std::experimental::simd

< cpp‎ | experimental‎ | simd
Defined in header <experimental/simd>
template< class T, class Abi = simd_abi::compatible<T> >
class simd;
 (parallelism TS v2)

The class template simd is a data-parallel type. The width of a given simd instantiation is a constant expression, determined by the template parameters.

An ABI tag is a type in the simd_abi namespace that indicates a choice of size and binary representation for objects of data-parallel type.

Template parameters

T - element type; an arithmetic type other than bool
Abi - tag type used to determine the number of elements and storage

Helper alias templates

template< class T, int N >
using fixed_size_simd = std::experimental::simd<T, std::experimental::simd_abi::fixed_size<N>>;
template< class T >
using native_simd = std::experimental::simd<T, std::experimental::simd_abi::native<T>>;
