Re: Tucano 7.00 Release - SMP version

If you want to give another try, use the following below: [OPTIONS] Program=tucano_w64.exe InitString=option Threads=8\noption Hash=512\n This setup should send the threads and hash information dir...

Hi Guenther,

Hello, Tucano 7.00 is available for download at https://sites.google.com/site/tucanochess This is the parallel search version (shared hash table implementation).
