I was perusing the Rosetta web site yesterday and was looking at the computers that some of the top performers were using to crunch. Similar hardware to mine, but they are getting WAY more points per day average than I am on similar hardware, three times as much in some instances. I saw one box this guy had, an Athlon 64 3000, that was getting over 600 points per day!
HOW ARE THEY DOING THAT? 
Something smells fishy! 
Are there any tuning tips availabe that anyone has seen for tuning the client? I would love to triple my production without tripling my electricity bill!!!
I decided to add a link to show what I was talking about :
http://boinc.bakerlab.org/rosetta/ho...p?userid=43013
Look at computer ID 169797 or 169025.
This dude has a Sempron 2800 running Windows XP averaging 644 ppd and an Athlon 64 3000 averaging over 700 ppd!!!! That just is not possible.

Probably an optimized client.
What machine are you running? Memory? Disk space? Speed?
Is it running anything else or just that? Does it run 24/7?
Are you talking about RAC (recent average credit?)
Or are you talking about the amount of credit that shows up
given a block of work?
I'll use an example:
http://setiathome.berkeley.edu/resul...ltid=254706591
According to:
http://setiathome.berkeley.edu/resul...6496&offset=20
That block claimed 39.13 credit but received 29.46. After a while, that lost
credit could make one weep.
I'm basically doing Seti only for the moment but part of it is, I did not think
there was an optimized client for Mac protein folding - just Seti.
Alexkan could clarify this.

My computers are varied and many, but the one with the worst comparison ratio is my Athlon 64 3000. It is a custom built gaming machine with 2 GB of ram and 2 300 GB raided drives for 600 GB disk space. It has a high end ATI 256 MB Video Card. It does nothing but Rosetta for prob 22 hours a day and I use it for a couple of hours most evenings.
I was looking at Recent Average Credit, he had s similar computer (not as much stuff in it) that was getting over 700 points a day! I am getting between 200 and 250 a day on mine. We are both running Windows XP SP2.

I don't get it, you are asking PC questions in a Mac forum?
PC crunchers I know use Crunch3rs Optimized Clients + Tux Benchmark Optimization.
EDIT: uhm OK forget it, you are talking about Rosetta

No problem, it still amazes me that I have so many pc's around here. Thanks a lot for the link to the optimized clients, I am trying one now and will see if it triples my production!

I literally halved the amount of seconds it took for my Linux box to crunch a
seti block (from 14,000 seconds to just under 6000) by going to Crunch3r's
optimized client and switching from PC133 ram to DDR on that particular
box.
What is the Tux Benchmark optimization and how do I get it?

Oh, read also the last messages in the Altivec Optimized client thread:
talking about how to get more credit for a work unit depending on how
it is sent.

I have done quite a bit of reading on this now and I find that I believe that there is some cheating going on. I am getting around 40-60 points per work unit, but JeffreyLoaf is getting as much as 500 points for some of his and routinely get around 120 points for almost every one!

How on earth can you game a system like that? I don't understand how
you could cheat. I'd heard about cheats on Seti classic but I didn't get
how they were doing that either. And to what purpose? Just to be
higher up on a list than some other anonymous person? Ridiculous.

What do you mean, "How on earth can you game a system like that?"? Is that supposed to be a rhetorical question or are you showing your ignorance?

Call me ignorant then.
Okay, I can see WHY people would cheat but I'm not talking about that.
Unless you are specifically finding a way to EDIT the work unit while it is being
processed so it gains more "value" (which is artificial in the first place) which
then renders it valueless for science purposes.
Are you proposing that optimized clients are "cheating"?
I disagree.
Or is overclocking "cheating" too?
I disagree there too.
Or are you discussing the people who've found way to auto-install
the client on thousands of computers that aren't really theirs?
THAT is cheating in my mind.
Unless the work unit is being altered somehow to increase the rac value
I don't see how the system can be "gamed". But I've not been a "black hat"
in this so there you go.
I wasn't privy to "cheating" methods with the old clients, all I did is run
everything stock on a variety of computers and the like.
I can see the MOTIVATION to cheat, but don't see how it was possible unless
people were literally editing the code in the clients to modify the work unit in
some way to increase its "perceived value."
