Q&A

  1. Can the PyTorch profiler be used without any specific things to take into account, see link?

    Answer:

    That is correct. Let us know if you come across any problems.

  2. Could you give a rough estimate on the overhead in terms of percentage?

    Answer

    • Generally very low, but can be high in unusual cases.
    • Hard to say exactly what the overhead is, depends usually on the ammount of data being collected. A code with a lot of smaller chunks of GPU activity are usually more pronoe to show more overhead.
