# std::experimental::simd_abi::max_fixed_size

From cppreference.com
< cpp‎ | experimental‎ | simd

Defined in header `<experimental/simd>` |  |
template< class T > inline constexpr int max_fixed_size = /*implementation-defined*/; |  | (parallelism TS v2)

The value of max_fixed_size<T> declares that an instance of simd<T, fixed_size<N>> with N <= max_fixed_size<T> is supported by the implementation. The value of max_fixed_size<T> is at least 32.

### Notes

It is unspecified whether an implementation supports simd<T, fixed_size<N>> with N > max_fixed_size<T>. The value of max_fixed_size<T> may depend on compiler flags and may change between different compiler versions.
