Parallelized version of existing algorithms (parallelism TS)
From cppreference.com
The C++ Extensions for Parallelism TS provides parallelized versions of the following 69 existing algorithms. Each of the following parallelized algorithms
- is declared in the
std::experimental::parallelnamespace, - does not participate in overload resolution unless
is_execution_policy<std::decay_t<ExecutionPolicy>>::valueistrue, and - has the same semantics as the corresponding existing algorithm in the C++ standard library, except as noted in the page on parallel algorithms.
