Crafty-22.9 is available

[zullil]

The new crafty seems to be somewhat faster than older versions in terms of NPS.

Only by about 1%, at least based on the following (admittedly scant) data:

Code: Select all

Crafty v22.8 (1 cpus)

White(1): bench
Running benchmark. . .
......
Total nodes: 111671982
Raw nodes per second: 2147538
Total elapsed time: 52.21

Crafty v22.9 (1 cpus)

White(1): bench
Running benchmark. . .
......
Total nodes: 114972412
Raw nodes per second: 2169290
Total elapsed time: 53.16

Perhaps Bob Hyatt can quantify the improvement more accurately.

Until Jim comes along and makes a faster one, here is a build with a 64 bit binary in it:

Hi,
is there any other link for download the .exe?
I get 100byte per second - and then download stopps.

On my machine it is 3% faster for bench, and I am comparing it to an Intel build which usually clobbers my build (by anywhere from 10-30%).

Hi Werner,

Here's a mirror link to Dann's x64 compile (mine will be along later) >

Jim.

Will you be compile one for winboard to be used in
Arena on Vista OS.

Thanks,

Gerold.

The new crafty seems to be somewhat faster than older versions in terms of NPS.

I saw up to 15M NPS in opening positions.
That's 7.5% of Deep Blue.

run it on a dual-chip I7.

So .. what's the speed on such a box ??

Interesting. I used the same compiler version and the same compiler options for both 22.8 and 22.9:

Code: Select all

darwin:
	$(MAKE) target=FreeBSD \
		CC=icc CXX=icpc \
		CFLAGS='$(CFLAGS) -ipo -mdynamic-no-pic -O2 -no-prec-div -static -m64' \
		CXFLAGS=$(CFLAGS) \
		LDFLAGS=$(LDFLAGS) \
		LIBS='-lpthread -lstdc++' \
		opt='$(opt) -DCPUS=2 -DINLINE64 \
                   -DBOOKDIR="/Users/Louis/Documents/Chess/Crafty/Books" \
                   -DLOGDIR="./Logs" \
                   -DTBDIR="/Users/Louis/Documents/Chess/Crafty/TB" ' \
		crafty-make

Hi Gerold,

I'm just re-compiling to incorporate draw offer bugfix. New compiles along
shortly.

Jim.

crafty has started to use c++ features in variable declarations?

iterate.c

if (iteration_depth > 3) {
time_used = ReadClock() - start_time;
int time_left = time_limit - time_used;
int prev_ply = ReadClock() - prev_time;
