Let me add a couple of notes...

If you use a newer xboard/winboard, crafty supports the new "cores" and "memory" GUI->engine commands. But with some exceptions.

If you want to use the winboard/xboard menu to set memory (which is combined hash + pawn hash) or number of threads, then you must _not_ use the mt=n command, nor set the hash=n or phash=n options in your .craftyrc/crafty.rc configuration file. If you specify hash sizes or max threads there, crafty will not use the winboard cores/memory commands. So make certain that if you want to use the new winboard options, you remove those lines from the crafty config file.

If you want to use the memory option from winboard/xboard, you specify the size in megabytes. You need to give some thought to this number. The regular hash table must be a power of 2. Ditto for the pawn hash. A good setting would be 288, which would be interpreted as follows:

1. Crafty finds the largest power of two value in that number (which is 256m above) and uses that for the primary hash.

2. It then subtracts 256m from the above value, and then finds the largest power of two remaining and uses that as the pawn hash size. Any extra memory is unused.

Not very elegant, but I could not think of a better solution. Probably is easier to use the .craftyrc file to set those options, which will make the xboard settings irrelevant.


I actually just realized that you _must_ set the engine parameters in Winboard no matter what. The Crafty.rc file isn't being used at all. If you try setting the Winboard parameters to nothing, it of course defaults to the last used.



That's not the case with xboard. And, in fact, unless you put the crafty.rc file in the wrong place (it should be in the -fd directory) I don't see how crafty could not use that file. It certainly does here. But that's xboard and not winboard.


Quote:


I have set Winboard to use max 1024 for HASH, but have 2048 in my rc file. Winboard is controlling the hash at a max of 1024.

Either way, Winboard is controlling the settings, not Crafty at all.

I am not sure I like this. Those are supposed to be polyglot options, not options for _all_ engines, including Winboard engines.
