ADAPTIVE PARTITIONING SCHEDULER FOR MULTIPROCESSING SYSTEM

A symmetric multiprocessing system includes multiple processing units and corresponding instances of an adaptive partition processing scheduler. Each instance of the adaptive partition processing scheduler selectively allocates the respective processing unit to run process threads of one or more adaptive partitions based on a comparison between merit function values of the one or more adaptive partitions. The merit function for a particular partition of the one or more adaptive partitions may be based on whether the adaptive partition has available budget on the respective central processing unit. The merit function for a particular partition associated with an instance of the adaptive partition scheduler also, or in the alternative, may be based on whether the adaptive partition has available global budget on the symmetric multiprocessing system.
