64bit compile

[elcabesa]

hi, I'd like to test my engine in 64bit mode, can anyone make for me a 64 bit windows build with gcc and do some test of the engine?

I still havent' a 64 bit operating system

GCC is not my strength (none, go),
at the version 2.3 I compile with Intel, but had breaks in the game.

I looked at your code again and there is intrinsic to 64 bits, may not go far ahead.

Yet I have always noticed very little departure from NPS in Vajolet, guess which product is measured (nodes).

Good luck.

Hi,
I just tried, tell me where I start. Thanks

Code: Select all

gcc vajolet.cpp -o vajolet.exe
In file included from movegen.h:23:0,
                 from vajolet.cpp:34:
search.h: In constructor 'Search::Search()':
search.h:84:37: error: 'log' was not declared in this scope
search.h:86:69: error: 'floor' was not declared in this scope

I didn't understood your message.
Vajolet 2.03 didn't compile in gcc. I need to compile a new development version to 64bit and test it against the 32 bit version.

Yet I have always noticed very little departure from NPS in Vajolet, guess which product is measured (nodes).

what do you mean?

[velmarin]

I understand, poorly translated.
I just wanted to help.

Intrinsic in Bitops.cpp are in 32-bit format, there will be no profit.

Code: Select all

return __builtin_popcountl((unsigned int)bitmap)+__builtin_popcountl(bitmap>>32);

if(_BitScanReverse(&res,bitmap>>32)!=0){

On my computer, your executable Vajolet produces very few nodes, 500 in the picture.
Winglet you see, 2000.
I guess "how to measure the nodes is just different."
I hope help you.

More clever search => more work per node => less nps. More eval terms => less nps. So if engine A searches 4x faster than engine B in terms of nps, it may still be much weaker than B. Of course if B searches 4x faster than itself, the elo gain will be huge.

It is only an indication, Martin.
Thank you for your explanation.

Basically Vajolet is based in Winglet.
I worked hard in Winglet, this is a learning project, I ported it to 64 bits easily, and without loss of speed.

My thought is that perhaps the many changes of Marco, something is not right.
just a feeling.

thank you, vajolet 2.03 didn't compile with gcc but my dev version will!! I'll send you a PM

[elcabesa]

the first one problem is related to use -std=c++11 , try it.

the second problem seem to me you have compiled vajolet.cpp to vajolet .exe. but you need to ompile all the cpp file and then link them toghether, am i wrong??
