ABSTRACT:
A method and apparatus for prioritized load-balancing among non-communicating processes in a time-sharing system involves a Load Balancing Repository (LBR) which interfaces with each process that is actively addressed by the CPU. A scheduler within each process provides the LBR with a load distribution for that process representing the ratio of high-priority sub-task load to low-priority sub-task load. The LBR determines a target ratio in the form of an aggregate load distribution ratio. The target ratio is reported back to each active process. For processes which are occupied with a relatively low proportion of high priority sub-tasks and which therefore exhibit a load distribution that is below the target ratio, the process scheduler will give up a portion of the time slice allotted to that process by the operating system when the load distribution of that process reaches the target ratio. Thus, CPU resources will be applied more frequently to processes which are occupied with a relatively high proportion of high priority sub-tasks.
