Why is the maximum overal performance 200?

Hello,

I think I understand the points system. But why cannot I get more than twice points against the comparison device? Why is the overal performance capped to a maximum of 200?

cool Re: Why is the maximum overal performance 200?

We copied the 200 point maximum from a well established grid at http://www.grid.org without changing it. My guess is that they decided on the limit to encourage participation, since only a few members will have the newest, fastest computers. But that is just my personal guess.

Re: Why is the maximum overal performance 200?

I believe that the limit of 200 should be re-thought. Back when it was set, the biggest processors were 1.5Ghz P4s. Obviously we have processors that run more than twice as fast. Likewise we have disk space and memory spaces more than twice as large. Communications is another issue but in some respects is similar.

I don't want to give the impression that I like the points calculation. I don't in that it lets things other than CPU power have a disproportionately large effect on the overall calculation and subsequently on points.

I believe that this will introduce an anomaly in processors used in the project. Putting one of the newest and fastest machines to work in this effort will not be recognized. As I have said before, each of the measurements that we keep track has a fundamental flaw. "Task time" rates Pentium II computers the same as the XP3400s. "Results" biases things in that there are great variation in work units from time to time and from month to month. "Points" gives a disproportionately large influence to factors such as memory, storage and especially communications based on their contribution to the overall production of work.

That having been said, I think the WCG should re-think the years-old decision made by UD to limit the overall figure to 200 as it has outlived its usefulness and will now serve only as an artificial restriction to the annoyance of a growing number of contributors. Regards all.

Re: Why is the maximum overal performance 200?

Hi RT
Was waiting for another post before dropping this one in here.
I didn't expect to see the same thing in better words.
Heres mine anyway LOL. (unchanged in editing)
I have to make a point that the values or Point Ratios were established Years Back. Before
I started crunching for UD; before the GRID. Back then the Top of the line PC was a "1.5 P4.".
At My start My old 1600MHz AMD did allot better!
I think that the Scoring Needs To Be Addressed to bring it up to date with the fact that
this work brings in a proportionally large amount of Nerds with Rocket Machines.
The "Legacy Point Ratios" can't deal with the modern realities,,,,
This I hope will be assessed and adjusted by the new owners to better attract more of us Nerds too!


Too Funny!
