Sum multi reducer class template. More...

Detailed Description

template<typename MULTI_REDUCE_POLICY_T, typename T>
struct RAJA::MultiReduceSum< MULTI_REDUCE_POLICY_T, T >

Sum multi reducer class template.

Usage example:

  Real_ptr data = ...;
  Index_ptr bins = ...;
  Real_ptr sum_vals = ...;

  MultiReduceSum<multi_reduce_policy, Real_type> my_sums(num_bins, init_val);

  forall<exec_policy>( ..., [=] (Index_type i) {
     my_sums[bins[i]] += (data[i]);
  }

  for (size_t bin = 0; bin < num_bins; ++bin) {
     sum_vals[bin] = my_sums[bin].get();
  }
