ensure_cpu_up_to_date()

template<typename T>

void etl::gpu_memory_handler< T >::ensure_cpu_up_to_date ( [[maybe_unused] ] const T *  cpu_memory, [[maybe_unused] ] size_t  etl_size  ) const

inline

Copy back from the GPU to the expression memory if necessary.

Parameters

etl_size	The size of the memory

ensure_gpu_allocated()

template<typename T>

void etl::gpu_memory_handler< T >::ensure_gpu_allocated ( [[maybe_unused] ] size_t  etl_size ) const

inline

Ensures that the GPU memory is allocated and that the GPU memory is up to date (to undefined value).

Parameters

etl_size

The size of the memory

ensure_gpu_up_to_date()

template<typename T>

void etl::gpu_memory_handler< T >::ensure_gpu_up_to_date ( [[maybe_unused] ] const T *  cpu_memory, [[maybe_unused] ] size_t  etl_size  ) const

inline

Allocate memory on the GPU for the expression and copy the values into the GPU.

Parameters

cpu_memory	Pointer to CPU memory
etl_size	The size of the memory

gpu_copy_from()

template<typename T>

void etl::gpu_memory_handler< T >::gpu_copy_from ( [[maybe_unused] ] const T *  gpu_memory, [[maybe_unused] ] size_t  etl_size  ) const

inline

Copy from GPU to GPU.

Parameters

gpu_memory	Pointer to CPU memory

gpu_memory()

template<typename T>

T* etl::gpu_memory_handler< T >::gpu_memory ( ) const

inlinenoexcept

Return GPU memory of this expression, if any.

Returns

a pointer to the GPU memory or nullptr if not allocated in GPU.

is_cpu_up_to_date()

template<typename T>

bool etl::gpu_memory_handler< T >::is_cpu_up_to_date ( ) const

inlinenoexcept

Indicates if the CPU memory is up to date.

Returns

true if the CPU memory is up to date, false otherwise.

is_gpu_up_to_date()

template<typename T>

bool etl::gpu_memory_handler< T >::is_gpu_up_to_date ( ) const

inlinenoexcept

Indicates if the GPU memory is up to date.

Returns

true if the GPU memory is up to date, false otherwise.
