The libstdc++ parallel mode is an experimental parallel implementation of many algorithms the C++ Standard Library.
Several of the standard algorithms, for instance
std::sort, are made parallel using OpenMP
annotations. These parallel mode constructs and can be invoked by
explicit source declaration or by compiling existing sources with a
specific compiler flag.
The following library components in the include
<numeric> are included in the parallel mode:
std::accumulate
std::adjacent_difference
std::inner_product
std::partial_sum
The following library components in the include
<algorithm> are included in the parallel mode:
std::adjacent_find
std::count
std::count_if
std::equal
std::find
std::find_if
std::find_first_of
std::for_each
std::generate
std::generate_n
std::lexicographical_compare
std::mismatch
std::search
std::search_n
std::transform
std::replace
std::replace_if
std::max_element
std::merge
std::min_element
std::nth_element
std::partial_sort
std::partition
std::random_shuffle
std::set_union
std::set_intersection
std::set_symmetric_difference
std::set_difference
std::sort
std::stable_sort
std::unique_copy
The following library components in the includes
<set> and <map> are included in the parallel mode:
std::(multi_)map/set<T>::(multi_)map/set(Iterator begin, Iterator end) (bulk construction)
std::(multi_)map/set<T>::insert(Iterator begin, Iterator end) (bulk insertion)
