ABSTRACT:
Monitoring system wide task dispatch allows dynamic adaptation to conditions of a system. A monitor tracks the total tasks currently dispatched to the system. In a system with multiple processing units, this monitor is centralized and collects information about tasks dispatched to each of the processing units. The monitor compares the total dispatched tasks against a threshold that has already been defined. Further dispatching of tasks to the system is regulated based on comparison of the total dispatched tasks against the threshold. If the comparison achieves a trigger condition (e.g., total dispatched tasks exceeding the threshold), then task dispatch is throttled. Throttling further task dispatching, as long as the threshold is exceeded, allows progress to continue without overwhelming the system.
