Top Level Execution Policies

Policy	Description
RangePolicy	Each iterate is an integer in a contiguous range
MDRangePolicy	Each iterate for each rank is an integer in a contiguous range
TeamPolicy	Assigns to each iterate in a contiguous range a team of threads

Nested Execution Policies

Nested Execution Policies are used to dispatch parallel work inside of an already executing parallel region either dispatched with a TeamPolicy or a task policy.

Policy	Description
TeamThreadRange	Used inside of a TeamPolicy kernel to perform nested parallel loops split over threads of a team.
TeamVectorRange	Used inside of a TeamPolicy kernel to perform nested parallel loops split over threads of a team and their vector lanes.
ThreadVectorRange	Used inside of a TeamPolicy kernel to perform nested parallel loops with vector lanes of a thread.
