Detailed Description

template<typename T_Type, uint32_t T_width, typename T_Storage>
struct alpaka::Simd< T_Type, T_width, T_Storage >

Simd vector.

Attention

You should not use this type to create a buffer of SIMD vectors. The implementation is not ABI compatible between different API's. Using Simd data created on the host and used in the compute kernel will be undefined behaviour.

This class is designed to be used via SimdPtr via reinterpretation of contiguous scalar data.

Template Parameters

T_Type	data value type
T_width	number of lanes in the SIMD vector
T_Storage	wrapped native representation of the SIMD vector

ALPAKA_FN_HOST_ACC alpaka::Simd< T_Type, T_width, T_Storage >::Simd ( F && generator )

inlineexplicit

Initialize via a generator expression.

The generator must return the value for the corresponding index of the component which is passed to the generator.

This constructor is not constexpr because std::simd is using a reinterpret_cast during the initialization with a generator and complains that this is not allowed in constexpr functions.

Constructor for SIMD pack.

Attention

This constructor allows implicit casts.

This constructor is not constexpr because std::simd is using a reinterpret_cast during the initialization with a generator and complains that this is not allowed in constexpr functions.

inlineconstexpr

Shrink the number of elements of a vector.

Template Parameters

T_numElements

New width of the SIMD pack.

Parameters

startIdx

Index within the origin vector which will be the last element in the result.

Returns

T_numElements elements of the origin vector starting with the index startIdx. Indexing will wrapp around when the begin of the origin vector is reached.

std::string alpaka::Simd< T_Type, T_width, T_Storage >::toString ( std::string const separator = ",", std::string const enclosings = "{}" ) const

inline

create string out of the SIMD pack

Parameters

separator	string to separate components of the SIMD pack
enclosings	string with width 2 to enclose SIMD pack width == 0 ? no enclose symbols width == 1 ? means enclose symbol begin and end are equal width >= 2 ? letter[0] = begin enclose symbol letter[1] = end enclose symbol

example: .toString(";","|") -> |x;...;z| .toString(",","[]") -> [x,...,z]
