std::experimental::simd_size - cppreference.com

From cppreference.com

template< class T, class Abi = simd_abi::compatible<T> > struct simd_size;

 (parallelism TS v2)

If T is a vectorizable type and is_abi_tag_v<Abi> is true, provides the member constant value equal to the width (number of elements) of simd<T, Abi>, irrespective of whether simd<T, Abi> is supported or not. For any other types T and Abi, there is no member value.

If the program adds specializations for std::simd_size or std::simd_size_v(since C++17), the behavior is undefined.

Helper variable template

template< class T, class Abi = simd_abi::compatible<T> > constexpr std::size_t simd_size_v = simd_size<T, Abi>::value;
