Title: Process control system
Inventor: UEDA MANABU
IPC: G06F9/46
Filed: 1989-12-20
Abstract: PURPOSE:To obtain a process control system which can satisfy requests of each process by switching dynamically the resources allocation of a process executed in parallel. CONSTITUTION:To a transmission line consisting of a coaxial cable 1, plural work stations 2 - 4 and a print server 5 are connected. In such a state, each process decides dynamically whether its own processing is ended before the end target time or not. When it is decided that the processing is ended before that time, the processing of a CPU is delivered to other process, and controlled so that its processing advances quickly. On the other hand, when it is decided that the own processing is not ended before the end target time, the occupancy time of the CPU is extended and controlled so that the processing of its own process is quickened. In such a manner, the end target time of each process is satisfied as the greatest common measure.
