Zusammenfassung:Methods, apparatuses, and computer program products for instruction weighting for performance profiling in a group dispatch processor are described. In a particular embodiment, a post processing profiler retrieves an execution sample including an instruction address of a youngest instruction in a dispatch group that has completed execution in a group dispatch processor and a number of instructions in the dispatch group. In the particular embodiment, the post processing profiler identifies, based on the instruction address of the youngest instruction and the number of instructions in the dispatch group, all of the instructions that are in the dispatch group at the time that the dispatch group completes execution. In the particular embodiment, the post processing profiler applies within an execution profile, the result of the execution sample, equally to all of the identified instructions that are in the dispatch group.
