Okay I have two devices, and they dont make sense
1st Device 2.1ghz AMD Athlon 1.5gigs of RAM 5gigs allocated space Total Score for Machine 191 2nd Device 3.0ghz P4 w/ HT 1.0gigs of RAM 5gigs allocated space Total Score for Machine 170 Now why is my AMD producing more points/results per unit time than my p4 which should in theory be faster. If i am using a machine it is always my AMD, the p4 has nothing running on it except WCGrid at the moment. |

If you notice in the Device Information under Memory Performance,The standard the we are measured by is 384 Meg
----------------------------------------So I.5 Gig on your AMD gives you a score of 391 And 1. Gig on your Pentium P4 gives you 267 This difference of 124 gives you an overall performance boost All the calculations are weighted based on the comparison device being 100, arrived at by adding processor, memory, storage,and network together to arive at 100 The additional 500 Meg of memory is enabling your AMD to out perform your Pentium P4 Incidentally these ratings are re-calculated each time you download a new Work Unit So if your machine is sitting idle with the exception of WCG running, then you will get a good overall score, however if you are doing a system intensive task at the time of Uploading your results your rating will drop for that work unit and readjust at the next upload of a completed work unit I hope this help to answer your question [Edit] On Stares advice as I had the figures transposed Regards [Edit 2 times, last edit by Former Member at Jan 6, 2005 10:25:08 AM] |

So I Gig on your AMD gives you a score of 267 And 1.5 Gig on your Pentium P4 gives you 391 Of course, Graham meant the other way around as the 1.5Gb is on the AMD and the 1Gb is on the P4. You could even get more points if you allocated 10gb storage to each device. It won't actually be used but you will get credit for it. |

I was wondering about this too. I've got a amd athlon xp 1500 with 1.5 gig of (I think it's ddr) ram versus a pentium IV 2.4 ghx with 512 gig of (rambus) ram, both setup with 6 gig of hard disk allocated to the project. My amd is also scoring higher than the pentium. Not that I really care, I was just kinda surprised by it.

This discussion gets confused. Your points are calculated based on Memory, storage(disk space), communications speed(Network) and processor. These calculations vary all over the place.
----------------------------------------Your communications speed is determined by the amount of time for the agent to communicate back and forth across the internet with the servers. Your storage is determined by how much you have "allocated" in your device profile. Your memory is fixed by the amount you have physically in your computer (this is constant -- unless you open the covers and change it). Finally the "Processor" score is determined by a little benchmark that is run with each work unit that you get. As such it can vary dramatically depending on what else is running on the computer when the little benchmark is run. So two of the four variables in the computation of points vary with each work unit. (the Memory stays the same till you change it and the disk space allocation stays the same till you change it). Most of these discussions eventually get around to some perturbation of which CPU is faster ... yours or mine.  To try to help take some of the mystery out of this problem, I have compiled the results of hundreds of reports on "Processor Scores" as reported here on the WCG and on the Grid.org (which rate the processors in an identical fashion). You can see the results of this compilation by clicking Unofficial Processor Ratings Hope this helps ---------------------------------------- [Edit 1 times, last edit by RT at Jan 15, 2005 5:28:25 PM] |
