Re: How to set the clock

Well, there is nothing wrong with that if you use an increment of 3 seconds and the game lasted 80 moves (5 minutes + 80 moves x 3 seconds = 9 minutes). The question is whether a program actually goes below 0:00. If you want the external clock to be leading and have the possibility that a program lo...

Re: Internet engine matches

But switching off pondering, and hence the search threads, alone does not solve it. There can also be memory conflicts because of the memory used by the two programs for the transposition table and endgame database; Windows will then start swapping memory blocks from RAM to- and from the disk. Are ...

Re: How to set the clock

Do you ask because, in the next tournament, you want to display times for the audience that are better approximations of the internal clocks of both programs? My estimate is that on average it takes about 3 seconds for an operator to play a move on the board and to press the clock. Just so I underst...

Re: LAN without internet

Which other features and why? What else could be needed besides implementation of DXP follower? (and optionally DXP initiator)

Ed quite different can be done. You don't have to port forwarding.
Krzysztof, does this mean you have it working now?

Re: LAN without internet

I don't understand, why play DXP matches on two separate 4-core/8-thread computers when a single 16-core/32-thread computer is available? The best you can achieve on the two computers is two programs using 8 search threads and pondering. You can achieve the same on the single 16-core computer. By th...

Re: Internet engine matches

Okay, so it is probably not necessary to switch off hyper-threading. In engine matches either switch off pondering or use the rule of thumb that the total number of simultaneous threads never exceeds the number of cores.

Re: Internet engine matches

Krzysztof's machine has 16 cores/32 threads, IIRC. So theoretically 16 + 8 = 24 threads is possible. However, a hyper-thread is not the same as a real thread (core), so when pondering is used there can still be interference. I agree with Ed that switching off pondering when using two programs on one...

Re: Kingsrow - question

Krzysztof, is this what you want? Create a file test.pdn with content: 1. 34-30 In Kingsrow, after making a connection, choose Start match... , then select Start positions: read from PDN file , and select (by Browse...) test.pdn . Then Kingsrow will play 2 games, 1 with white and 1 with black, both ...

Krzysztof, can you play a match Sjende Blyn vs Scan 3.1?

Jan-Jaap
I am sorry to write so, but you have to ask the developer of the program Sjende Blyn.

Krzysztof.
Why didn't you ask him? You asked me.

But all right: Jelle, can Krzysztof play a match Sjende Blyn vs Scan 3.1?

Re: Unofficial World Championships Of Computer Programs Rapid 2019

Sjende Blyn is the only program in the top 5 of this tournament that does not use machine learning. In my opinion Sjende Blyn is a "tournament player", not a "match player": Originally I designed the program to play against humans, later on the focus shifted to play against programs (more tournamen...
