Abstract: Disclosed methods, systems, and computer program products embodiments include synchronizing a group of workitems on a processor by storing a respective program counter associated with each of the workitems, selecting at least one first workitem from the group for execution, and executing the selected at least one first workitem on the processor. The selecting is based upon the respective stored program counter associated with the at least one first workitem.

Abstract: A method, system, and computer program product synchronize a group of workitems executing an instruction stream on a processor. The processor is yielded by a first workitem responsive to a synchronization instruction in the instruction stream. A first one of a plurality of program counters is updated to point to a next instruction following the synchronization instruction in the instruction stream to be executed by the first workitem. A second workitem is run on the processor after the yielding.
