Re: Where to enter/read position into hash table in perft?

You can see that the hash probe causes an enormous slowdown in terms of nps. This is normal, and a good illustration of how expensive a memory access is. Your nps drops about a factor 2.5. So that single cach-line read for the hash probe took 1.5 times as much time as generating all moves!

Re: Advice on book building

Well, for starters you can make the Edit Book window a bit wider to get the buttons at the bottom in full view (although you already see all of them, and could use them this way). And move it to a screen location that is convenient for you, and where it does not cover the board. Perhaps shrink the b...

Re: Advice on book building

That's why programmers shouldn't design GUIs. What's funny is that when I needed to use a position on Winboard, it was faster to open the Shredder GUI and create the position there, then just copy the FEN, than having to deal with that extravaganza. Should have been a sure sign you were doing somet...

Re: Advice on book building

The only "book" item I can see is Engine - Book and when I click nothing happens. There is Edit - Edit Book . The Engine - Book menu item is for requesting the engine's own book. But not many engines do support an own book anymore, these days. So how does one create a new book from scratch? The Win...

Re: Advice on book building

There's no chance I could have ever found about that if you didn't tell me. Well, this also has already been solved in the development version: this gives you the palette board first time you click the clock, together with the message "Click again to clear more". If you then click again, it clears ...

Re: Advice on book building

I would like the book editor used short algebraic notation like in Scid, it's a bit confusing with only these square letters and numbers. Oh, that's true. WinBoard 4.8 still does that. The WinBoard 4.9 or the development version ( http://hgm.nubati.net/WinBoard-AA.zip ) already display the moves in...

Re: Advice on book building

Here's just one example of the kind of stuff you'd need to learn to use Winboard: To set up a position, you do Mode > Edit Position. You'll see a message that tells you that to clear the board you need to click on the clocks, even though you won't see any clocks. It turns out the "White / Black" ba...

Re: Advice on book building

I want to try this book editing in WinBoard for editing my own book. Where exactly can I change the book to edit? Where can I find this Common Engine Settings dialog? In the Engine main menu ('Common Settings'). The book name should go into the text entry after 'Use book:', which also has a browse ...

Re: Advice on book building

Is there a help file on this? Not really, but it doesn't seem rocket science. What I wrote above pretty much describes all there is to it. I downloaded it and it wasn't immediately obvious. The window was tiny for some strange reason as well and when I dragged it bigger it disconnected from the oth...
