Abstract

A system for efficiently verifying compliance with a memory consistency model includes a test module and an analysis module. The test module may coordinate an execution of a multithreaded test program on a test platform. If the test platform provides an indication of the order in which writes from multiple processing elements are performed at shared memory locations, the analysis module may use a first set of rules to verify that the results of the execution correspond to a valid ordering of events according to a memory consistency model. If the test platform does not provide an indication of write ordering, the analysis module may use a second set of rules to verify compliance with the memory consistency model.
