I think sometimes I see things too black and white.
To me it seems a simple thing:
WU A has 600 "points" that need to be measured for lack of a better word. It gets 60 points..
WU B has 500 points that need to be measured.
It gets 50 points.
You get the idea.
I imagine it is a bit more complicated than that but I am sure the Baker people could assign a value to each WU with out too much difficulty.
If I'm wrong on that please advise me.
That takes care of the different amounts of work that different WU require and the machines speed(time) in doing them sorts out the rest
Simple? Am I missing something? Kills the cheating?
I might sound like a broken record but I fail to see why people want to make something that is simple so complicated.
you have a fast machine, it does more work units in a day than a slower machine it gets more points. No Benchmarks, no need for charts for different cpu's, no need for anything. The complexity of the work unit and the speed of the machine decide all the issues..

I agree. However, rather than spending their own money designing and implementing software specifically for the needs of Rosetta. They chose Boinc. There are a couple good reasons for this. One It's completely free, and two, you immediately get access to a huge possible database of volunteers just itching to give away their cpu cycles to a worthy cause, and three, existing boinc users, FAH users, and other DC project users aren't as likely to add a whole seperate program to their machines that makes them balance "priority" settings and such on a constant basis, not to mention cutting production rates by trying to run two memory eating apps at the same time.

So, Since they chose Boinc, they're stuck with what boinc offers (which is constantly changing to meet the needs of all projects/user). LHC has varied wus, some run a "predictable" amount of time, some smash into the wall and finish early. LHC couldn't possibly fairly assess the value of a given result before it actually crunched it. Seti also has short/long wu, WU of varied angle ranges, and just plain noisey (emi contaiminated) wus that finish in seconds. Other projects have their own unique concerns. So, Boinc settles for what "will work" for all projects, even though it's not the best for any particular project.

do you see my point?

The basic flaw in that design is that it assumes each 'point' is of a fixed time length. That is not always the case.

Now with Seti-beta they have found out that fpops works in general, but at each angle extreme it breaks down (this is where fpops doesn't work). i.e. it takes longer to, or it is very quick to, do a calculation before it can get back to saying 'done an fpop' This is what I believe they're 'fudging' at the moment. It means they are having to put a linear (for them at the moment) fudge factor based on the angle range. Angle is just one of their data parameters AND is also what caused the problem in the original seti (but there it cause task to be quicker and slower, hence the move to a 'work done' system).
Anyways, will it work over here ? It needs to be tested and to me Rosetta is good project for BOINC to test at ;-)

b.t.w. the reason for the the 'linear fudge factor' in seti-enhanced(beta) is not to stop cheating, but to stop people preferencialy taking the quick jobs (since they give the same credit but in a shorter space of time, although they actualy do the same number of calculations per task) Since you'll have a load of people dumping jobs, to select the quicker one's to accure credit quicker BUT the project (seti) will be left with reissuing or even unfinished tasks/jobs) Well so I understand.

From my vantage point of "minor inter pares ", I dont see why wasting time and resources in the "rewards" aka credit tweaking is worth the time , money and effort.

I just noticed that the recent spike in Wu produced can be traced in large part to a duel by two teams who in the last 28 days were responsible for approximately 37 % of the production share. If you add a third team (who seems to have engaged in the shoot out) we are talking about 50% of the total Rosetta production in the last 28 days. It seems to me that the actual credit structure is motivating them to place more computing resources into Rosetta.

Call me naive but if having for points competition is motivating those three behemoths to produce more for Rosetta, then the project wins. So let the fight for credit continue ( From what I have been able to ascertain the three teams in question are enjoying the shoot out with subtle baitings of each other and a realization that at the end the more they produce benefits more than their bragging rights: Rosetta, the project (Science) wins.



PS : I wonder how many of the participants even notice the credits and rac they have accumulated to even care how they are calculated?

Take it from an analytic, they know.
