WebJan 23, 2024 · cudaMalloc ( (void**) & buff, width *height * sizeof (unsigned int)); That buff allocation isn't actually used anywhere in your code, but of course it will require another 32GB. So unless you are running on an A100 80GB GPU, this isn't going to work. The GPU I am testing on has 32GB, so if I delete the unnecessary allocation, and reduce the GPU ... WebMar 7, 2011 · The correct syntax is. Kernel <<< number of blocks, number of threads per block >>> (arguments) So if you are passing a number larger than 512 to the first launch parameter, you are not running more than 512 threads per block. If you pass a big number as the second parameter, the should be a kernel launch failure. memecs March 7, 2011, … horse floats for sale in nsw
