I think it was an 8 processor system based on large cache Pentium III Xeons running at 900 MHz. Nothing like 2.4 GHz.
It costed an arm and a leg, but the Sheik could probably afford it.

I assume that all mamer commands remain the same, and that it is just a small modification to the Swiss format? Indeed, for the tourney type you can also choose 'm' for McMahon, next to 's' for Swiss and 'r' for round robin. I will discuss it with Liesebeth. First I have to find out what went wrong...

LeelaRB was playing on a low cost Ryzen 7 3700U laptop, using the DX12 version of v 0.26.0 running on the integrated Vega 10 graphics. It lost one game horribly, not sure why that was, but otherwise it seemed to play pretty well. Before the tournament Nightmare played some games against LeelaRB and...

After replacing mamer with the old one everything was stable again. Because we lost half an hour due to all the issues we decided to play nine rounds. In the end Belfish ended on top. Nightmare was very lucky this time and had a chance to win the tourney, unfortunately he (or it) dropped a half poin...

There is a very strange issue with the server at the moment. The only thing that has changed is mamer, In the mamer config header I increased the max. number of rounds from 10 to 12 and recompiled. We also run a test tourney with 20 players and that went fine. My guess is that the old mamer is compi...

The 4/1 is fisher clock: 4 minutes for the whole game and 1 second increment per move (this is per player). When we assume a game takes 60 moves, a game would take 10 minutes, the tourney with 11 rounds would take 110 minutes. In practice though the tourney will take about 2.5 hours.

Oh, I see. The version of mamer you are using doesn't implement McMahon. I never pushed that patch to my source-code repository. :oops: Anyway, I did that now. So it is available, if you want it. In fact I used the fork of Daniel Dugovic which is based on your repo of 4 years back. It has some thin...

It is usually more efficient to play the McMahon system rather than pure Swiss. Because with such a large strength range of the participants the first 2 or 3 rounds of pure Swiss are wasted on differentiating the field such that you get interesting pairings, rather than guaranteed 1-0 results. Yes,...

If you do IID / LMR / PVS re-searches, you would still have to redo the move generation, and it makes some sense to count that. For this reason I never do the re-searches, but instead let the node self-deepen or open the window. So that it can keep the move list and any sorting it has already done ...
