Extensions for parallelism

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::parallel namespace,
  • does not participate in overload resolution unless is_execution_policy<std::decay_t<ExecutionPolicy>>::value is true, and
  • has the same semantics as the corresponding existing algorithm in the C++ standard library, except as noted in the page on parallel algorithms
