Cinnamon 2.3

[geko]

Thanks Gabor, but the problem is on Hash not on book, I fixed it, can you do a test on version 2.3.2 ?

Hi Giuseppe,

It seems the problem has gone.

Hi Giuseppe,

What is the maximum size of HASH?
My system has 32 GB ram.
When I type uci from command line in linux :

uci
id name Cinnamon 2.3.2
id author Giuseppe Cannella
option name Hash type spin default 64 min 1 max 131071
...

So theoretically 131071 MB(128 GB).
Engine crashes immediately when using 2 GB hash or more on my system(Cutechess GUI).
Can you check this?
In version 2.2a engine works with 2 GB hash.

Kind regards,

Antonio

yes Antonio, the engine crashes if set 2 GB hash or more, I fixed it in version 2.3.3 at http://cinnamonchess.altervista.org
thanks

Hi all I'm the author, the gain in terms of elo is almost zero at least for Cinnamon, the advantage is that the code is shorter.

Hi, this is a very nice and interesting project.

I would like to add Cinnamon to my "list of unix engines", but there is still an error on MacOSX/clang, which is very easily solved by removing

Code: Select all

-static-libgcc

from the libs in Makefile.
If not this error appears:

Code: Select all

Hi OliverBr, I've used used gcc
make cinnamon64-modern-INTEL COMP=g++
anyway you can modify the Makefile as you wish.

Hi, of course I can modify the Makefile locally, but I think it should be modified in your repository, too.
So it compiles on MacOSX out-of-the-box, your Makefile does already have an own block for OSX

PS: I am creating a list with stable open source engines which compile easily on Linux and MacOSX.

Ok, I removed -static-libgcc and pushed on github

This is great. Your engine is now 100% Linux/MacOSX conform and stable. There are not many of them. I checked many hundreds and found only about 40 so far.

Version 2.3.3 forfeited time 27 times out of 320 games under Arena. Version 2.3 ran perfectly.

I intended to combine 2.3 and 2.3.3 results but now I am not sure what to do.
