Abstract
A scheduling governor that regulates the number of scheduled tasks that are executed concurrently over a network computer system is presented. All task requests that are scheduled to be executed within a pre-specified interval of time, are serviced according to their priority. During heavy load times, the scheduling governor prevents overloads of the processing resources of the host computer by limiting the number of concurrently executing scheduled tasks to a pre-specified capacity dimension. Task requests that are unable to be run due to the governed cap on the number of allowed concurrently executing processes are given a priority to be executed once one of the fixed number of execution slots becomes available. Accordingly, the scheduling governor allows each scheduled task to be executed as close to its scheduled time as possible yet prevents system resource overload to improve efficiency and performance.
