A process for maintaining synchronization of processors that are executing a same plurality of applications in parallel includes interrupting a current task between processing two successive instructions of an application being processed when an interrupt request occurs to process another application. An intermediate state reached by the current task is saved when the interrupt request occurs, and a counter for each of the processors indicating a number of instructions processed by each of the processors is maintained. A processor is caused to issue a synchronization confirmation in response to a comparison result that the numbers of instructions processed are identical. The processor is caused to enter a wait state when its number of processed-instructions is the largest among the processors or to execute a procedure for processing the instructions until its processed-instruction counter reaches the largest number. |
