摘要： A loosely coupled multi-processor system including a plurality of terminals and corresponding processors. When a particular terminal tries to start a program, the corresponding processor sets the largest number of the terminals, which are serviceable, on the basis of the load status of the processors which are permanently watched by the OS (operating system) in a main memory. The processor compares this largest number with the number of terminals, which are in service at that time and when the number of the terminals, which are in service, is smaller than the largest number, processing by the terminal issuing a service demand begins. Alternatively, when the number of the terminals, which are in service, is equal to or greater than the largest number, the processor cannot treat the service demand from the terminal and reports this to a global processor. The global processor examines the load status indicator contained therein which shows the load status of each of the system processors; selects the processor having the lightest load status; and issues an order to treat the service demand from the requesting terminal to the selected processor having the lightest load. The processor, which has received the order, performs the processing of the service demand from the requesting terminal, based on the instruction from the global processor.
