Thread program to determine the relationship between the methods, equipment and systems

The present invention provides a method for determining the relationship between program threads, device, and system, comprising: a first detection system generating thread migration by the first processor to the second processor, the first processor executing a first thread of a target a parallel program thread, the thread first moved to the second processor as the second thread; determining a first order relation between the thread and the second thread. Confirmation of the operating system in order to achieve the same scheduling software threads caused by migration on different processors, in turn, can determine the sequence relationship before and after the thread migration, and improve the accuracy of the parallel program debugging.
