Pizza scheduler

Causing a processor to execute a plurality of tasks includes determining a count for each task to be executed, determining a total count representing a sum of all counts for all tasks to be included in a run list, and constructing the run list by distributing corresponding entries for each task within the run list a number of times in accordance with each task's weighting factor. The weighting factor corresponds to a ratio of the each task's count with respect to a total count. Causing a processor to execute a plurality of tasks may also include executing the tasks in the run list in a round-robin manner where a particular entry in the run list is skipped in response to a corresponding task having previously relinquished a slot prior to expiration of time allotted for the task to run in the slot.
