Macro Definition Documentation

◆ ALPAKA_NAMED_ARRAY_ACCESS

#define ALPAKA_NAMED_ARRAY_ACCESS ( functionName,
laneIdx )
Value:
constexpr reference functionName() requires(T_width >= laneIdx + 1) \
{ \
return (*this)[laneIdx]; \
} \
constexpr type functionName() const requires(T_width >= laneIdx + 1) \
{ \
return (*this)[laneIdx]; \
}

named lane access

Attention
The mapping from names x,y,z,w to memory indices differ from the mapping of an alpaka vector Vec. The availability of the naming methods depends on the SIMD width.

You can have access to the same lane index via different nonspecific naming.

lane index : 0, 1, 2, 3, ..., 9, 10, ... , 15
hexadecimal : s0, s1, s2, s3, ..., s9, SA, ... , SF
coordinate : x, y, z, w
color channel: r, g, b, a

#define ALPAKA_VECTOR_ASSIGN_OP ( op)
Value:
template<typename T_OtherStorage> \

{ \
this->asStorage() op rhs.asStorage(); \
return *this; \

constexpr SimdMask& operator op(concepts::LosslesslyConvertible<T_Type> auto const value) \
