Hey guys,
I remember reading somewhere that the original credit value for a days crunching was 100 cobblestones. Not sure if this number is correct but it will do for now.

Regardless of the speed of your machine and thus the number of workunits you crunch in a day, you were to get 100 cobblestones in credit.

Now if you only crunch 4 WU's a day you would get 25 credit each. 10 WU's would get 10 credit each. Thus the 100 credit per day.


This applies to a reference computer. The benchmarks compare your local computer to this reference computer, and adjust your claims proportionately. So if your computer is twice as fast as the reference computer it should earn 200 cobblestones per day. Also any computers that process the same task should claim approximately the same credit (optimized apps excluded), a pentium 100 running *nix should claim the same credit as a 3ghz P4 running windows XP.

Due to differences in OSs and hardware this does not work very well. The benchmarks also do not take into account memory bandwith or cache size which can effect the difficulty of the task. Having the application count operations should generate a more accurate claim. The SETI enhanced application uses this system and the claims are very accurate, 329.7, 329.6, and 328.9 for example. I have also seen workunits where all 3 returns claimed the same amount to one decimal place.

It is certainly true that the

It is certainly true that the app counts the FLOPs but it is the client that reports them and therein lies the possibility of a credit exploit.

Basically something is wrong here - science wants me to do more WUs, but gives me less credit for doing this. I am happy to donate the price of electricity for the crunching etc, but would like to have the credits reflect this.

Absolutly NOTHING is wrong with those claims.

Running the standard client compared to the optimized, will give you that exact difference.

The name of the game is OPTMIZATION.

I'm running opt on all 4 pc's right now, and MY claim is much lower than yours,

CAUSE I do a wu in less time than you, you on the other hand does in full time.

I claime perhaps 12 for a wu, cause I make it faster, you claime 40 cause you make it slower.

So where is the beef m8

Why more important claimed credit than granted credit for you?

edit: I don't say that claimed credit is unimportant!

Gotta to reply to meself, cause one of your pc's ARE running optimized, hence the difference.

Plz m8, bark on another tree

BTW m8 Plz look at this

BTW m8

Plz look at this wu

http://einsteinathome.org/workunit/6295743

I claimed 13.29 on an optimized cruncher. Guess what I got 13.29.

yeah life really sucks dont it m8 ??
