What is the difference between GCC 4.2 sse and the regular 4.2 sse?

Thanks

Hello Jim,

AsI had some bad experiences with the last releases and very fast bugfixes I will wait a while.

I am a bit sceptical about the huge diverity of special compiles for this or that.

Here is an example:

This is the special i5-i7 compile ON A AMD-PHENOM2:

While the intel compile is marginal faster on the AMD than the normal one the nodes per depth are not identical and the selective depth is different as well.

That are basicaly two different engines.

Hi Ingo,

could you please run

Code: Select all

./stockfish bench
from the command line and see what searched nodes you get? You should have 5416292.

Thanks

I tried both on my Phenom II X6

GCC i5-i7 SSE42

The output of the bench command looks identical in both cases as regards the pv

As the GCC is faster and runs on AMD and Intel. The non GCC compile is redundent.

I get different pv with both versions which means that one version is somehow "strange". Whichone is a different matter.

Did you try stockfish bench ? The PVs are identical for me. I'll try a GUI and see what happens

Since the 'bench' test reported same node counts I'd assume the 2 binaries are 100% equivalent. Neverthless becuase you reported differnt pv it is interesting to understand better. Could you please post what kind of test have you done?

1) From command line or from GUI ?
2) Number of threads set or let SF to choose automatically ?
3) What command did you give ? depth limited, time limited, infinite ?

Thanks

Hello Marco,

Where must type this command?
