摘要： A symmetric multiprocessing fault-tolerant computer system [100] controls memory access in a symmetric multiprocessing computer system. To do so, virtual page structures are created, where the virtual page structures reflect physical page access privileges to shared memory for processors in a symmetric multiprocessing computer system. Access to shared memory is controlled based on physical page access privileges reflected in the virtual paging structures to coordinate deterministic shared memory access between processors in the symmetric multiprocessing computer system. A symmetric multiprocessing fault-tolerant computer system may use duplication or continuous replay.

摘要： A fault-tolerant computer system includes at least two servers, each of which is configured to perform a first set of operations. Each of the two servers communicate with a computer that does not perform the first set of operations. In the event of a failure of a component of the system, determining which of the servers will continue to perform the first set of operations based on communication with the computer (100)
