<p>This section covers the high-level interface to the
task scheduler. The Task Scheduler section covers the low-level interface. The
high-level interface lets you easily create groups of potentially parallel
tasks from functors or lambda expressions. The low-level interface permits more
detailed control, such as control over exception propagation and affinity.
