NumBytes specifies the number of bytesto copy and must be evenly divisible by the array element size.Parameters:dptr - Destination device pointerhSrc - Source arraySrcOffset - Offset of source arrayNumBytes - Size of memory copy in bytesReturns:Note:CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED, CUDA_-ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_VALUESee also:Note that this function may also return error codes from previous, asynchronous launches.cuArray3DCreate, cuArray3DGetDescriptor, cuArrayCreate, cuArrayDestroy, cuArrayGetDescriptor, cuMemAlloc,cuMemAllocHost, cuMemAllocPitch, cuMemcpy2D, cuMemcpy2DAsync, cuMemcpy2DUnaligned,cuMemcpy3D, cuMemcpy3DAsync, cuMemcpyAtoA, cuMemcpyAtoH, cuMemcpyAtoHAsync, cuMemcpy-DtoA, cuMemcpyDtoD, cuMemcpyDtoH, cuMemcpyDtoHAsync, cuMemcpyHtoA, cuMemcpyHtoAAsync,cuMemcpyHtoD, cuMemcpyHtoDAsync, cuMemFree, cuMemFreeHost, cuMemGetAddressRange, cuMemGet-Info, cuMemHostAlloc, cuMemHostGetDevicePointer, cuMemsetD2D8, cuMemsetD2D16, cuMemsetD2D32,cuMemsetD8, cuMemsetD16, cuMemsetD323.25.2.16 CUresult cuMemcpyAtoH (void ∗ pDst, CUarray hSrc, unsigned int srcOffset, unsigned int bytes)Copies from one 1D CUDA array to host memory. pDst specifies the base pointer of the destination. hSrc andsrcOffset specify the CUDA array handle and starting index of the source data. bytes specifies the number ofbytes to copy.Parameters:pDst - Destination device pointerhSrc - Source arraysrcOffset - Offset of source arrayGenerated on Wed Apr 1 16:11:42 2009 for NVIDIA CUDA Library by Doxygen
3.25 Memory Management 149bytes - Size of memory copy in bytesReturns:Note:CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED, CUDA_-ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_VALUESee also:Note that this function may also return error codes from previous, asynchronous launches.cuArray3DCreate, cuArray3DGetDescriptor, cuArrayCreate, cuArrayDestroy, cuArrayGetDescriptor, cuMemAlloc,cuMemAllocHost, cuMemAllocPitch, cuMemcpy2D, cuMemcpy2DAsync, cuMemcpy2DUnaligned,cuMemcpy3D, cuMemcpy3DAsync, cuMemcpyAtoA, cuMemcpyAtoD, cuMemcpyAtoHAsync, cuMemcpy-DtoA, cuMemcpyDtoD, cuMemcpyDtoH, cuMemcpyDtoHAsync, cuMemcpyHtoA, cuMemcpyHtoAAsync,cuMemcpyHtoD, cuMemcpyHtoDAsync, cuMemFree, cuMemFreeHost, cuMemGetAddressRange, cuMemGet-Info, cuMemHostAlloc, cuMemHostGetDevicePointer, cuMemsetD2D8, cuMemsetD2D16, cuMemsetD2D32,cuMemsetD8, cuMemsetD16, cuMemsetD323.25.2.17 CUresult cuMemcpyAtoHAsync (void ∗ pDst, CUarray hSrc, unsigned int srcOffset, unsigned intbytes, CUstream hStream)Copies from one 1D CUDA array to host memory. pDst specifies the base pointer of the destination. hSrc andsrcOffset specify the CUDA array handle and starting index of the source data. bytes specifies the number ofbytes to copy.cuMemcpyAtoHAsync() is asynchronous and can optionally be associated to a stream by passing a non-zero streamargument. It only works on page-locked host memory and returns an error if a pointer to pageable memory is passedas input.Parameters:pDst - Destination device pointerhSrc - Source arraysrcOffset - Offset of source arraybytes - Size of memory copy in byteshStream - Stream identifierReturns:Note:CUDA_SUCCESS, CUDA_ERROR_DEINITIALIZED, CUDA_ERROR_NOT_INITIALIZED, CUDA_-ERROR_INVALID_CONTEXT, CUDA_ERROR_INVALID_VALUESee also:Note that this function may also return error codes from previous, asynchronous launches.cuArray3DCreate, cuArray3DGetDescriptor, cuArrayCreate, cuArrayDestroy, cuArrayGetDescriptor, cuMemAlloc,cuMemAllocHost, cuMemAllocPitch, cuMemcpy2D, cuMemcpy2DAsync, cuMemcpy2DUnaligned,cuMemcpy3D, cuMemcpy3DAsync, cuMemcpyAtoA, cuMemcpyAtoD, cuMemcpyAtoH, cuMemcpyDtoA,cuMemcpyDtoD, cuMemcpyDtoH, cuMemcpyDtoHAsync, cuMemcpyHtoA, cuMemcpyHtoAAsync, cuMemcpyHtoD,cuMemcpyHtoDAsync, cuMemFree, cuMemFreeHost, cuMemGetAddressRange, cuMemGet-Info, cuMemHostAlloc, cuMemHostGetDevicePointer, cuMemsetD2D8, cuMemsetD2D16, cuMemsetD2D32,cuMemsetD8, cuMemsetD16, cuMemsetD32Generated on Wed Apr 1 16:11:42 2009 for NVIDIA CUDA Library by Doxygen
