New Zappa Version Ready for Download

[Volker Pittlik]

Release Notes:

1. This version _might_ work on Athlon/P4 (certainly the Linux version
should). You people and your obselete computers . . .

2. SMP support is enabled,but I suggest windows users avoid it. For
some reason my machine practically freezes. I don't know whether this
is due to the spinlocks or some other issue, but who runs Windows on a
multiprocessor box anyway? On Linux, this version _should_ work with >2
CPUs, but it hasn't been extensively tested.

3. The eval has been considerably bugfixed since beta1. Whether this
makes the program stronger or not, I do not know.

4. UCI _should_ work. I was able to run several games in both Arena and
the Fritz7 GUI, so give it a shot and see if it works for you.

5. Book editor is released (and a small default book based on
gm2600.pgn).

Thank you Anthony.

BTW: It does not run on my AMD XP .

[José Carlos]

Doesn't work on my Athlon

[Anthony Cozzie]

Honestly, this is annoying me quite a bit. I specifically told MSVC++ to optimize for P3. Well, I have one more trick to try, if that doesn't work I'll just give up.

[José Carlos]

If you want, I can try to build it for you here. I have an Athlon 1.33 (win2k) and an Athlon MP 2400 (two processors) (winXP), and MSVStudio.net

Hello Volker,

I notice that Zappa has 512 mb set in its hash tables in the ini file. That setting will knock out most machines.

Try reducing it to say 64 mb and see if that helps. It seems to be running here.

I set it to 64Mb before trying to run it.
Is there any other parameter you changed?

[Anthony Cozzie]

Roger: Ooops, sorry about the hash thing.

Jose: I like you, but I don't like you enough to send you my source

Hello Jose Carlos,

Nope. Sorry about that.

Hello:
It does not run in my PC with P3 neither in other with P4
Pablo

[Olivier Deville]

Here Zappa works on my PIV and should work on my Athlon64 too - not tested yet.

But if tbs are enabled, it will crash in the endgame. This was already noticed in the former beta version. With tbs off, it works fine.

I tried every possible setting between 2 an 256. Without luck unfortunately.

Oliver: does it actually crash, or does it do some sort of stack dump? (check the log file).

Roger: I guess you have an athlon 64

Also: Is this version working in UCI interfaces for people? I heard a lot of problems with the last beta.

I want to try to iron some of these things out.

anthony

[Guenther Simon]

Would be nice if you would read my bug reports in RWBC for
test tourneys sometimes
The previous beta performs illegal moves in tablebase positions
sometimes and then it crashes.
(I have 2 debus with that behaviour saved if you want to check them)

Cheers,
Guenther

P.S had no time yet to test the beta2

[José Carlos]

Jose: I like you, but I don't like you enough to send you my source

Of course, I just wanted to help.
If you want it anytime, just email me. You have my word I'll destroy the source after compiling.

On my P3, WinME, running this new Zappa in console mode, the console window closes after about 5 seconds, with this output in zappa_log ...

zappa_setup(): initializing move generation tables: 8ms
zappa_setup(): initializing evaluation tables: 0ms

set_option(): threads = 1
set_option(): scorepov = 1
set_option(): kibitz = 3
set_option(): book = zappa.zbook

So if it won't run in console mode, it won't run in any interface.

Hello all,

This is an update. On my lowly Pentium III at home it crashes after about ten seconds.
