[elcabesa]

with pleasure I'd like to announce the release of Vajolet2 2.4

this release consist mostly of debugging and refactoring, I hope it adds few ELO point to the previous release.

I'd like to thank:

• Dann Corbit, Jon Dart and Peter Osterlund for their help in find and solve multithread bottleneck.
  
  Jurgen Precour (LocutusOfPenguin) for the help with cmake and Raspberry build.
  
  Thomas Petzke, for his post on his "Standard Algebraic Notation Headache"
  
  Tcec boys for their beautyfull tournament, expecially Anton Mihailov .
  
  CCRL boys for their incessant work.

Thanks Marco. I hope you keep improving your engine.

[elcabesa]

I'll try, but it's more and more difficult to improve it

[LocutusOfPenguin]

Thanks Marco.
Just in time for my 0.9k release

[elcabesa]

Thanks Marco.
Just in time for my 0.9k release

is your program the core of the "DGT Pi - Chess Computer for DGT e-Boards"?

[LocutusOfPenguin]

And with this upcoming release yr engine is part of it ....But this version is not "sold" right now...im always ahead , ha - but its part of auto-update.

Thank you for the new version, Marco!

I've tested it in my 60+0.6 sec. rating list http://www.fastgm.de
At this time control Vajolet2 2.4 had 422 time losses, in total of 15250 games, Vajolet2 2.3 only 24 time losses.

GUI is LittleBlitzer 2.74, default settings, Ponder false, OwnBook false
Maybe you can take a look at it.

Best regards,
Andreas

this result is really strange for me since i usually lety Vajolet play tournamet games at 6''+0.05'' without any timeout.

are you using your pc for only the games, or you are doing sone other works while the tournament is running? can you give me some more informations or debugging logs?

[fastgm]

For this rating list I'm using a HP Z620 Workstation, Dual Intel Xeon E5-2670, 16 cores, 15 games are running at the same time, 1 core is free for Windows OS activities.
Of course, the workstation is not touched during all my tests. All other engines do not have a single time loss. That is the reason why I'm reporting this curious behavior.
Unfortunately, the LittleBlitzer GUI does not generate a log/debug file by default.
