Re: AMD Ryzen

Rumors indicate that also a 16-core Ryzen is in the works :) Bert Indeed! There are also rumors that AMD will add 4 way interleaved memory to Ryzen to make it competitive with Intel HEDP. However one of the lead developers of Ryzen says that there are no intentions to add 4 way memory, so I don't k...

Re: Search Algorithm

Bert, Right now both my machines (8 and 10 core) are busy producing a huge number of games of considerable depth, if you wish I can run your experiment at a larger depth when this job is finished. As an alternative I am willing to give you a remote login to my 8 core machine (which is on a separate ...

Re: AMD Ryzen

First Ryzen, now Napels. Who needs 32 cores :D ? Bert Not my cup of tea, for the things I'm typically doing a few fast cores are usually better than many slow cores. I hope that the renewed competition of AMD forces Intel to do something about these weird prices, a top of the line workstation would...

Re: English Checkers

You can't convert a program from 32 to 64 bit when you don't have the source code, converting a binary program is virtually impossible. Checkerboard needs the engine to be a DLL, this complicates things even more, the engine you are talking about has it's own GUI and it seems it also needs the engi...

Re: English Checkers

I have a request for people who know how to program. I have a certain engine checkers English 32 bit along with the base ends. I'd like to convert to 64-bit with the base ends, so to use engine under the program CheckerBoard. The person who will do it heartily thank you. The file with the base endi...

Re: ENGINE SPEED AND STRONG

To avoid any further dreadful conflicts I changed the pattern evaluation to use 6x4 patterns combined with 4x6 patterns, 5x5 patterns cannot overlap equally or I have to let them overlap for 4 fields which seems overkill and I don't like the fact that they not always contain the same number of bits...

Re: AMD Ryzen

Based upon the first benchmarks 8-core processors, for acceptable prices, and with an interesting performance, become realistic. And the call them AMD Ryzen.... Bert Indeed, they come very close to the 6850K and 6900K processors, still with a lower IPC, but AMD compensates for that with a higher cl...

Re: ENGINE SPEED AND STRONG

Haha, than I think we have a different opinion, without coding your data won't go anywhere, remove the search from your program and you will see how good it plays. Program = code + data. If the data isn't yours, how can the program be? I own both Scan's code and data, so I can call it "my program"....

Re: ENGINE SPEED AND STRONG

Really I don't know what you mean, every line of code is original and written by me. Code is slowly becoming obsolete. This is the ML era; data is everything. Replace my data with zeroes (AAAA with your encoding), and you can claim authorship. Not before. Haha, than I think we have a different opin...

Re: ENGINE SPEED AND STRONG

And draughts seems to be very insensitive to calculation depth (unfortunately), yesterday I ran a match between two versions of my program, one being on hardware 20 times faster as the other, the fast version won the match but not by a very great margin, not what you would normally expect with such...

Re: ENGINE SPEED AND STRONG

Krzysztof, within the context of the discussion, wise words are welcomed. Bert Too many attribute to the strength and power of the processor and it is not so. Let me give you an example. It is a tournament game Damage - Scan. Damage game on hardware: processor - PHI - 72 cores ram - 256 GB Scan gam...

Re: ENGINE SPEED AND STRONG

We can easily check that it's no secret. Let's ask Krzysztof, Catherine, and Sidiki (not to mention others) whether it was 100% clear that Argus was actually using Scan's evaluation function (and not just the idea of 4x4 patterns which would have been OK). I had assumed that Joost generated these v...

Re: ENGINE SPEED AND STRONG

The program temporarily uses your 4x4 evaluation data and not your evaluation function as a whole, it is my intention to have this data replaced pretty soon because I'm going to switch to larger patterns anyway. Maybe this was not clear to the average reader, well now it is. Now I have to rethink w...
