I am missing the operating system you are running on. I could note make it run (for the IPON) in XP64 (AMD PH2 + i7) while starting it in W7x64 (i5) was no problem. I assume it is optimized for W7 which is no difference to the xp64 compile (tested with JA for the latest stockfish).

I send an email to the author and hope for a new compile which is running on XP64 AND W7.

I'm using Linux. More precisely

Code: Select all

lucas@lucas-desktop:~/Chess$ uname -a
Linux lucas-desktop 3.2.0-18-generic #29-Ubuntu SMP Fri Mar 9 21:36:08 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

I'm running the 64 bit Linux compile from the author. The author provides Windows and Linux compiles for both 32 and 64 bit. I don't have Windows, so I haven't tested the Windows compiles.
So the win 64 compile from Borko doesn't work for you ?

[IWB]

Hi.

...So the win 64 compile from Borko doesn't work for you ?

I am pretty sure not just for me - as long as it is W-XP64 as well. It is just a compiler option which has to set back and it will run exactly as fast as an now.

Hi,

Maybe someone (Jim?) can make a new windows compile ...?

If so, thanks in advance!

Hi Ingo,

If you compile on Win7 with Mingw then engine will have Win7 api dependency >

I have compiled Minko on Win XP x64 system (did a re-install on a spare partition just for you)

Hi Jim,

First: Thanks a lot, Thanks a lot, Thanks a lot!

This x64 is running on XP64. Actually I doubt that it is just for "me". I know quite a few who still run XP64 on modern hardware. I would think that you should put a MinkoChess Version running everywhere on your web site!

Now the downside:

1. Is it really nessesary to have a dll file? I hate that. It would be much nicer to have just ONE exe running ...
2. The POPCNT version is only running on my XP64 with the i7, not with the Phenom 2's. (normal x64 runs everywhere!) I have no idea why and you do not have to bother with technical details for me but if this could be fixed as well I would be very thankfull. (The old UMKO was running with x64 and SSE42 on all platforms)

Nonetheless, thanks again!

Bye
Ingo

Ok, download again, same link.
Only one executable this time, no external dlls. Should use popcount if cpu supports it.

Thx Jim, that runs everywhere.

Just one question, I checked on an old Q6600 which doesnt support POPCNT/SSE4 and it runs there as well. Does it have some kind of autodetect for that feature or is it possible ybroken and not using POPCNT/SSE at all?

Besides that it works fine and again I propose to put it on your web page!

Thanks

You right. It's not using popcount.
Minko needs SSE4 defined for popcount support. There is no auto-detect.

Relevant code in Minko is this >

Code: Select all

#if defined(SSE4)
inline int __attribute__((always_inline)) bit_count(const Bitboard b) {
    int ret;
    __asm__("popcnt %1, %%rcx" : "=c" (ret) : "r" (b));
    return ret;
}

Download again, same link for popcount-enabled build.

Jim.
