out a copy from the WebKit repository, as it is not available yet in the nightly builds. A list of browsers that use WebKit is available on Wikipedia. Some of the more popular browsers that use WebKit include Safari, Chrome, Omniweb, iCab, Android browser and the WebOS browser.

3D Format Wars-Will COLLADA be the next ‘STEP’ for the DCC industry?

As the 3D wars heat up, many folks see COLLADA's .dae format as a front runner for Digital Content Creation (DCC). In the Engineering CAD field the STandard for the Exchange of Product model data (STEP) has been declared as a clear winner by some. This article is an attempt to start a conversation on whether or not the COLLADA format is the next 'STEP' for the DCC industry. Read More

Khronos OpenCL Slide Presentations and Tutorials from Hotchips 2009 Now Online

The Khronos Group hosted a series of OpenCL tutorials at the Hotchips 2009 event in August on high performance chips. All of these OpenCL tutorials are now online in the Khronos Developers Library. Included are tutorials from AMD, EA, Intel, Nokia, NVIDIA, and of course the Khronos Group. Read More

HPCWire features OpenCL Promises and Potential

While OpenCL is very similar in many respects to NVIDIA's CUDA, it adds features to take advantage of other targets; and though it's quite complex, it has the potential to deliver very high performance, and is much easier than trying to map your computation into OpenGL or graphics primitives. So says Michael Wolfe, with over 30 years in both academia and industry on developing compilers, and is now a senior compiler engineer at The Portland Group, Inc., a wholly-owned subsidiary of STMicroelectronics, Inc.

NVIDIA Releases First OpenCL Performance Profiler for the GPU

NVIDIA released a new OpenCL Visual Profiler for Windows and Linux for developers. Leveraging the extensive performance instrumentation in NVIDIA's OpenCL drivers and hardware performance signals designed into NVIDIA GPUs, the OpenCL Visual Profiler provides developers with insight into performance bottlenecks and opportunities for optimization. NVIDIA also released a Best Practices guide for OpenCL. Read More

SC09 announces their exhibitor and first time exhibitor list

The World's Premier Super Computing event, SC09, will hold its 22nd annual event in Portland Oregon this November. This year, more than 275 exhibitors with 40 participating for the first time, have the SC09 organizers expecting a full house at the Oregon Convention Center. One of the first time exhibitors includes the Khronos Group. The Khronos Group will have booth #242 this year and will undoubtedly be extolling the virtues of OpenCL. You will find complete details of tutorials, wokrshops and sessions on the Khronos website. Read More

Next generation iPod touts OpenGL ES 2.0

Apple announced a minor upgrade to their iPods today with among other things, an upgrade to support OpenGL ES 2.0. Both the popular iPod Touch and the iPhone now supporting OpenGL ES 2.0 reinforces Apples intent to grab a bigger portion of the mobile gaming market. Read More

OpenTK 0.9.9-2 C# OpenGL bindings

OpenTK is an advanced, cross-platform library that provides Mono/.Net OpenGL, OpenGL ES, OpenAL and OpenCL bindings. The latest version adds support for all OpenGL ES extensions, significantly improves the OpenCL bindings and the ARB_imaging subset of OpenGL. A new compatibility module now allows Tao framework applications to run on OpenTK and improves behavior on broken xlib implementations. Finally, this version adds support for the iPhone platform via the MonoTouch project. Read More
