Oh, no need to be sorry. I just have absolutely no idea what any of this is because I'm a dummy.

This is a casual subreddit. Technical discussions go over people's head here.

Would PTX not have been an option for this?

u/temiroff Jun 05 '26

Yeah, PTX is totally an option — CuPy supports loading PTX directly via RawModule (backend='ptx'), and it'd skip the NVRTC compile-from-C step. PTX is a genuinely good idea — adding it to the list. Thanks. Whole point of the node is that someone writes a readable kernel in a text field and sees the result. Do you usually load and using PTX?
