摘要
A system and method for verifying a memory consistency model for a shared memory multiprocessor computer systems generates random instructions to run on the processors, saves the results of the running of the instructions, and analyzes the results to detect a memory subsystem error if the results fall outside of the space of possible outcomes consistent with the memory consistency model. A precedence relationship of the results is determined by uniquely identifying results of a store location with each result distinct to allow association of a read result value to the instruction that created the read result value. A precedence graph with static, direct and derived edges identifies errors when a cycle is detected that indicates results that are inconsistent with memory consistency model rules.
