And what nps do we think it gets on modern hardware?

Seems like it's not threaded, but the original was.

Ahh thank you, I was so exciting by this wonderful thing I totally missed that. So even with Dann's 100K nps above, it looks like on modern hardware we're hitting 20x faster.

[edit, although if this is CrayBlitz from 1990, presumably it was more than 100K - perhaps double that. So 10x faster.]

Jim Ablett wrote: Wed Mar 20, 2024 8:48 pmThe Fortran src files have been converted to C src files but I haven't been able to compile a working executable from it so far. Once I get over that stage then it should be straightforward to add winboard or uci interface to it.

I cant do it in Fortran, I don't know the language :cry:

That's OK, because you don't need to! Both Gemini and ChatGPT give a useful response to the prompt, "Write FORTRAN code to send a command to the Windows command prompt."

You might be reviving one of the great programs of old - but you don't have to live with the constraints of the old times! :)

You can also ask questions like, "What does this FORTRAN code do?", and then paste 100 lines or so of FORTRAN code.
Writing is the antidote to confusion.
It's not "how smart you are", it's "how are you smart".
Your brain doesn't work the way you want, so train it!
