Gull 1.2 is out: https://sourceforge.net/projects/gullch ... p/download

Very nice, thank you.

Expect Gull 1.2 to play in TCEC C which starts in ~12 days.

edit: It says that it supports hash up to 2048 MB but when this is selected, the engine crashes (64-bit version).

Best,
Martin

Thanks. I'll load a fixed version to sourceforge soon. Thought malloc's gonna work with 2Gbs .
Edit: uploaded.

This compile works only under Windows Vista/7. I'll upload a fixed version soon.

Ah okay, so you removed the 2 GB option. Was a bit confused.

Thanks.

ThinkingALot,

it is a bad idea to automatically load LargePages on the computers of people who do not want them.

Matthias.

Why would one want Gull not to load large pages? This feature just provides tiny performance boost, nothing more. The same thing with automatic detection of hardware popcnt.

[ThinkingALot]

Of course if you'd like to have a non large page version for testing, just contact me via e-mail. Or you can just compile it yourself.
But from the user's point of view it's much better to have every useful feature turned on by default.

I can't see too why it should be a probleme to automatically load LargePages.

When I want those, I start my GUI with admin rights, and when I don't want those, I start my GUI without admin rights... (I have UAC on).

Gull 1.2 appears to be much weaker than I expected:(. Stronger than 1.1 but only by a small margin.
That's quite surprising since I carried out some tests on ultra short "time controls" (with fixed number of nodes per move) and obtained a substantial gain:

So there's probably a bug hidden somewhere.

But even your Elos are going down with more Nodes ...

I am still not sure if this ultra short testing is working. You/Gull 1.2 seems to be an example for overestimating the outcome and I remember the Stockfish team once to expect nearly nothing and it was a big jump in reality (1.6 to 1.7). Somehow the results seem not to be reliable with this Nodes/move method.
