New CFish Windows binary (from today's code)

[Dann Corbit]

The "Cfish-vanilla.exe" binary is fastest for me.

Thanks, Dann. Do you have any speed comparison data with the original program?

It is hard to make a clear standardized comparison because the bench changed and Cfish does not have the new positions.

It is a lot faster for me, depending on the position, up to twice as fast.

For me, the "vanilla" version is fastest.

The vanilla or modern binary is not working on my popcount system

Hi Paul,

Have you tried to compile it?

I just go to the folder where the source is, open a windows console, type "make clean" and then type "make cfish" (without quotes)

It worked for me.

Carlos

Modern version is really fast and good on my System.
How can I get a BMI version ?

"twice as fast"? According to "bench" CFish is 12,5% faster than abrok compile. But for some reason Cfish loses almost 10% of games in LittleBlitzer, when time control is 10s + 0,1s! SF and asmFish only may be once in 500 games normally. Why?

Do you mean it loses on time? It should not behave differently in this respect from Stockfish, but this is not something that I have tested very well.

If the losses are not time losses but crashes, then I might be about to fix it (yesterday I noticed a problem which I will look into as soon as I have time).

Yes I mean time losses as seen in this log:

If I raise inc to 200ms no help!

[Jouni]

Average time per move (tpm) is for Cfish clearly bigger than Komodo's. Normal SF (abrok) uses less time always.
