ABSTRACT:
A multi-processor system wherein a plurality of priority-designated central processor units (CPUs) are interconnected by a program control memory which operates to transfer control (linkage) information between CPUs in response to interrupt commands to enable the total processing capacity of the system to be allocated to the highest priority jobs. Each processor unit employs a job swapping control program which responds to an interrupt command from an external source or from a higher priority unit to cause program status data stored in the CPU to be transferred to the program control memory for holding or for passage to a lower priority CPU. The job swapping program also causes program status data from the higher priority CPU to be transferred from the control memory to the CPU to enable processing of a new job. On completion of the interrupt cycle, the control program effects exchange of status data to restore job assignments to the original CPUs.
