Detailed Description

A parallel task to be passed to halide_do_parallel_tasks.

This task may recursively call halide_do_parallel_tasks, and there may be complex dependencies between seemingly unrelated tasks expressed using semaphores. If you are using a custom task system, care must be taken to avoid potential deadlock. This can be done by carefully respecting the static metadata at the end of the task struct.
