System for iteratively identifying available next higher priority tracks when identified track matching the task's native track priority is unavailable

Abstract

Embodiments are directed towards coordinating parallel execution of tasks. An ordered priority for each of a plurality of tracks may be established. Furthermore, each of a plurality of tasks may be assigned a native priority. A track for executing a task may be identified based on a match of the task native priority and a track priority. The task can execute at the identified track if the track is available. If the identified track is not available, then another track with a next higher priority than the previously identified track maybe iteratively identified. Next higher priority tracks may be iteratively identified until an available track is identified. If an available track is identified then the task can execute at the available track; otherwise, the task may be put into a wait mode before re-attempt to execute at the track with a priority that matches the task native priority.
