Thank you, got it working now (but it's veryvery slow on the frigging mac).
What is the NPS of Igel? Also, what is the NPS of any other reference engine on that hardware?

Just 'bench' for both engines..

Code: Select all

m2/macos
igel: 287.539 NPS
stockfish-14.1: 1.397.015 NPS

i5-3210M/Debian
igel: 360.459 NPS
stockfish-14.1: 1.124.058 NPS
So...the translation takes time but it works :-) In Jims (thank you!) package were the files for this task:

Console input from bench doesn't work, then it closes.
Yes, the bench has to be the same for all flavours of igel compilation for the same version: e.g. Igel 3.6.0 correct bench must be 1202492. If it is not the same for some "custom compile" it means something is wrong and the produced binary is not actually Igel 3.6.0 in terms of playing strength.

To get the bench please run "igel.exe bench" in the command line.
My igel engines are:

23.09.2023 12:54 662.528 igel-2.6_old_cpu.exe
23.09.2023 12:54 656.896 igel-2.6_popcnt.exe

19.09.2024 08:48 48.569.344 igel-3.5.5_popcnt.exe
30.12.2024 19:18 48.784.896 igel-3.6.0_popcnt.exe

Is there a list of the expected bench values?

I had re-compile them and updated the download package. Same link.

Jim.
The package (which I redownloaded too) got updated files in the src-directory also. So this would explain the success in self-compiling (I thought about some local hickup first) ...
Git would've been helpful/more obvious here, but I won't complain. Thanks for the effort!

Hi chessica,

Absolutely. All bench values are found in the official igel source repo: https://github.com/vshcherbyna/igel/commits/master/

For example,

Igel 3.6.0 bench is 1202492

Igel 3.5.0 bench is 17628169

Igel 3.4.0 bench is 20709220

Igel 3.3.0 bench is 2703171

For the people with armbased macs, I modified the src-package (you'll need xcode for this to work) from Jim:
https://www.file-upload.net/download-15 ... 6.zip.html

type

Code: Select all

make pgo
in the src-directory.

Generated binary; maybe it calculates on your device:
