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.
In a digital processing system having a central processing unit (CPU) and an operating system for executing a plurality of active application processes, the operating system allotting CPU resources to each process, each process including a plurality of sub-tasks, each sub-task being assigned one of a plurality of priority levels, the priority levels including a highest priority level and at least one lower priority level, a method of balancing the CPU load comprising the steps of:
In a digital processing system having at least one central processing unit (CPU) for executing a plurality of processes, each process including a plurality of sub-tasks, a method of balancing load on the at least one CPU comprising the steps of:
In a time-sharing digital processing system having a central processing unit for executing a plurality of non-communicating processes stored in memory, each process including a plurality of sub-tasks, a method of load balancing comprising the steps of:
In a digital processing system, including a central processing unit for executing a plurality of application processes, memory for storing instructions corresponding to the application processes, each of the processes including a plurality of sub-tasks, each having either a high or low priority level assigned thereto, a system for distributing load on the central processing unit comprising:
