摘要：A hardware and/or software facility for controlling the order of operationsperformed by threads of a multithreaded application on a multiprocessing system is
provided. The facility may serialize or selectively-serialize execution of the multithreadedapplication such that, given the same input to the multithreaded application, themultiprocessing system deterministically interleaves operations, thereby producing thesame output each time the multithreaded application is executed. The facility divides theexecution of the multithreaded application code into two or more quantum specifying adeterministic number of operations, and the facility specifies a deterministic order inwhich the threads execute the two or more quantum. The deterministic number ofoperations may be adapted to follow the critical path of the multithreaded application.Specified memory operations may be executed regardless of the deterministic order,such as those accessing provably local data. The facility may provide dynamic bugavoidance and sharing of identified bug information.
