Going to OSCON? Don't miss Gary Frost's Aparapi talk
If you're going to be at O'Reilly's OSCON in Portland this year, you should catch Gary Frost's Aparapi talk. Aparapi allows developers to code entirely in Java (via a data parallel API). At runtime, Aparapi is capable of converting Java bytecode to OpenCL so that it can be executed on the GPU. Gary's talk will contrast Aparapi with other OpenCL Java bindings, describe how it works, & walk through some real world examples. » Learn more about Aparapi.


DirectCompute Code Sample
This sample presents a highly optimized technique for accelerating separable filters using DirectCompute, with a fall back Pixel Shader path also provided. It also allows developers to easily create their own specific filters, using just a handful of user defined macros. » Learn More


CodeAnalyst Performance Analyzer Update Now Available
The latest update now allows Windows developers to use CodeAnalyst integrated into Visual Studio 2012. And now Linux developers have performance monitoring counter (PCM) events and Instruction-Based Sampling (IBS) and support for new processors and Linxu distributions. » Download the latest versions here

Very often a GPU kernel has to return a few values to the host for inspection. For example, to check optimization criterion, get a result of a dot product or similar reduction operator. The data copy from the video memory to the host memory is a costly operation on a discrete GPU and still on APU right now, disproportionally so for a small chunk of data.
It's possible to reduce such cost to nearly zero. Learn how
