\section{The \code{parallel master taskloop} Construct}

\label{sec:parallel_master_taskloop}

In the OpenMP 5.0 Specification several combined constructs containing

the \code{taskloop} construct were added.

Just as the \code{for} and \code{do} constructs have been combined

with the \code{parallel} construct for convenience, so too, the combined

\code{parallel}~\code{master}~\code{taskloop} and

\code{parallel}~\code{master}~\code{taskloop}~\code{simd}

constructs have been created for convenience.

In the following example the first \code{taskloop} construct is enclosed

by the usual \code{parallel} and \code{master} constructs to form

a team of threads, and a single task generator (master thread) for

the \code{taskloop} construct.

The same OpenMP operations for the first taskloop are accomplished by the second

taskloop with the \code{parallel}~\code{master}~\code{taskloop}

combined construct.

The third taskloop uses the combined \code{parallel}~\code{master}~\code{taskloop}~\code{simd}

construct to accomplish the same behavior as closely nested \code{parallel master},

and \code{taskloop simd} constructs.

As with any combined construct the clauses of the components may be used

with appropriate restrictions. The combination of the \code{parallel}~\code{master} construct

with the \code{taskloop} or \code{taskloop}~\code{simd} construct produces no additional

restrictions.
