Extensions for parallelism v2
SIMD library
std::experimental::simd_mask
static constexpr size_t size ( ) noexcept ;
(parallelism TS v2)

Returns the width (the number of values) of simd_mask<T, Abi> .

Example

The actual output depends on target and compiler flags.

Run this code 
#include <experimental/simd>
#include <iostream>
namespace stdx = std::experimental;
 
int main()
{
    stdx::native_simd_mask<int> a { true };
    std::cout << a.size() << '\n';
    std::cout << popcount(a) << '\n';
}

Possible output: 

16
16
