working source for stockfish 1.6.2

[BBauer]

I posted the complete output.
As the compiler produced an executable it also must have done the linking phase. It is reasonable to suppose that your suggestion will not work.
Anyway I will give it a try - at Monday.
You know that there was an issue with stockfish 1.6.2 an the g++ compiler.
Now there is an issue with stockfish 1.6.2 and the intel compiler.
I wouldn't think that stockfish is right and both compilers are wrong.
kind regards

Now there is an issue with stockfish 1.6.2 and the intel compiler.

I built a working binary using Jim Ablett's source and the Mac version of icc.
I used optimization and even pgo.

I have since upgraded my OS and no longer have icc, so I cannot redo it on this computer.

I'll try a clean build later at home, using icc on my MacBook.

Please go in the directory with SF sources open a terminal and give the following commands:

Code: Select all

make clean
make icc > tmp.txt

then post the content of file tmp.txt, in my PC I have

I am using Intel compiler 11.0 under Mandriva Linux.

Please, do _EXACTLY_ what I suggested to you, no more no less, it is very important you follow the steps carefully, otherwise we could miss something.

Thanks in advance for your patience.

It works fine here too.

Host: i7 920 with Fedora 12 x86_64
Compiler: icc (ICC) 11.1 20091130

Code: Select all

$ make icc
$ ./stockfish
Stockfish 1.6.2 64bit. By Tord Romstad, Marco Costalba, Joona Kiiski.
Good! CPU has hardware POPCNT. We will use it.

You have a nice system, I suggest to recompile:

Code: Select all

make clean
make icc-profile-popcnt

It will be sensibly faster.

You have a nice system,

Thanks. It was on this system that I first tried popcnt with Glaurung, but that was at a time when Tord wasn't working on it a lot. Glad to see he changed his mind

I suggest to recompile:

Code: Select all

make clean
make icc-profile-popcnt

It will be sensibly faster.

Is there a "standard" way of testing speed-ups?

[ldesnogu]

Either the internal benchmark is misleading or gcc beats icc:

Code: Select all

$ ./stockfish-gcc bench 32 1 10 default depth >/dev/null
Total time (ms) : 3272
Nodes searched  : 4569519
Nodes/second    : 1396552
$ ./stockfish-icc bench 32 1 10 default depth >/dev/null
Total time (ms) : 3692
Nodes searched  : 4569519
Nodes/second    : 1237681
$ ./stockfish-icc-profile-popcnt bench 32 1 10 default depth >/dev/null
Total time (ms) : 3489
Nodes searched  : 4569519
Nodes/second    : 1309693

gcc is 4.4.2.

[mcostalba]

This is interesting, on my PC icc is faster, please try with a bit longer test like:

Code: Select all

$ ./stockfish bench 256 1 13 default depth >/dev/null

[ldesnogu]

Same:

Code: Select all

$ for i in stockfish-*; do echo "**** $i"; ./$i bench 256 1 13 default depth 2>&1 | tail -4; done
**** stockfish-gcc
Total time (ms) : 29638
Nodes searched  : 42390880
Nodes/second    : 1430288

**** stockfish-icc
Total time (ms) : 33152
Nodes searched  : 42390880
Nodes/second    : 1278682

**** stockfish-icc-profile-popcnt
Total time (ms) : 31206
Nodes searched  : 42390880
Nodes/second    : 1358420

What versions of icc and gcc did you compare?

I've had mixed results with icc in the past, and most were in favour of gcc. The only recent exception is Richard Delorme EDAX that gains about 5% with icc.

Did you compile gcc with -DUSE_POPCNT ?

For instance please try to apply this to Makefile:
