WebFeb 6, 2013 · cudaMallocPitch () ensure that the starting address of each row in the 2-D array (row-major) is a multiple of 2^N (N is 7~10 depending on the compute capability). Whether the accesss is more efficient depends on not only the data alignment but also your compute capability, global mem access manner and sometimes the cache configuration. WebSep 29, 2009 · From the Dr. Dobb’s article 13 on CUDA: “The CUDA Toolkit 2.2 introduced the ability to write to 2D textures bound to pitch linear memory on the GPU that has a texture bound to it. In other words, the data within the texture can be updated within a kernel running on the GPU.” Can anyone point me to an example of how to do this or provide one?
