Nice picture above, did you create it?

[BTO7]

Sure did ....when Houdini first came out. Its a combined photo shop job with special fonts i used and a blended pic of a couple different pictures blended into one. Tried to give the logo that magical look and of course your more then welcome to it.

Hey guys,i have also Houdini 1.03a as my number one!

Have you played with Large Pages On or Off ?

I have run my tests with Large Pages On ..now some people say that these LP hurts his performance?
Has somebody check this..for sure i will try running games without LP to see the difference!

Houdini sends some extra information about the usage of Large Pages to your chess GUI, you should be able to find it in the UCI log files.
When the Large_Pages option is enabled, and your Windows account has the privilege to "Lock pages in memory", Houdini will send one of the following two texts:
- info string XXXX MB Large Page Hash used
- info string XXXX MB Large Page unavailable (OS Error #), using standard pages

It's important to note that very often the Large Page allocation will fail when you're requesting a large block of memory. Windows memory gets fragmented quite rapidly and Windows will very often not be able to allocate a sufficiently large block of unfragmented memory.
When the Large page allocation fails, Houdini will fall back to using normal memory.

You can quickly test this outside your chess GUI. Simply double-click the Houdini exe and enter the following texts in the console:
- setoption name Large_Pages value true
- setoption name Hash value 512

I don't expect any situation in which enabling the "Large_Pages" option would generate a performance loss.
