Houdini 6 has been released

oops, SF still leading by 400.5/800, a full clearly distinguished half a point, so my first thoughts SF will still outperform H might be true, though all this might be very well just statistical noise.

www.inwoba.de is updated now!

time for a scientific second run now, including Houdini contempt 0 and latest SF dev.

Yeah, I d like to see that too

Anyway dear Lyudmil, we gonna have to wait for fast.gm to relase their result. I predict Stockfish dev being better than houdini at bullet, after that, I don't know what will be the result at 10 min or 60 min.

Ah ! And I forgot Stockfish dev was not tested at 10 min and 60 min !

I maybe didn't express myself properly. I try to see the scaling with time control, although the number of games will be insufficient for higher time controls. The first test was at 15''+ 0.15'', and Houdini lost, although by not that significant margin. The second test was at 60''+ 0.6'', and Houdini won, also with not that significant margin. The combined result is that on this time control span, the scaling is better for Houdini fairly significantly. 240''+ 2.4'' is probably the maximum I can get as time control with my CPU resources and time. We have to wait for FGRL results of Andreas.

Any plans on releasing Houdini 6 for ios? We desperately need a top engine for analysis for such power Apple has on its devices.
Hopefully it will be part of an app that supports multiple arrow analysis and drag and drop moving.

hi there

thanks very much for this release.

I have a ryzen 1800 cpu and "x64-popc" is apparently the version of H6 that is installed.

however, at an early stage, H6 isn't doing so well against Stockfish 8 at 15 minute games. (H6 8 vs. S8 9); which is surprising.

There was an earlier thread which suggested that you had to choose the right executable for ryzen for stockfish (http://www.talkchess.com/forum/viewtopi ... n+popcount). Is there some way of checking which is the right H6 version for Ryzen ?

cheers

Correct.
AMD Ryzen officially supports BMI2 instructions, but their implementation is very slow (the instructions are emulated, if I understand correctly). On Ryzen the BMI2 or "pext" compiles are about 20% slower than the POPCOUNT or "popc" compiles. The Houdini Setup is aware of this and will install the "popc" compile on AMD Ryzen.

however, at an early stage, H6 isn't doing so well against Stockfish 8 at 15 minute games. (H6 8 vs. S8 9); which is surprising.

The variability of engine matches is huge, that's why rating lists are comprised of thousands of games. Even after 100 games the error margins are close to ±40 Elo.

Will there be minor patches leading up to TCEC Robert ? You surely haven`t shown all you cards yet, have you ?

There are minor patches between TCEC rounds, not leading up to it. And why would he tell you if he had shown all his cards?

First of all I didnt expect Houdart to tell me or anyone else I just hoped that he would
Secondly, where did Robert confirm that he will update Houdini between TCEC rounds ? Robert can surely patch H6 before TCEC starts or in between rounds if he wants to....
