Just as the \kcode{for} and \kcode{do} constructs were combined
|
|
with the \kcode{parallel} construct for convenience, so too, the combined
|
|
\kcode{parallel masked taskloop} and
|
|
\kcode{parallel masked taskloop simd}
|
|
constructs have been created for convenience when using the
|
|
\kcode{taskloop} construct.
|
|
|
|
In the following example the first \kcode{taskloop} construct is enclosed
|
|
by the usual \kcode{parallel} and \kcode{masked} constructs to form
|
|
a team of threads, and a single task generator (primary thread) for
|
|
the \kcode{taskloop} construct.
|
|
|
|
The same OpenMP operations for the first taskloop are accomplished by the second
|
|
taskloop with the \kcode{parallel masked taskloop}
|
|
combined construct.
|
|
The third taskloop uses the combined \kcode{parallel masked taskloop simd}
|
|
construct to accomplish the same behavior as closely nested \kcode{parallel masked},
|
|
and \kcode{taskloop simd} constructs.
|
|
|
|
As with any combined construct the clauses of the components may be used
|
|
with appropriate restrictions. The combination of the \kcode{parallel masked} construct
|
|
with the \kcode{taskloop} or \kcode{taskloop simd} construct produces no additional
|
|
restrictions.
