Abstract
Exemplary systems and methods include a distribution device that maintains a dock rate and distributes a series of tasks to a group of execution devices. Each task has a plurality of samples per frame associated with a time stamp indicating when the task is to be executed. The execution devices execute the series of tasks at the times indicated and adjust the number of samples per frame in relation to the dock rate maintained by the distribution device.
