Compiling Viridithas

[Look]

Hi,

I have compiled Viridithas (commit 14837c6) and I compare it with official 14 release:

Problems:

• My compile deepens way slower

• PV moves mismatch

You have compiled it with the latest network? (as suggested by the readme)

Yes I used hyperstition-b400.nnue.zst and renamed it to viridithas.nnue.zst in my compile.

[Look]

By the way I used this compile command:

Code: Select all

RUSTFLAGS="-C target-cpu=x86-64" cargo b -r --features syzygy,bindgen

Note that target-cpu=native crashes the executable on this laptop. So I use the working x86-64 target.

[Look]

Adding opt-level = 3 to Cargo.toml file in [profile.release] seemingly helped neither.

[Guenther]

Well if I compile it here for my windows machine I get identical nodes/PVs as expected
to the official release (WINv3 in this case).

BUT both of yours are different than those ;)
That your own compilation shows a negative value at depth 2 is also a bad sign (-33).
(and before you ask depth 14 instead depth 15 ofc doesn't make a difference.
