AMD APP SDK v2.6 is officially released. Notable features are enhanced performance, multi-GPU support on Linux, inclusion of the Khronos C++ wrapper, use of OpenCL kernels in data-driven applications and a preview of OpenCL 1.2 and the static C++ kernel language.
The Khronos Group has posted several presentation slide sets online from SIGGRAPH Asia 2011. Included are slides sets covering KITE, OpenGL, OpenGL ES, OpenGL SC, OpenVG, OpenMAX, OpenSL ES, StreamInput, WebGL and WebCL.
In this talk form the 2011 LLVM Developers Meeting, Intel presents their OpenCL SDK 1.5 and its core technology the vectorizer compiler.
The video presents an overview of the implicit vectorization module and discusses experience with the LLVM compiler toolkit. The presenter also presents some of the design decisions and and plans for future features (future instruction sets, vector select, predicated instructions, etc).
The slide sets from Devcon 5 in Santa Clara in December 2011 are now online. There are a total of 3 slide sets covering WebGL and WebCL.
A paper recently published by the Astronomical Society of Australia on how GPGPUs are dramatically changing the landscape of high performance computing in astronomy.This paper identifies and investigates several key decision areas, with a goal of simplifying the early adoption of GPGPU in astronomy. The merits of OpenCL are considered as an open standard in order to reduce risks associated with coding in a native, vendor-specific programming environment, and present a GPU programming philosophy based on using brute force solutions.
In a quiet post on the LLVMdev mailing list, it was announced that AMD is going Open Source with the AMD IL Code Generator which is compatible with LLVM 2.9. Also, video and slides from the recent 2011 LLVM Developers' Meeting are starting to appear online. Including SKIR: Just-in-Time Compilation for Parallelism with LLVM, Univeristy of Colorado; Intel OpenCL SDK Vectorizer, Intel; Polly - First successful optimizations - How to proceed?, ENS/INRIA and finally Symbolic Testing of OpenCL Code from Imperial College London.
AMD has released an interesting white paper on OpenCL and the Future of Accelerated Application Performance, as seen through the eyes of their FirePro product lineup. Whether you are a beginner OpenCL developer or an advanced developer, AMD has done a good job of making this a worthwhile read.
The Khronos Group announced a new initiative to create an open, royalty-free standard for cross platform acceleration of computer vision applications. In response to requests and proposals from members, Khronos has created a vision working group to develop a hardware acceleration API using the proven Khronos development process and aiming for a first public release within 12 months. Any interested company is welcome to join Khronos to make contributions, influence the direction of the specification and gain early access to draft specifications before public release. The vision working group will commence work during January 2012.
The first Los Angeles WebGL Meetup was a big success. For the first meetup, there was a presentation on the current state of interactive web 3D (demo and slides) as well as on the J3D WebGL 3D engine (slides). There are plans on doing another meetup in January. If you are in the area and want to learn about next-generation 3D in the browser, or give a presentation please contact the organizers of the LA WebGL meetup.
