54 Module Documentation IMPORTANT NOTE: Copies with kind == cudaMemcpyDeviceToDevice are asynchronous with respect to the host, but never overlap with kernel execution. Parameters: symbol - Symbol destination on device src - Source memory address count - Size in bytes to copy offset - Offset from start of symbol in bytes kind - Type of transfer stream - Stream identifier Returns: Note: cudaSuccess, cudaErrorInvalidValue, cudaErrorInvalidSymbol, cudaErrorInvalidDevicePointer, cudaErrorInvalidMemcpyDirection See also: Note that this function may also return error codes from previous, asynchronous launches. cudaMemcpy, cudaMemcpy2D, cudaMemcpyToArray, cudaMemcpy2DToArray, cudaMemcpyFromArray, cudaMemcpy2DFromArray, cudaMemcpyArrayToArray, cudaMemcpy2DArrayToArray, cudaMemcpyToSymbol, cudaMemcpyFromSymbol, cudaMemcpyAsync, cudaMemcpy2DAsync, cudaMemcpyToArrayAsync, cudaMemcpy2DToArrayAsync, cudaMemcpyFromArrayAsync, cudaMemcpy2DFromArrayAsync, cudaMemcpyFromSymbolAsync 4.8.2.35 cudaError_t cudaMemGetInfo (size_t ∗ free, size_t ∗ total) Returns in ∗free and ∗total respectively, the free and total amount of memory available for allocation by the device in bytes. Parameters: free - Returned free memory in bytes total - Returned total memory in bytes Returns: Note: cudaSuccess, cudaErrorInitializationError, cudaErrorPriorLaunchFailure, cudaErrorInvalidValue Note that this function may also return error codes from previous, asynchronous launches. 4.8.2.36 cudaError_t cudaMemset (void ∗ devPtr, int value, size_t count) Fills the first count bytes of the memory area pointed to by devPtr with the constant byte value value. Parameters: devPtr - Pointer to device memory Generated for NVIDIA CUDA Library by Doxygen
4.8 Memory Management 55 value - Value to set for each byte of specified memory count - Size in bytes to set Returns: cudaSuccess, cudaErrorInvalidValue, cudaErrorInvalidDevicePointer Note: Note that this function may also return error codes from previous, asynchronous launches. See also: cudaMemset2D, cudaMemset3D 4.8.2.37 cudaError_t cudaMemset2D (void ∗ devPtr, size_t pitch, int value, size_t width, size_t height) Sets to the specified value value a matrix (height rows of width bytes each) pointed to by dstPtr. pitch is the width in bytes of the 2D array pointed to by dstPtr, including any padding added to the end of each row. This function performs fastest when the pitch is one that has been passed back by cudaMallocPitch(). Parameters: devPtr - Pointer to 2D device memory pitch - Pitch in bytes of 2D device memory value - Value to set for each byte of specified memory width - Width of matrix set (columns in bytes) height - Height of matrix set (rows) Returns: Note: See also: cudaSuccess, cudaErrorInvalidValue, cudaErrorInvalidDevicePointer Note that this function may also return error codes from previous, asynchronous launches. cudaMemset, cudaMemset3D 4.8.2.38 cudaError_t cudaMemset3D (struct cudaPitchedPtr pitchedDevPtr, int value, struct cudaExtent extent) Initializes each element of a 3D array to the specified value value. The object to initialize is defined by pitchedDevPtr. The pitch field of pitchedDevPtr is the width in memory in bytes of the 3D array pointed to by pitchedDevPtr, including any padding added to the end of each row. The xsize field specifies the logical width of each row in bytes, while the ysize field specifies the height of each 2D slice in rows. The extents of the initialized region are specified as a width in bytes, a height in rows, and a depth in slices. Extents with width greater than or equal to the xsize of pitchedDevPtr may perform significantly faster than extents narrower than the xsize. Secondarily, extents with height equal to the ysize of pitchedDevPtr will perform faster than when the height is shorter than the ysize. This function performs fastest when the pitchedDevPtr has been allocated by cudaMalloc3D(). Generated for NVIDIA CUDA Library by Doxygen
