Abstract
In a multiprocessor system, a method, apparatus, and article of manufacture for maintaining the proper sequence of store/write operations between multiple processors to remote I/O devices without requiring changes to application software. A synchronizer is employed to synchronize write operations to the remote I/O device, and the write operations are synchronized individually upon detection and emulation, or as a group upon detection of the release of a mutual exclusion lock.
