Defined in header <experimental/simd>
template< class T >
struct is_simd;
(1) (parallelism TS v2)
template< class T >
struct is_simd_mask;
(2) (parallelism TS v2)
1) If T is a specialization of the simd class template, provides the member constant value equal true. For any other type, value is false.
2) If T is a specialization of the simd_mask class template, provides the member constant value equal true. For any other type, value is false.

Member constants

value
[static]
true if T is a simd/simd_mask type , false otherwise
(public static member constant)

Member functions

operator bool
converts the object to bool, returns value
(public member function)
operator()
(C++14)
returns value
(public member function)

type std::integral_constant<bool, value>

[edit] Example

#include <experimental/simd>
#include <iostream>
 
int main() 
{
    namespace stdx = std::experimental;
    std::cout
    << std::boolalpha
    << stdx::is_simd_v<stdx::simd<float>> << '\n';
    << stdx::is_simd_v<int> << '\n';
    << stdx::is_simd_mask_v<stdx::simd_mask<float>> << '\n';
    << stdx::is_simd_mask_v<int> << '\n';
}

Output:

true
false
true
false
