ORDERED AND RELIABLE MAINTENANCE OF INTER-PROCESS RELATIONSHIPS IN A DISTRIBUTED MULTI-PROCESSOR

摘要

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