parallel_for()

template<class ExecPolicy , class FunctorType , class Enable = std::enable_if_t<is_execution_policy<ExecPolicy>::value>>

void Kokkos::parallel_for ( const std::string &  str, const ExecPolicy &  policy, const FunctorType &  functor  )

inline

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:

class FunctorType {
public:
  using execution_space = ...;
  void operator() ( WorkType iwork ) const ;
};

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.
