Abstract
Systems and methods may process a single atomic operation. An instruction set may be generated to replace a plurality of atomic operations with a single atomic operation. The instruction set may include an accumulation instruction to compute a prefix sum for a plurality of initial values associated with a plurality of processing lanes to generate a plurality of accumulated values. The instruction set may also include a broadcast instruction to return a pre-existing value to be added with each of the plurality of accumulated values to generate a plurality of intermediate accumulated values. In one example, a graphics processor may execute the instruction set to process the single atomic operation.
