Chess Engine Ratings on Raspberry Pi 2

[DJ Dekker]

Just for fun I conducted a couple of engine tournaments in Scid vs. PC 4.15 on Raspberry Pi 2. The results, based on an average of 450 games per engine, give an indication of relative engine strength.

An approximate Elo rating --without any pretense of scientific accuracy-- was calculated with Miguel Ballicora's ordo program and is shown here in parentheses.

1. Stockfish 7 (2972)
   
2. Senpai 1.0 (2652)
   
3. Texel 1.05 (2645)
   
4. Hakkapeliitta 3 (2596)
   
5. Arasan 18.2 (2479)
   
6. Toga II 1.3.1 (2465)
   
7. Donna 4.0 (2245)
   
8. GreKo 2015 (2226)
   
9. Maverick 0.6 (2071)
   
10. Zurichess Glarus (2043)
    
11. Floyd 0.7 (1962)
12. Sayuri 2015.12.31 (1814)
13. Cinnamon 1.2b (1724)

Very nicely done and very interesting. Thanks for sharing.

Gavon chess system running on a Pi 2 tested Stockfish 6 to a bit over 3000 Elo. Quite impressive for such a nice little machine as the Pi, I think.

Did you compile all those engines for the Pi?

Hi Torben,

Yes, I built those engines on my Raspberry Pi 2 except for two:
- Toga, which comes with Scid vs. PC;
- Maverick, which can be downloaded as a binary that happens to run on RPi2.

Still trying to move on to a more recent and better optimized OS than Raspbian Wheezy. If only this Bluetooth autoconnect would work in Raspbian Jessie or Ubuntu MATE...

Greetings,
DJ

Hi DJ

Ok, thanks! I will try some of those engines.

Good luck on upgrading PicoChess to a newer OS - that would be awesome.

Greetings

Torben

Do you have a ubuntu mate image? What version of bluez is installed by default on ubuntu mate, if it's 4.x, then I know how to mAke bluetooth auto work.

Hi Shiv,

I have a working Ubuntu MATE 15.10.1 installation. Picochess runs fine, except for the Bluetooth autoconnect. Ubuntu 15 has BlueZ 5 installed, not BlueZ 4. This is exactly the problem... how to get Bluetooth to autoconnect with an SPP connection upon boot using BlueZ 5, which has bluetoothctl instead of bluez-simple-agent and seems to handle rfcomm.conf differently. I wish there were some sites with BlueZ 5 documentation.

I will be glad to try to make it work with ubuntu mate. I think I have an idea of how to make it work with ubuntu.

If u have time to upload it, I can take a look. I am out of town till Feb 2 (fyi).

hello, I found this from the thread at the pi-forum.

 

elo 2900 on the Rpi2B for stockfish 7

elo 3400 is given in the lists for a 64-bit PC with 4 cores

I found an increase of ~100 elo for 4 cores vs. 1

 

so the pi is 4^4=256 times slower than one of those

PCs with 64-bit, where they test this ?
