Bryan Catanzaro, NVIDIA Research talks discuss the CUDA and OpenCL programming models, GPU architecture, and how to write high performance code on GPUs, illustrating with case studies from application domains such as image and video processing.
The SuperShaper is a small free tool that let's you explore the Super Formula in real-time. It uses OpenCL1.0 to evaluate the formula and OpenGL3.2 for rendering. For maximum performance OpenCL and OpenGL share buffers if possible. The latest version supports any OpenCL capable device in the system (CPU or GPU).
An in-depth comparison of OpenCL and CUDA with a strong running conversation. Take look and add your opinions.
Michael Bien has finished an OpenCL pack for NetBeans. Features include an OpenCL Editor with syntax highlighting code completion and CL reference pages integration, OpenCL compiler integration, In-editor annotations of compiler warnings and errors updated as you type and JOCL project template. Java 7 is required so you will need the Java 7 package on Google Code.
SIGGRAPH 2011 in Vancouver last week had a very high level of interest in OpenCL™ as demonstrated by SIGGRAPH attendees. The Exhibitor Tech Talk on “OpenCL and OpenGL/DirectX interoperability” presented by Olivier Zegdoun of AMD’s ISV Workstation team had seating for over 90 attendees and was standing room only. The OpenCL Birds-of-a-Feather with presentations from AMD, Intel, Nvidia and Codeplay over 200 attendees, and when asked who was already using OpenCL approximately half of the attendees raised their hands.
The presentations slides used at the SIGGRAPH 2011 Khronos Group OpenCL and OpenGL BOFs are now available.
AMD Demo of Optis THEIA VR using OpenCL on an AMD FirePro V7900 at the AMD Booth at SIGGRAPH 2011 in Vancouver. The real-time rendered Bentley model is created from six views folded into a box, with stitched edges to become a fully interactive environment. This process enables designers and engineers to analyze and optimize the lighting performance of future products while increasing design productivity.
Not sure where to start at SIGGRAPH 2011? Make your first stop at the Khronos Group Pavilion. Lots of give-aways and lots of demo's from ARM (665), Codeplay (766), DMP (664), Fixstars (667) and HUONE (762) all part of the Khronos Pavilion (663 & 764). Stop in to say Hi and learn about WebGL, OpenCL, OpenGL, OpenGL ES and COLLADA.
The Khronos Group will be holding three of the five SIGGRAPH BOFs today, August 10th. Starting off the show at 10am be sure not to miss the WebGL BOF in the Vancouver Convention Centre - Room 122 (West Building). Meet and greet some of the developers behind WebGL. Moving along to OpenCL in the Pan Pacific Hotel Crystal Ballroom B&C at 1:30PM. Lots of prizes to here for those that really know their OpenCL. Finally, at 4PM, also in the Pan Pacific Hotel Crystal Ballroom B&C, the much anticipated OpenGL. Even more prizes for those OpenGL trivia buffs. We hope to see all of you there today!
Imagination Technologies is working with Vector Fabrics BV to apply parallelization to software to be distributed across application processors that include PowerVR SGX graphics cores. The use of the OpenCL-based vfEmbedded code development, analysis and parallelization tool will be demonstrated in the booth of Imagination Technologies at SIGGRAPH this week.
