Episode 3 - Building an OpenCL Project (PDF)
In this episode we cover some questions that were asked on the forums about double-precision arithmetic, object oriented programming, clarification on global and local work groups and types of scientific calculations that are amenable to GPU computing. In addition, we'll go over in more detail how to query devices for specific information and features and walk through an example of an OpenCL calculation in Xcode.
