摘要

A computer system has several interconnected processors (P1, P2, P3) each associated with a memory (S1, S2, S3). The memories (S1, S2, S3) all have a common storage area (SB) to which the processors (P1, P2, P3) have access. In order to synchronize changes (BZ0, BZ1, BZ2) in the state of operation of the processors (P1, P2, P3) and/or to handle processor jobs in a synchronous manner, the first processor to reach a predetermined synchronization point (MP1, MP2; WP1 ... WP3) writes a data set in the common storage area, causing interrupt controllers (IC1, IC2, IC3) associated with the processors (P1, P2, P3) to generate interrupt signals and to initiate changes in the state of operation or synchronous job processing. The invention has applications in multiple processor systems, redundant computer systems and stored program control systems.
