IvanHoeV55m. by K.L.O, 32 ,64 bit (aka 9.55a . 9.55b )

http://www.multiupload.com/1XJ85RLQY5


First impresions as we test is that this engine is UNBELIEVABLY SLOW as regards kNs per second ,,default on time buffer perhaps ?

second impression is ...its loseng to 97.b at moment

from another forum

Ivanhoe 9.55b x64 is only using 1 thread on my Core i7
(engine from http://chess.cygnitec.com/engine/ivanhoe/, compile x64 popcnt)

Tried to change the Threads parameter in the engine parameters but doing that I don't see any change. Is this a bug?



~~~~~~~

This could well explain the dismaly poor kN/s and performance , i try to get task manager up on our pc to check..


Task manager shows fluctuating cpu usage as low as 25% ( i am not knowledgable as to cpu / pc performance but there is very likely an issue with this compile

Please check on yours and post responces

Please recheck number of threads box in paramiters ,this compile does Not auto detect your cores as previose release does

Twice we have had to reset it but now we see significant improvement in kN/s speed ( now approxametly same as 9.57b ) and in performance as it is now beating its predecessor

when i try to install this engine in arena GUI (have not tried to some chessbase interface yet) i get this message

Fom the F*****T*** ...who made compile

IvanHoe999955m has been re-uploaded due to many broken parts in previous build -- the most being RobboTotalBase loading, but not working. I strongly recommend you re-download (using link posted by Eduard) as a few things were corrected. IvanHoe, with _proper_ time management configuration, is now stronger than Rybka 4 or they are on par.

Edit: Forgot to add only Capitalist users are affected.

B*** forgot manners as well ,hes more a capatalist than most , and an ignorant muppet

Whilst we wholeheartedly agree with "Doppelgangers" post we also see a great improvement in KLO's badly named 2nd compile of v55 , it still has issues re the reading of bases but when it does read them it is very strong, stronger than Ahmeds T55 on AMD chips anyway, here are some words from KLO


Important IvanHoe Settings

Postby kingliveson » Tue Jul 06, 2010 2:47 am
I like the following settings combined with RobboTripleBases:

Repeating Time Control

Code: Select all
TimeEasyFactor 14
TimeOrdinaryFactor 64
TimeAbsolutePercent 24
BufferTime 2000



Sudden Death Time Control

Code: Select all
TimeEasyFactor 13
TimeOrdinaryFactor 48
TimeAbsolutePercent 20
BufferTime 2000



Incrementing Time Control

Code: Select all
TimeEasyFactor 15
TimeOrdinaryFactor 60
TimeAbsolutePercent 20
BufferTime 2000



These time management settings are based not just on sample games posted, but also through analysis and observation. Chances are they are not optimal. Also, only tested blitz games with ponder off. Am most unsure about the repeating time control -- still working on it.

AllowInstantMoveFromHash should be off -- only good for hyper-bullet matches in my opinion. It is designed for ponder off games, but I think it has a negative effect.

Pawn Hash is another important setting; it should be 1/16th of total hash size. For example, if Hash size is set to 512 MB, Pawn Hash should be 32 MB. You can get away with 1/8th, but anything larger will have a negative effect.
