Data-parallel vector library

Defined in header <experimental/simd>

Main classes

simd (parallelism TS v2)	data-parallel vector type (class template)
simd_mask (parallelism TS v2)	data-parallel type with the element type bool (class template)

ABI tags

Defined in namespace std::experimental::simd_abi
scalar (parallelism TS v2)	tag type for storing a single element (typedef)
fixed_size (parallelism TS v2)	tag type for storing specified number of elements (alias template)
compatible (parallelism TS v2)	tag type that ensures ABI compatibility (alias template)
native (parallelism TS v2)	tag type that is most efficient (alias template)
max_fixed_size (parallelism TS v2)	the maximum number of elements guaranteed to be supported by fixed (constant)
deduce deduce_t (parallelism TS v2)	obtains an ABI type for given element type and number of elements (class template)

Alignment tags

element_aligned_tag element_aligned (parallelism TS v2)	tag type that indicates the alignment of the elements (class)
vector_aligned_tag vector_aligned (parallelism TS v2)	tag type that indicates the alignment of the vector type (class)
overaligned_tag overaligned (parallelism TS v2)	tag type that indicates the specified alignment (class template)

Where expression

const_where_expression (parallelism TS v2)	selected elements with non-mutating operations (class template)
where_expression (parallelism TS v2)	selected elements with mutating operations (class template)
where (parallelism TS v2)	produces const_where_expression and where_expression (function template)

Casts

simd_cast static_simd_cast (parallelism TS v2)	element-wise static_cast (function template)
to_fixed_size to_compatible to_native (parallelism TS v2)	element-wise ABI cast (function template)
split (parallelism TS v2)	splits single simd object to multiple ones (function template)
concat (parallelism TS v2)	concatenates multiple simd objects to a single one (function template)

Algorithms

min (parallelism TS v2)	element-wise min operation (function template)
max (parallelism TS v2)	element-wise max operation (function template)
minmax (parallelism TS v2)	element-wise minmax operation (function template)
clamp (parallelism TS v2)	element-wise clamp operation (function template)

Reduction

reduce (parallelism TS v2)	reduces the vector to a single element (function template)
hmin (parallelism TS v2)	returns the minimum element (function template)
hmax (parallelism TS v2)	returns the maximum element (function template)

Mask reduction

all_of any_of none_of some_of (parallelism TS v2)	predicates on the number of true values (function template)
popcount (parallelism TS v2)	returns the number of true values (function template)
find_first_set find_last_set (parallelism TS v2)	returns the position of the first or last true value (function template)

Traits

is_simd is_simd_mask (parallelism TS v2)	checks if a type is a simd or simd_mask type (class template)
is_abi_tag (parallelism TS v2)	checks if a type is an ABI tag type (class template)
is_simd_flag_type (parallelism TS v2)	checks if a type is a simd flag type (class template)
simd_size (parallelism TS v2)	obtains the number of elements of a given element type and ABI (class template)
memory_alignment (parallelism TS v2)	obtains an appropriate alignment for vector_aligned (class template)
rebind_simd resize_simd (parallelism TS v2)	change element type or the number of elements of simd or simd_mask (class template)
