help me in the csvn tournament

Post by flok » Fri Nov 14, 2014 8:59 am

Hi people,

This weekend I'll be participating in the CSVN computerchess tournament.
For that I created a chess program that can scale almost unlimited both vertically and horizontally.
And you can help!
Download and run the program from http://www.vanheusden.com/QB/ and your computer will help finding the best move.
If you size the terminal in which it runs to 132x25 then you can see what it (your local instance) comes up with.

Thanks in advance!

There are separate 32-bit and 64-bit compiles for Linux, but just one for Windows. Is that 64-bit ?

Does it just use one core ?

Hi,

It uses hardly any memory so 64b would be a disadvantage (longer pointers, more cache pressure, etc).
It uses all cores available.

I don't remember but if 2 times faster means 70 ELO than my chess engine should be running at least 32000 times faster to beat Stockfish. So you need many people to help you. Can your server handle that many connections.

Bottleneck is the internet connection: 5Mb up so that is about 500 connections.

Thanks, I'll contribute either a 6-core or 8-core AMD Windows box.

Hi Folkert,

I've fired it up on my AMD FX-4354 4.2GHz 4 core Windows box. I'll leave it there now and over the weekend...

Good luck!

PS: How do we follow your progress?

Colin,

The csvn announcement said that they'll use special boards that do a live publish of what is moved. So I think there will be a link to that on www.csvn.nl

What's a "playout"?
