  • Patent number: 5682530
    Abstract: With a time-sharing-oriented operating system, resource management groups are hierarchically formed including a plurality of processes. Each resource management group includes a resource management process for managing resources allocated to its group, at least one process which is a descendant of the resource management process and not included in other resource management groups, and a resource management block for storing information on the resources managed by its own group. Resource management processes are linked to each other in accordance with parent-child relationships between the respective resource management groups to form a resource management tree. At the generation of a new resource management group, resources necessary for the newly generated resource management group are distributed from resources owned by a parent resource management group of the newly generated resource management group in accordance with the resource management tree.
