Seems you are right about the compiles, Minic 3.13 is half way and doing fine.

Thanks for testing.

Important bug fix release : Minic 3.13
Available here : https://github.com/tryingsomestuff/Mini ... ter/Minic3

This release is fixing a speed issue for non-AVX2 build of Minic since version 3.07.
The expected strength increase for SSE and AVX system is major.

Some little improvements of the engine also make this release a little better for AVX2 system.

Thanks for this release as I my testing also show genuine gains. I have an Intel Sandybridge and was beginning to wonder whether it was just me who saw no gains and even some regression between 3.07 and 3.13.

May I suggest either removing the buggy builds on github or at least make clear on the 3.13 builds that this is an important fix and should avoid using the non-AVX2 builds from 3.07 until at least 3.13?

You got this right, non-AVX2 build from 3.07 to 3.12 are too slow.
So also you confirm that 3.13 is way stronger on sandybridge ?

I probably won't remove previous releases as most often people are using the last one and because they were tested.

My test run not completed yet but currently +47 ELO from Minic 3.04 Noisy Notch (nehalem)

I got the following speed with a go depth 20 command on my Ryzen 7 1700 (1 thread, all defaults)

Zen v2 is faster, even in my zen 1 processor.

Speed looks ok, thanks for the test.

Gcc -march option documentation for Zen v1 and v2 reads almost the same

Code: Select all

‘znver1’
    AMD Family 17h core based CPUs with x86-64 instruction set support. (This supersets BMI, BMI2, F16C, FMA, FSGSBASE, AVX, AVX2, ADCX, RDSEED, MWAITX, SHA, CLZERO, AES, PCLMUL, CX16, MOVBE, MMX, SSE, SSE2, SSE3, SSE4A, SSSE3, SSE4.1, SSE4.2, ABM, XSAVEC, XSAVES, CLFLUSHOPT, POPCNT, and 64-bit instruction set extensions.)

‘znver2’
    AMD Family 17h core based CPUs with x86-64 instruction set support. (This supersets BMI, BMI2, CLWB, F16C, FMA, FSGSBASE, AVX, AVX2, ADCX, RDSEED, MWAITX, SHA, CLZERO, AES, PCLMUL, CX16, MOVBE, MMX, SSE, SSE2, SSE3, SSE4A, SSSE3, SSE4.1, SSE4.2, ABM, XSAVEC, XSAVES, CLFLUSHOPT, POPCNT, RDPID, WBNOINVD, and 64-bit instruction set extensions.)

Moreover in Minic I don't use PEXT for zen v1, zen v2 and bd v4.

So as soon as you have AVX2 and FMA available performances shall be quite good. Next step is to have a good BMI2 of course (so skylake or zenv3 ...).

As you probably know it is really not recommanded to use executable compiled for a newer architecture than the one of your CPU because you can run for an illegal instruction. In your case it seems only CLWB, RDPID, and WBNOINVD may fail it seems but anyway.

If I were you i'll stick to the binary that fits your architecture but please note that only Intel builds on linux are made using PGO, not the AMD ones and not for windows builds.

Hi everyone,

Minic 3.14 is released with a new embedded net named "Nucleated Neurulation". This net was train only on FRC positions (2B data from previous net selfplay). Minic 3.14 is +30Elo better than 3.13 at selfplay but this does not always seem to hold versus more various opponents.

Minic 3.14 comes with some bug fixes and some additionnal features. Also maybe i forgot to advertise about the armegeddon feature already present in previous versions.
[Troll but real ...]
Minic now has a "Bongcloud" option that forces it to make a king move in early game stage (if not already castled thanks to book moves). Really usefull stuff ...
[end of troll]

As always, the net itself can be found here (but is embedded anyway) : https://github.com/tryingsomestuff/NNUE-Nets
And the binaries are there : https://github.com/tryingsomestuff/Mini ... d19/Minic3

I'm currently working on bigger net architecture and training process.

Have fun.
