Abstract
A method of deriving intended thread data exchange patterns from source code includes identifying, based on a constant array, a pattern of data exchange between a plurality of threads in a wavefront. The constant array includes an array of source lane values identifying a thread location within the wavefront to read from for performing the pattern of data exchange. The pattern of data exchange is identified as a hardware-accelerated exchange pattern based on the constant array.
