Function Documentation

SanitizerResult SANITIZERAPI sanitizerAlloc	(	void **	devPtr,
		size_t	size
	)

Equivalent of cudaMalloc that can be called within a callback function.

Note:

Thread-safety: this function is thread safe.

Parameters:

	devPtr	Pointer to allocated device memory
	size	Allocation size in bytes

SanitizerResult SANITIZERAPI sanitizerAllocEx	(	void **	devPtr,
		size_t	size,
		Sanitizer_MemoryData *	memoryData
	)

Equivalent of cudaMalloc that can be called within a callback function.

Note:

Thread-safety: this function is thread safe.

Parameters:

	devPtr	Pointer to allocated device memory
	size	Allocation size in bytes
	memoryData	Extra parameters for the memory allocation

SanitizerResult SANITIZERAPI sanitizerFree

(

void *

devPtr

)

Equivalent of cudaFree that can be called within a callback function.

Note:

Thread-safety: this function is thread safe.

Parameters:

devPtr

Device pointer to memory to free

SanitizerResult SANITIZERAPI sanitizerFreeEx	(	void *	devPtr,
		Sanitizer_MemoryData *	memoryData
	)

Equivalent of cudaFree that can be called within a callback function.

Note:

Thread-safety: this function is thread safe.

Parameters:

	devPtr	Device pointer to memory to free
	memoryData	Extra parameters for the memory free

SanitizerResult SANITIZERAPI sanitizerMemcpyDeviceToHost	(	void *	dst,
		void *	src,
		size_t	count,
		CUstream	stream
	)

Equivalent of cudaMemcpy that can be called within a callback function. The function will return once the copy has completed.

Note:

Thread-safety: this function is thread safe.

Parameters:

	dst	Destination memory address
	src	Source memory address
	count	Size in bytes to copy
	stream	Stream identifier

SanitizerResult SANITIZERAPI sanitizerMemcpyDeviceToHostEx	(	void *	dst,
		void *	src,
		size_t	count,
		CUstream	stream,
		Sanitizer_MemoryData *	memoryData
	)

Equivalent of cudaMemcpy that can be called within a callback function. The function will return once the copy has completed.

Note:

Thread-safety: this function is thread safe.

Parameters:

	dst	Destination memory address
	src	Source memory address
	count	Size in bytes to copy
	stream	Stream identifier
	memoryData	Extra parameters for the data copy

SanitizerResult SANITIZERAPI sanitizerMemcpyHostToDeviceAsync	(	void *	dst,
		void *	src,
		size_t	count,
		CUstream	stream
	)

Equivalent of cudaMemcpyAsync that can be called within a callback function. The function will return once the pageable buffer has been copied to the staging memory for DMA transfer to device memory, but the DMA to final destination may not have completed.

Note:

Thread-safety: this function is thread safe.

Parameters:

	dst	Destination memory address
	src	Source memory address
	count	Size in bytes to copy
	stream	Stream identifier

SanitizerResult SANITIZERAPI sanitizerMemcpyHostToDeviceAsyncEx	(	void *	dst,
		void *	src,
		size_t	count,
		CUstream	stream,
		Sanitizer_MemoryData *	memoryData
	)

Equivalent of cudaMemcpyAsync that can be called within a callback function. The function will return once the pageable buffer has been copied to the staging memory for DMA transfer to device memory, but the DMA to final destination may not have completed.

Note:

Thread-safety: this function is thread safe.

Parameters:

	dst	Destination memory address
	src	Source memory address
	count	Size in bytes to copy
	stream	Stream identifier
	memoryData	Extra parameters for the data copy

SanitizerResult SANITIZERAPI sanitizerMemset	(	void *	devPtr,
		int	value,
		size_t	count,
		CUstream	stream
	)

Equivalent of cudaMemset that can be called within a callback function.

Note:

Thread-safety: this function is thread safe.

Parameters:

	value	value to set for each byte of specified memory
	count	Size in bytes to set
	stream	Stream identifier

SanitizerResult SANITIZERAPI sanitizerMemsetEx	(	void *	devPtr,
		int	value,
		size_t	count,
		CUstream	stream,
		Sanitizer_MemoryData *	memoryData
	)

Equivalent of cudaMemset that can be called within a callback function.

Note:

Thread-safety: this function is thread safe.

Parameters:

	devPtr	Pointer to device memory
	value	value to set for each byte of specified memory
	count	Size in bytes to set
	stream	Stream identifier
