RenderStream announced its AMD Radeon based 21.6 teraflop servers and workstations for OpenCL / OpenGL / Brooks based applications and product development. The workstations offer 1,536 stream processors and eight GPUs per system, which provide access to 12,288 cores and 21.6 TFLOPS of aggregate compute power. As an example from information security, the HD 6970 and HD 6990 based VDACTr8 evaluated over 45 billion solutions per second versus 18 billion for the GTX 580 based systems, depending on the implementation.
WebGL pays strong attention to security - just as any web technology should. With growing recognition of WebGL in the press, we thought we would summarize Khronos' work and stance on this important topic.
- Khronos agrees that security is a vitally important consideration for any web standard. WebGL was architected with security in mind from the ground up.
- All WebGL implementations already necessarily contain safeguards which prevent out-of-range memory accesses during rendering operations and access of uninitialized memory; please see here and here. These safeguards are tested by the WebGL conformance suite.
- Defense against denial of service attacks is still evolving in WebGL implementations. Khronos has specified an extension to OpenGL and OpenGL ES, GL_ARB_robustness, designed to prevent denial of service and out-of-range memory access attacks from WebGL content, preventing any possibility of using WebGL to execute malware on a user's machine.
- GL_ARB_robustness has already been deployed by some GPU vendors and Khronos expects it to be deployed rapidly by others. Browsers can check for the presence of this extension before enabling WebGL content. This is likely to become the deployment mode for WebGL in the near future.
- The ability to incorporate cross-domain images into WebGL scenes provides great utility to developers, but the WebGL working group is considering requiring Cross Origin Resource Sharing (CORS) opt-in or other mechanisms to prevent possible future abuse of this capability.
- The WebGL working group has been working closely with the GPU vendors in the Khronos group to make accelerated WebGL implementations secure and WebGL is influencing GPUs to provide even more flexible security options in the future.
- There are no known WebGL exploits and Khronos will continue to place close attention to technical and ecosystem opportunities to ensure WebGL is a secure technology that can be used with confidence.

Raspberry Pi is a functioning computer that fits in your pocket, for only $25. David Braben, a well-known video game developer who runs the UK studio Frontier, has spent his spare time trying to answer the question: "How to get young students excited about computers and more specifically, computer sciences like programming and hardware repair?" David believes price point is a major barrier for most schools from getting the equipment needed to teach kids the more advanced computer skills. But what can you get for $25? A lot! Provisional specs include an 700MHz ARM11, 128MB of SDRAM, OpenGL ES 2.0, 1080p30 H.264 high-profile decode, composite and HDMI video output, USB 2.0, SD/MMC/SDIO memory card slot, to start with.
Jon Peddie Research has written up a great review of the Khronos Groups new StreamInput API. Kathleen Maher writes "There is a tipping point out there somewhere and it doesn’t seen too far away. The Internet of Things is practically building itself. Khronos’ first role will be to help developers take advantage of sensors for mobile and console devices, but the day is not far off when the applications for sensors broaden further into our everyday lives and capabilities."
If you missed the San Francisco WebGL Meetup in April, you now have a chance to find out what it was all about. Complete with pictures and lots of details from the meetup, this review is well done and paints a great picture!
The WebGL and COLLADA powered OurBricks lets you share and interact with 3D content in a modern webbrowser. Today they announce a design competition for 3D artists. The theme is “Modern Life.” Deadline for submissions is May 16 at 12pm PST.
AMD announced the Radeon E6760 embedded discrete graphics processor. The AMD Radeon E6760 GPU is the first of its kind to offer embedded system designers the combination of OpenCL support along with support for six independent displays. The Radeon E6760 is based on a published Khronos Specification, and is expected to pass the Khronos ConformanceTestingProcess. Current conformance status can be found at http://www.khronos.org/conformance.
AMD has unveiled its lineup of keynote speakers who will address developers at its upcoming AMD Fusion Developer Summit, a list that includes ARM executive John Davies. AMD on Tuesday said that Davies, vice president of technology in ARM's Media Processing division, will discuss ARM’s history of heterogeneous computing, its market strategy and, most of all, its support for AMD’s OpenCL and other open industry standards.
Apple announced Final Cut Pro X at the Final Cut Pro User Group Supermeet at the NAB conference. The new version of the professional video editing application will include 64-bit and OpenCL support.
Sony Creative Software announced the availability of Vegas™ Pro 10.0d. The award-winning NLE now includes improved closed captioning options, comprehensive 3D solutions, support for AMD's ATI graphics chipsets using OpenCL™ as well as an improved track group workflow.
