AMD has released the ATI Stream SDK version 2.1, this new release adds support for the company's upcoming Llano processor and features OpenCL and OpenGL interoperability.
A new version of the ATI Stream software development toolkit has gone up on AMD's Developer Central site. AMD says this 2.1 release offers improved support for "developers creating software optimized for APU computing." APU, short for accelerated processing unit, is the company's pet name for chips that integrate both microprocessor and graphics processor cores—like Llano, which began sampling recently.
At the top of the new Stream SDK's feature list: OpenCL and OpenGL interoperability, an addition that purportedly helps "reduce the overhead of passing data for display purposes, enabling a richer and more responsive visual experience for the user." (You might recall version 2.0 of the Stream SDK also included OpenCL-OpenGL interoperability, but AMD only labeled that a "preview." This looks to be the full implementation.)
