How are you able to specify which cpu you're compiling for? I can't get it to do anything except -march=native.

Unfortunately I cannot provide any information on this due to a lack of expertise. If you have
questions about compiling for special CPUs then I would refer you to the software and compiler
GURU Jim Ablett here in the forum. He was always able to help me in a very friendly and
competent manner.

Version 13.24 lost just 6.5 - 9.5 to Komodo Dragon in CCC. So not much progress lately?

[gabe_obsidian]

Yes, there was a lot of progress lately.
The event in CCC has a sample size of 16 games (or 8 pairs), which is extremely small, and you can't draw even a bit of a conclusion from it.
See leaderboards where obsidian was tested with thousands of games.

Good to hear and looking for version 14. BTW is it design decision, that Obsidian don't display current move in analysis?

Obsidian 13.23 is also playing in TCEC: https://tcec-chess.com/live.html
Currently, it's pitted against LCZero.

I would use -march=x86-64 instead of -march=native for the CPU architecture.
For the instruction set, i would use -msse4.2 for SSE4 and -mavx2 for AVX2.
