cuda::experimental::stf::logical_data

Defined in include/cuda/experimental/__stf/internal/backend_ctx.cuh

template<class T> class logical_data

Represents typed logical data.

Template Parameters: T – The type of the underlying data.

Execution place getter

inline const shape_t &shape() const

Instance getter for a given instance or the default instance

inline decltype(auto) instance(instance_id_t instance_id)

inline decltype(auto) instance(task &tp)

Assign a symbolic name for this object

inline logical_data &set_symbol(::std::string str)

Select a custom allocator for this logical data

inline logical_data &set_allocator(block_allocator_untyped custom_allocator)

Get hash value

inline size_t hash() const

Return a task_dep<T> object for reading and/or writing this logical data.

tparam Pack: Additional parameter types for task_dep<T>’s constructor, if any

param pack: Additional arguments for task_dep<T>’s constructor, if any

return: task_dep<T> The object encapsulating access

template<typename ...Pack> inline auto read(Pack&&... pack) const

template<typename ...Pack> inline auto write(Pack&&... pack)

template<typename ...Pack> inline auto rw(Pack&&... pack)

template<typename ...Pack> inline auto relaxed(Pack&&... pack)

template<typename Op, typename ...Pack> inline auto reduce(Op, no_init, Pack&&... pack)

template<typename Op, typename ...Pack> inline auto reduce(Op, Pack&&... pack)

Public Types

using element_type = T : Alias for T

using shape_t = shape_of<T>: Alias for shape_of<T>

Public Functions

logical_data() = default: Default constructor.

inline logical_data(logical_data_untyped &&u)

Constructor from an untyped logical data.

Warning : no checks are done to ensure the type used to create the untyped logical data matches, it is the responsibility of the caller to ensure this is a valid conversion

template<typename U> inline logical_data(backend_ctx_untyped ctx, ::std::shared_ptr<U> instance, data_place dp)

Constructor.

Template Parameters

U – Backend type

Parameters

ctx – Backend context
instance – Reference instance used for initializing this logical data
dp – Data place
data_prereq –
