Tutorial: Adventures in OpenCL Part 2: Particles with OpenGL

In this episode of Adventures in OpenCL tutorials, we cover OpenCL context sharing with OpenGL. We make a simple particle system to demonstrate this feature. One of the most important aspects of this feature is the time we can save by doing rendering and calculations on the same memory in the GPU, this means we don’t need to copy data back and forth!

OpenCL™ Optimization Case Study: Simple Reductions

AMD Developer central just released an OpenCL optimization case study on SImple Reductions. Strategies examined for efficiently mapping reductions onto the ATI Radeon™ HD 5870 GPU and AMD Phenom™ II X4 965 CPU. Taking advantage of properties of the reduction being performed, as well as matching the style of reduction to the hardware platform, can result in performance improvements of up to 15x, compared to naive code.

AMD releases ATI SDK v2.2 with OpenCL support

AMD has released an update to their ATI Stream SDK. This brings OpenCL 1.1 support to the table among many other enhancements. Although most of the improvements revolve around OpenCL, there is a host of additional hardware and OS support included also. The ATI Stream SDK v2.2 product is based on a published Khronos Specification, and is expected to pass the Khronos Conformance Testing Process. Current conformance status can be found at www.khronos.org/conformance.
