M1 Apple Silicon for Chess?

[acepoint_de]

I have tried via command line (it says: illegal hardware instruction). Where I'm wrong?

No idea. I installed homebrew twice, one in /usr/local for intel and one in /opt/homebrew, according to the suggestions in the web. I made an alias ibrew for the intel stuff. I installed lc0 with

Code: Select all

brew install lc0

copied an renamed binary and net into my engine folder. Same for two different stockfish engines just for some small research.

stockfish: Mach-O 64-bit executable x86_64

say in your case?

And how to use it in a chess GUI?

Like every other uci engine.

Lol when do people buy a laptop just to play chess. Why does my company or Google give every software engineer a MacBook instead of an ASUS?

To be fair, I think it's fine to prefer other laptops over a MacBook when it was Intel, but now, I dont see why anyone would buy a non MacBook laptop anymore, unless you must use some software just available on Windows. It's just that much better.

And if you want beefy GPUs, why not just go for a desktop..

You seems to be just a typical fanboy of a rotten apple. You see, there are ppl that hate closed "ecosystems", don't like macOS, prefer that most of the money they invest in laptop goes into hardware and not the logo and "slick" design, hate its thermal management, prefer to have real ports instead of dragging a bunch of "accessories", prefer to have flexibility to chose their own software instead of everything being set up how Apple thinks it's best for the sheep, etc. etc.

Haha calling me Apple sheep, I previously worked at AMD, even worked on the newest Cezanne APU drivers, and I'm still rooting for AMD; but for now I don't see anything laptop that can actually compete with the newest MacBooks.

If you choose to be blind to benchmarks and reviews, that's your personal issues.

You are a fanboy coz you are totally delusional about the performance of your favorite brand. Basically iSheep only look at Geekbench that is the least relevant and crappy benchmark that exists and the one where Apple pumps its performance.
Ryzen 5000 mobile top range CPUs (like 5700G or 5980HS) are better single core than M1 and in multicore are 50-80% stronger. M1 graphics/AI performance is a joke. In chess (SF-NNUE) gap is 30% single core and 120% multicore in favor of mobile AMD.
Some software just available on Windows you say? You don't even seem to be aware of how large laptop gaming community is. Good luck running any game on M1.
And all this M1 performance comes from advanced technology node, not superior architecture and other marketing BS Apple is selling to its iSheep.
When AMD moves in next gen to 5nm high-end performance gap is only gonna increase.

Ah let the hate flow thru you.

If you just choose to ignore bunch of other standard benchmarks like SPEC, then you do you. In SPEC It's almost on par with 5950X in single thread ffs! And attacking Geekbench is probably one of Apple haters' favorite pasttime, even though most of the arguments are completely unfounded. The node advantage is also not that great of an argument, given that a better process doesn't really give that much in terms of single thread. The reason I care mostly about single thread is that adding more cores is easy, but having good core design is much harder.

Are you seriously attacking the graphics/AI capability of a chip found in an ultrabook? Once Apple chip gets scaled up, I'd be very surprised if it doesn't beat out anything else in the market, yes, even in SF-NNUE.

To be fair, yes, if you play heavy PC games, you'd be better served not getting a mac, but if I played games, I'd rather just get a desktop at that point.

I'm with Milos, will never buy an Apple product, I despise that company.

I have done exactly the same. Now I try to move it on a different folder (I have launched it also from the compiled folder) . I use BanksiaGui and Stockfish M1 works fine.

Did you try running lc0 at the command line using the commands uci and go infinite?

Yeah, of course. For me the tuning fails:

Code: Select all

Selected device: Apple M1
with OpenCL 1.2 capability.
Started OpenCL SGEMM tuner with batch size 16.
Will try 578 valid configurations.
Failed to find a working configuration.
Check your OpenCL drivers.
Unhandled exception: Tuner failed to find working configuration.

This is with current git though. Maybe they broke it.

Ah, it's the network that is the problem. I guess it's too big.

Hmm, no, the homebrew version works with everything. So this is a mystery: if I compile the exact same version homebrew uses, OpenCL doesn't work. I looked at the homebrew formula and there's nothing special in there. WTF.

I then tried to brew install -s lc0 (i.e. compile from source), and the resulting exe crashed the M1 graphics driver.

It seems to work if I specify -Dgtest=false to the meson build. Strange. Really strange.

I've managed to configure LC0 on BanksiaGui. It starts, but makes silly moves like: 1.e4-e6 2.Nf3-Ke7 ???? I think the NN is the cause.

Please, continue to try to fix it. I'm sure that Silicon M1 with neural network INSIDE will be the best for chess engines. Already with Rosetta 2 converted engines it is very very fast! I will follow your experiments
