I running a blitz match right now (5' + 1") of Rybka 2.3.2a MP 64 bit 2cpu vs LoopMP 12.32MP 32bit 2cpu.  I know it's not a fair fight but I don't have any new programs to play vs Rybka.  Anyway the score is now 16-0 for Rybka.  That's the longest winning streak I have ever seen in my 44,000 + blitz database.  By the way Loop is hitting over 1M nps in the middle game so I don't think any thing is wrong with my setup.

Guess I spoke too soon.  Loop just got a draw!  So now +16 -0 =1.  :)

Loop's nps seems too slow. According CSS, Loop 10.32 (single, obviously) does 1342 knps in the middlegame on Athlon 64 X2 4200+. What's your hardware?

Loop does not auto detect threads - if you want it to use 2 you have to set the parameter to 2.

Hello Harvey,
I'm using a 64x2/3800  (not that fast).  But a check with the task manager shows Loop is indeed using 2 threads.  The nps varies quite a bit in the late middle game it's hitting 1.5M.  Rybka is hitting about 200K at the same position.  Right now the score is +32 -0 =7.  I will stop the carnage at 40 games.  Rybka is winning the last game also.  So final is +33 -0 =7.  Loop never won a game.  Rybka is using RybkaII.ctg and Loop it's own book.   Loop had a run of 7 draws in 14 games and that was the best it could do.
I need to get a stronger program for Rybka to play with.

You will find that Hiarcs 11.1 UCI, using its own book, is very strong against Rybka.

Strange. 16-0 score is not very normal against a Top engine like Loop.

Are you sure that Loop is running enough well in your machine? What book are you using? Could you please post here some games or the entire PGN of the match?

Then again, in 44000+(!) games, just about any statistical anomaly can happen over a short period.

A little more info for non-believers.  I have played 121 games so far with Rybka 2.3.2a (single 32 bit XP3100) vs LoopMP12.32 (2cpu 64x2/3800) auto232 match.  Score is 95-26 for Rybka +225 Elo.  If anybody believes LoopMP 12.32 is a very good program then what does that make Rybka (bugs and all)?

Where did you go to get Loop?

I have not seen anywhere online you can get this program.
