Abstract: An apparatus and method, using an inter-processor lock to control access to inter-process relationship data structures in the memory (3a, 3b, ..., 3n) of each processor (2a, 2b, ..., 2n) in a multiprocessor system (1). The apparatus and method insure that each inter-process relationship is modified in the same sequence on each processor (2a, 2b, ..., 2n). The apparatus and method also insure that an inter-process relationship is maintained in a consistent state in the face of failure of any of the processors (2a, 2b, ..., 2n).
