AMD and Mentor go home winners from ESC 2011

AMD and Mentor Graphics Corp. were named by winners consulting firm VDC Research Group Inc. of the firm's "Embeddy" awards for best in show at the 2011 Embedded Systems Conference. AMD took home the hardware Embeddy for its embedded G-Series application processor unit (APU) product. AMD's Radeon E6760 is the first graphics chip for embedded systems to support Microsoft's DirectX 11, the OpenCL standard and up to six simultaneous displays, according to AMD. Mentor Graphics was awarded a software Embeddy for its Embedded Sourcery System Analyzer technology.

RenderStream 21.6 Teraflop Servers and Workstations for OpenCL

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 Security

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.

  1. Khronos agrees that security is a vitally important consideration for any web standard. WebGL was architected with security in mind from the ground up.
  2. 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.
  3. 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.
  4. 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.
  5. 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.
  6. 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.
  7. 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 and OpenGL ES 2.0

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.
