Is anyone else finding the archive not credible?
[d]3q1bk1/5p2/1p4p1/6Pp/2P1Q2P/p4P2/R5K1/8 w - - 1 46

This was Houdini vs LC0 eval from the archive
Houdini : +7.40 46 Kg3 Be7 47 Kf4
LC0: +1.19 46 Kg3

The game ended in draw with Houdini selecting 46 Re2 and a new eval of +2.05 Houdini/ +1.33LC0. I couldnt find any engine on desktop that even hinted there was a white advantage on move 46. And then when I entered 46 Kg3, they all went advantage to black. Not the only game where the archive was ?????

Would this position would be covered by the tablebase with white having 6 pieces and black having 8?

Would this position would be covered by the tablebase with white having 6 pieces and black having 8?

No. Current endgame tables are for no more than 7 pieces total, including both kings.

Oooh...thanks! Shows how much I know about that!

Here is a sample for the impacted engines, one for each.

Its clear that, on occasion, some threads will get blocked out by the scheduler. After doing some more reading, I have some good examples of this kind of behavior. It is common for engines to only report (printing) from the main thread. These outputs show, I believe, that some threads will get CPU time, and until the main thread is given a chance, the engine is partially stalled. The problem arises if once the main thread gets a chance to run, it immediately exits after depth 1, for fear of running out of time.

Below is taken from the logfile. Here we see the first depth taking an astounding 4672ms, and then suddenly the next 9 depths (and many more) are completed instantly.

An example for Texel, which is a bit different, and shows not the problem of getting the initial thread access, but of holding onto it. Here we see texel lose main thread access for about half a second, and once regained the depth outputs come flying out. PV output cut by me.

I have thousands of examples, for the original six, plus now for Texel.

One last example of any engine getting borked by thread time allocation. The following are outputs from games played by Fire.
You will see some empty lines in the output. These are when Fire's opponent reported a "bestmove" (Finished their move).
All of these examples are ponder hits. So Fire continues the active search.

This either proves that 1) Fire has issues when getting a ponderhit, or 2) When the new threads are spawned for the opponent to ponder with, Fire is crippled for a few moments.

In previous posts I cut some data out -- but here I'm keeping it verbatim, in case Norman would like to verify.

We'd certainly also not be happy if FIRE missed the cut because of the way it handles PONDERING

There are currently 4 engines within half a point, Shredder, Ethereal, Andscacs and Booot. Maybe they could change the rules and do a top 9 for Stage 2, instead of top 8

[elcabesa]

there is a link where all the game logs can be downloaded?

just a note, game logs are not complete engine output because to save space arena is logging "a lot" instead of "all" according Norman

I've requested the logs from Erik, who said he is looking into it. I suspect this will be the Arena logs, so not quite complete as you want.

If you are interested in taking a look at Vajolet output, I can say I've not seen anything out of the ordinary. Although I only have 4/5 games to go on.

It would be interesting to see what happen in vajolet games because the version playing cccc is a really a big thread spawner.
It create all the thread and join them for each iteration of iterative deepening

Something like:

Code: Select all

For ()
  Depth++ 
  Spawnthreads ( Alphabeta )
  Main alpha-beta
  Jointhreads ()

In the hypothesis that the system could stall when creating a lot of threads, I think you should see a lot of system problems when vajolet is playing.
Do you see any problems in opponent of Vajolet or vajolet itself?

I posted a dropbox link earlier in this thread, you can take a look for yourself.

The first 6 engines I posted about have glaring errors in the logs. The next 2 are more subtle.

If your guess is correct, maybe a higher sample size will show it. It seems to matter who is playing, both engines.
