Pro Deo was using 128 MB. When I made it 32 MB >(the same was used by Shredder 8), Shredder 8 started beating Pro Deo. So, >please check for hash size. > >P L Patodia The difference between 128 MB and 32 MB is very small(probably only 12-14 elo) I guess that it is possible that Shredder was slowed down significantly during the match. I think that it is better not to use more than 1/8 of the available ram for engines. I remember that Igor inspite of having 256 mbytes does not use 64 mbytes per engine in the infinite loop because there are problems with it when one engine is slowed down significantly. Uri
