New Mac Compiles (+ Website)

Post by JuLieN » Mon Aug 26, 2013 7:17 pm

I compiled a few more chess engines for Mac (x86_64 binaries). I also built up a quick and dirty website for all those engines, as it's still better than the ftp directory I had before. It will get better with time.

New engines :
• Crafty 23.6
• Eia 0.1
• Octochess r5178
• Sting SF 130131
• StockFish 2.3.1
• Vice 1.0

(Yes, I know that Stockfish and Sting SF are a bit old now, but I had them sleeping on my harddisk, so... ;) )

Website : http://julien.marcel.free.fr/macchess/

If you know some engines for Mac that I forgot to add to my list please do not hesitate to contact me. If some more engines could be compiled (or you have compiled them and I didn't) please contact me as well. :)

Thanks Julien for your Mac support!

BTW, Octochess 5178 compiles well with gcc 4.7.3 (macports) and -flto. So it could be a gcc 4.8.1 compiler issue.

Flto gives about 17% speedup on my old Mac.

gcc 4.7 with -flto:

Code: Select all

./octochess5178-g47 --threads 1 --depth 18 --memory 1 --moves 1 auto
Octochess
..
..
Runtime: 83325 ms 

Node stats:
  Total:                  51954300
  Full-width:             17456911
  Quiescence:             34497389
  Nodes per second:         623519
  Time per node:           1603 ns
gcc 4.8 without -flto:

Code: Select all

./octochess5178-g48 --threads 1 --depth 18 --memory 1 --moves 1 auto
Octochess
..
..
Runtime: 97548 ms 

Node stats:
  Total:                  51954300
  Full-width:             17456911
  Quiescence:             34497389
  Nodes per second:         532608
  Time per node:           1877 ns

Thanks for the info, Max. :)

Pity they let such a big bug make it to the release. As I'm on holidays I don't think I can update my compiler through my mobile's tethering. :lol:

I'll soon release a (big) handful of new compiles though.
