![]() ![]() But, presumably, the functions, cudaMalloc and cudaMemcpy, might be used wrongly. Specify grid and block size using Dim3 struct. However, after compilation and execution, the result in vector3 was not as expected. These variables are 3-component integer vectors of type dim3. NVCC is the only way to compile device (GPU) code for nvidia GPUs. A Sample Cuda C Code The above program adds the corresponding elements of two vectors X and Y, and stores the final result in a vector Z. This 4 lines of code will assign index to the thread so that they can match up with entries in output matrix. ![]() So i expect to see similar modifications for cuda codes for Tegra devices. In the sample code of the document, cudaMallocManaged used, instead of standard cudaMalloc, for unified memory allocation. The GPU processes columns of the image in parallel. ![]() To figure out what is copy unit of cudaMemcpy() and transport unit of cudaMalloc(), I wrote the below code, which adds two vectors,vector1 and vector2, and stores result into vector3. Hence checking Cuda for Tegra, applications notes, DA-06762-001v10.2, page 7 sample code. This code sample implements a Gaussian blur using Deriche's recursive method: outputs of the filter as well as the previous inputs. ![]()
