Zangdar version 6.1
This is a correction , and "should" gain a little against version 6.

Zangdar 6.1 uses always over 1GB even when I set hash to 32MB

Hi,

Indeed. Its a problem, and Zangdar should not use this amount.
I will look at this, and will make a correction soon
Thanks for your help in testing.

Zangdar dev version down to 171 Mo during a bench (with 128 Mo Hash).
That why we need testers , thanks to them ))

Hi Philippe,

the question is ...
Have that any effects on playing strength?

I saw that too during my test-run but I gave it not a high priority. System have 64Gb Ram and no problems during 16 matches, runs to the same time without ponder, 5-pieces and 256Mb for Hash.

More a cosmetic flaw?

Hi Frank

Its not a cosmetic flaw, but a real problem. I didn't encountered it until I made a test with 32 threads. Then I got a stack overflow. So people with less memory will crash. I had to change the way I allocate memory in the code.
By the way I did a quick sprt test against the 6.1 version, and won some little elo ).
By default Zangdar takes now 170 Mo for 1 thread.
I hope its ok now.

Friendly
Philippe
