Anyone have any idea when SF9 will be released?
Parent - - By leavenfish (***) Date 2017-08-28 01:23
Sure...just as TCEC starts. :cool:
Parent - - By cghori (**) Date 2017-08-28 03:49
When does TCEC start?
Parent - By Venator (Silver) Date 2017-08-28 14:36
End of September / beginning of October.
Parent - By Ray (****) Date 2017-08-28 06:48
Or after it finishes ?

As always when the new version is >50 ELO compared to the previous version.
Current dev is 'only' +30 yet, so no release soon.
Parent - - By Geomusic (*****) Date 2017-08-31 15:28
50+ ELO seems like a stretch...do you think it will make it?
Parent - By Fulcrum2000 (****) Date 2017-08-31 18:21
Sure it will, just not sure if it will be at that point when TCEC ends.

At which time control, match conditions and hardware base as a standard? Is there a standard for measurement to determine when 50 Elo is achieved? I don't know of one.

OK, thanks

I just use the latest version anyhow -never really bother with running 8 as a standalone. Sometimes I run across issues with the most recent version posted but for the most part they seem to do the job.

Probably tomorrow, waiting on the final executables to be generated.

That are not the final executables, those will be released tomorrow via https://stockfishchess.org/

(the new exe's will be functionally identical, but faster)

Fundamentally it is Stockfish 9!  mstembera -stated clearly "Official release version of Stockfish 9 "

I would agree that he has perhaps jumped the gun!

I still see SF8 https://stockfishchess.org/
or is it just me? :)

Anyone know of a good, faster compile yet for SF9?
Parent - - By QueensideCastler (**) Date 2018-02-06 09:56 Upvotes 1
I recommend Cfish 9 by Ronald De Man.

Parent - By leavenfish (***) Date 2018-02-07 04:50
Why do you say that? Posts on Talkchess is indicating it is actually slower than SF9.
Parent - - By Peter Grayson (****) Date 2018-02-07 16:17
The Brainfish compile is the same code as SF9 with the benefit of LP hash. It only becomes Brainfish with the use of the Cerebellum book.

In single thread mode, it gives exactly the same output as SF9 but significantly quicker dependant upon you hardware and O/S set up.

Stockfish takes 20.9% more time to reach the same position than Brainfish.

Peter thanks - I completely forgot their might be a Brainfish compile!
Parent - By Dragon Mist (****) Date 2018-02-08 19:26
Large Pages will do that, yes. Folks should note that using LP will put that much more stress to their CPUs (the same as additional overclock) i.e. higher temps.
