Crafty 11.15
Robert Hyatt
If you downloaded the source or executables for 11.15 today, please
copy the source again. I should have realized there was a problem
when I found a 400mb log file this afternoon. Every now and then
Xboard gets into a real snit and produces a monster log when ICC
and Xboard lose a connection in some unclean way. This filled up a
disk partition and when I released the source, it was not a complete
version, but had a few old modules as well, which were incompatible
with each other.
Someone reported seeing some Mat00 scores (which makes no sense.)
I couldn't reproduce it, but found later that the source was not
correct. I'll get Jason to compile them again for those wanting
executables.

OK, but i missed the precompiled linux-executable.
And one more question: What is the reason for using the old a.out
format? The Pentium-optimized ELF Compiler is available. I use it
without problems.
After stripping the ELF-executable has 332084 Bytes. With the a3-test
it spites 61115 nps on a PPro200MHz (hash 24M, hashp 5M).
This only for information.
By the way: If i want to compile the source for LINUX in ELF-Format,
i have to replace the cc order in the Makefile to cc = gcc, because
i run a ELF system. This only as tip for the other guys.
Next weekend the first big test for 11.15 will run.
Will see, what Rebel-Decade and Ychess have to say to the new
version. :-)
And at last one word: I would like to scroll back the noiseoutput
in the ascii screen. In LINUX no problem, the bash has this as
feature. But in DOS i miss this.
And i love this program.
cheerio and thank you.
Peter

Using wcraftyt-11.15.exe will produce Mat00 scores.
So I assume wcraftyt-11.15.exe is not the real 11.15 version.
IMHO crafty-11.15 is the first crafty to solve

Hmmm... hope it still does after the recompile is done. :)
In any case, 11.15 executables are not there yet, just keep checking
the dates. The source is ok now and I'm running exactly that on ICC
with no further oddities so far...

This surprises me. What is the technical explanation for this? Does the
same thing happen with all programs? Could I speed up my own program by 10%
just by compiling it to a.out format?

I'd suspect so, but you should definitely try. Speculation has it that
perhaps the ELF format dedicates one register for something or other, which
is one of a very few registers in the X86... I have not tried to look at
the assembler output, but have run a bunch of tests... a.out is faster for
(to me) unknown reasons...
Steffen A. Jakob
From the ELF-HOWTO:
-------------------
It's not intrinsically smaller or faster
You may well end up with smaller binaries anyway, though, as
you can more easily create shared libraries of common code
between many programs. In general, if you use the same compiler
options and your binaries come out smaller than they did with
a.out, it's more likely to be fluke or a different compiler
version. As for `faster', I'd be surprised. Speed increases
could turn up if your binaries are smaller, due to less swapping
or larger functional areas fitting in cache.
Jason Deines
Also from the ELF-HOWTO, at the very start of the document:
(The advantages are first listed:)
It is much simpler to make shared libraries with ELF.
(snip)
It makes dynamic loading (ie programs which can load modules at
runtime) much simpler.
(snip)
(Then the speed issue is mentioned:)
Against this it must be weighed that ELF is possibly a bit slower. The figures
that get bandied around are between 1% and 5%, though all the actual tests
that have been conducted so far indicate that the difference is small enough
to get lost in the noise of other events happening at the same time. If you
have TeX or a Postscript viewer/printer, you can read speed.comp-1.0.tar.gz,
which is available from SunSite somewhere.
The slowdown comes from the fact that ELF library code must be position
independent (this is what the -fPIC above stands for) and so a register must
be devoted to holding offsets. That's one less for holding variables in, and
the 80x86 has a paucity of general-purpose registers anyway.
---------------
I'm not sure why the statements in the HOWTO contradict each other, but there
you have it. Real-world testing by me using crafty shows a 10 to 15%
performace hit for ELF using the default gcc (2.7.2.1). Others have mentioned
similar findings.

They don't. Normal code should be compiled identically whether the format is
a.out or ELF. Only during library is one extra register (ebx) unavailable.

I'll try this myself today, but is there a difference whether you link the
executable statically or dynamically?

I'm a bit confused about this Nolot position. It is not one of the

Stobor gets and keeps this after 4 seconds on a p5/100.
It's now crunching 16 ply with a score of +7.38...
Is this hard for other programs??

Sorry for interrupting, but could you tell me reliable where I can get
this Winboard or XBoard? I'd like to have a graphical interface, does this
present me a chess board or what is this good for?
The 2 or 3 european crafty-ftp-sites don't seem to offer xboard or
winboard, any source?

It should be available at any ftp site that keeps chess-specific codes, like
the various server interfaces and so forth.
log on to ICC, and "finger mann" to get a link to the current source code
for xboard/winboard...
John Stanback
I think this must be pretty easy. Zarkov takes about 7 seconds on a
p5/100...
