std::experi...::simd::size(3) C++ Standard Libary std::experi...::simd::size(3) NAME std::experimental::simd::size - std::experimental::simd::size Synopsis static constexpr size_t size() noexcept; (parallelism TS v2) Returns the width (the number of values) of simd<T, Abi>. Example The actual output depends on target and compiler flags. // Run this code #include <experimental/simd> #include <cstdint> #include <iostream> namespace stdx = std::experimental; int main() { stdx::native_simd<std::int32_t> a = 1; std::cout << a.size() << '\n'; std::cout << reduce(a) << '\n'; } Possible output: 16 16 See also simd_size obtains the number of elements of a given ele- ment type and (parallelism TS v2) ABI tag (class template) size returns the width / number of elements [static] (parallelism TS (public static member function of v2) std::experimental::simd_mask<T,Abi>) http://cppreference.com 2024.06.10 std::experi...::simd::size(3)
