Japan takes top spot with K Computer running at 8.16 Petaflops

This June saw an exciting Top 500 Supercomputer Site list. Japan bumped China out of first place with their 8162 TeraFlop 548,352 core machine. Interesting with this machine is that it runs on CPU's only, no GPU's. NVIDIA holds on to 3 of the top 10 spots. For complete stats and more information on the top ten fastest Super Computers, read the latest post from top500.org.

SmallLuxGPU 2.0 written in OpenCL video release

A new video about SmallLuxGPU 2.0 and Blender Exporter LiveMod. SmallLuxGPU is a LuxRays demo and a LuxRender 'proof of concept'. SmallLuxGPU is released under GPL license. SmallLuxGPU 2.0 renderer is 100% written in OpenCL and includes the support for:

  • Multi-OS (i.e. Win, Linux, MacOS, etc.);
  • OpenCL multi-platforms (i.e. Intel + NVIDIA, etc.);
  • OpenCL multi-devices (i.e. CPUs+GPUs, etc.);
  • Metropolis Light Transport;
  • Path tracing with next event MiS (i.e. multiple importance sampling);
  • Blender integration with LiveMode: interactive materials/lights/objects editing.

Call for Authors for upcoming OpenGL Insights book

Patrick Cozzi and Christophe Riccio invite you to contribute to OpenGL Insights, a book containing original articles on OpenGL, OpenGL ES, and WebGL techniques by the OpenGL community and for the OpenGL community: from game programmers to web developers to researchers. OpenGL Insights will be published by A K Peters Ltd. / CRC Press in time for SIGGRAPH 2012. Given the wide array of OpenGL platforms, from Mac desktops to Android phones to web browsers, we invite you to submit article proposals on all aspects of OpenGL development, including performance tuning, recent GL features/extensions, application architecture, vendor-specific techniques, WebGL, and interoperability with other APIs. We are interested in proposals based on your unique real-world experience using OpenGL.

Mirada and radical.media director Chris Milk create WebGL immersive landscape experience

Mirada and Chris Milk have teamed up to create an ambitious transmedia interactive music video experience called "3 Dreams of Black" for Danger Mouse and composer Daniele Luppi's Spaghetti Western-inspired concept album ROME featuring Jack White and Norah Jones. "'3 Dreams of Black' has made it clear that WebGL brings a lot of possibilities, but at the same time requires a level of technical knowledge that just a few studios have," said Ricardo Cabello, Lead Data Arts Developer, Google Creative Lab. You can watch a preview on YouTube.

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.

Turning ‘natural interface’ input into a new data standard

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."
