Detailed Description

Copy operation to move data between two GPU addresses.

Constructor & Destructor Documentation

◆ CudaCopyOperation()

umpire::op::CudaCopyOperation::CudaCopyOperation ( cudaMemcpyKind kind )

Member Function Documentation

◆ transform()

void umpire::op::CudaCopyOperation::transform	(	void *	src_ptr,
		void **	dst_ptr,
		umpire::util::AllocationRecord *	src_allocation,
		umpire::util::AllocationRecord *	dst_allocation,
		std::size_t	length
	)

virtual

Transform length bytes of memory from src_ptr to dst_ptr.

Uses cudaMemcpy to move data when both src_ptr and dst_ptr are on NVIDIA GPUs.

Parameters

src_ptr	Pointer to source memory location.
dst_ptr	Pointer to destinatino memory location.
src_allocation	AllocationRecord of source.
dst_allocation	AllocationRecord of destination.
length	Number of bytes to transform.

Exceptions

util::runtime_error

Reimplemented from umpire::op::MemoryOperation.

◆ apply()

void umpire::op::MemoryOperation::apply	(	void *	src_ptr,
		util::AllocationRecord *	src_allocation,
		int	val,
		std::size_t	length
	)

virtualinherited

Apply val to the first length bytes of src_ptr.

Parameters

src_ptr	Pointer to source memory location.
src_allocation	AllocationRecord of source.
val	Value to apply.
length	Number of bytes to modify.
