Abstract
The system synchronizes data processing systems coupled together using a synchronization operation that is only implemented as a function of events that necessitate synchronization. The system differentiates between the immediate synchronization of internal commands and the indirect synchronization of interrupt events. When an internal command appears, then the synchronization of the data processing systems takes place immediately after the command is executed. In the case of interrupt events, the synchronization operation takes place at defined program points such as block limits or program sections of programs so partitioned.
