Hi @eqy, thank you. Yes, the script does run for a long time, so I can try those commands you mentioned. But what I really wanted to check is whether this simple python code gets converted to NV PTX code to run on the GPU automatically? Since I am doing the multiply accumulate manually and until I came across a tutorial, I imagined I would have to write CUDA C++ code to use the GPU. That’s why I wanted to ask and double check.
