template<typename T_Type, uint32_t T_width, typename T_Storage>
struct alpaka::SimdMask< T_Type, T_width, T_Storage >
Simd mask vector.
- Attention
- You should not use this type to create a buffer of SIMD masks. The implementation is not ABI compatible between different API's. Using Simd masks created on the host and used in the compute kernel will be undefined behaviour.
This class is designed to be used within a kernel together with the where() operation.
- Template Parameters
-
| T_Type | data value type the mask should be applied to |
| T_width | number of lanes in the SIMD mask vector |
| T_Storage | wrapped native representation of the SIMD mask |
Definition at line 76 of file SimdMask.hpp.
template<typename T_Type, uint32_t T_width, typename T_Storage>
template<typename F>
Initialize via a generator expression.
The generator must return the value for the corresponding index of the component which is passed to the generator.
- Note
- The generator needs to have the function interface bool generator(uint32_t id).
Definition at line 104 of file SimdMask.hpp.
template<typename T_Type, uint32_t T_width, typename T_Storage>
template<typename... T_Args>
Constructor for SIMD pack.
- Attention
- This constructor allows implicit casts.
- Parameters
-
| args | value of each lane index, x,y,z,... |
A constexpr vector should be initialized with {} instead of () because at least CUDA 11.6 has problems in cases where a compile time evaluation is required.
constexpr auto vec1 =
Simd{ 1 };
constexpr auto vec2 =
Simd{ 1, 2 };

template<typename T_Type, uint32_t T_width, typename T_Storage>
reduce all elements to a single value
For better numerical stability a tree reduce algorithm is used.
- Template Parameters
-
| BinaryOp | binary functor executed to reduce the range The binary operation must be associative. |
- Returns
- the type of the result depends on the binary functor

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]
