Using buffer iteration end

[Renan1]

Looking at the oneAPI examples on jupyter notebook, when creating iterations buffers, I didn`t understand why only a end for buf_in was created and not for the others as well.

auto keys_begin = oneapi::dpl::begin(buf_in);
auto keys_end = oneapi::dpl::end(buf_in);
auto vals_begin = oneapi::dpl::begin(buf_seq);
auto result_key_begin = oneapi::dpl::begin(buf_out_keys);
auto result_vals_begin = oneapi::dpl::begin(buf_out_vals);

(It is a code from the oneDPL - Extension APIs.ipynb)

Hi,

Thanks for posting in Intel communities.

Every parallel algorithm in Extension API has fixed default parameters and we cannot change syntax.

For example please refer to below syntax of reduce_by_segment:

reduce_by_segment(Policy&& policy, InputIterator1 first1, InputIterator1 last1, InputIterator2 first2,

         OutputIterator1 result1, OutputIterator2 result2, BinaryPred binary_pred, BinaryOperator binary_op)

As each reduction is computed with a reduction operation for a subsequence of values, which are determined by keys.

Thanks & Regards,

Noorjahan.
