Execute functor
in parallel according to the execution policy
.
A "functor" is a class containing the function to execute in parallel, data needed for that execution, and an optional execution_space
alias. Here is an example functor for parallel_for:
In the above example, WorkType
is any integer type for which a valid conversion from size_t
to IntType
exists. Its operator()
method defines the operation to parallelize, over the range of integer indices iwork=[0,work_count-1]
. This compares to a single iteration iwork
of a for
loop. If execution_space
is not defined DefaultExecutionSpace will be used.
