Re: Houdini 1.5 from 2011 has a surprise

Update to the prior post. The memory optimizer finally finished. I had 89% free before it started and during the optimization process, it took free memory down well below half. Now that it is done, I have 90% free. So it appears it freed 1% of my memory during the defrag process. I could easily allo...

Re: Houdini 1.5 from 2011 has a surprise

I haven't noticed any fragmentation after some weeks large pages use. I see it all the time. If I want to use 100GB hash with large pages, I usually have to reboot. Dann, You may want to give this a try: https://www.wisecleaner.com/wise-memory-optimizer.html On my 64GB machine the optimization take...

Re: Can You activate large pages in Windows 10 Home?

I've never had home editions of Windows, but setting the large page options in win7 never worked for me unless I ran the engine as administrator. Just another stupid Microsoft thing to decrease system security. Give it a try. I have two win7 machines and run large pages on both (one pro and one ente...

Re: Can You activate large pages in Windows 10 Home?

Hmm may be too complicated for just 1-2% speedup. Unless You have superhardware. With a TT of several gigabytes, the speed up is more like 8-10%. However, you may need Windows 10 Pro to get full access to your own hardware (at least I was not able to make large pages work on Windows 7 Home). On old...

Re: Dragon by Komodo Chess

OK, I ran a test of a SF net from around the time of SF12 release (net 1705) running in Dragon vs. Dragon with its own embedded net. The SF net lost by 244 elo after 2200 bullet games. So it was still playing very strong chess, better than 99% of engines, but way below its true strength. So I guess...

Re: Dragon by Komodo Chess

Larry/Mark, in the Dragon UCI options it appears you can specify an nnue network. Do you use the same architecture as SF. Meaning, could I specify a SF network and have dragon work properly?

Re: MessChess

Well, AFAIK the Certabo team has already added MessChess to their board, but I don't know how well this works. It doesn't work well. From what I read in their forums, I get the impression there is a software board simulator that allows you to write code/test without a board, but I haven't looked in...

Re: MessChess

Franz, I am also very appreciative of your work. I used to own several of these computers, but all but one eventually died. It is amazing to still have them to play. Are you considering a direct interface to the Certabo boards? My wife bought me one for my birthday! She asked if I'd teach her to pla...

Re: Build tester issue

One other issue that can cause the new NNUE SF to not generate any data is if it can't find the default network. Try putting the correct network in the same directory.
