Embodiments relate to managing tasks that when executed by a neural processor circuit instantiates a neural network. A neural task manager circuit within the neural processor circuit can switch between tasks in different task queues. Each task queue is configured to store a reference to a task list of tasks for instantiating a neural network. Each task queue can also be assigned a priority parameter. While the neural processor circuit is executing tasks of a first task list and prior to completion of each task, the neural task manager circuit can switch between task queues according to the priority parameters for execution of tasks of a second task list by the neural processor circuit. The neural processor circuit includes one or more neural engine circuits that are configured to perform neural operations by executing the tasks assigned by the task manager.
