I have a P4 2 GHz processor in one of my systems. The comparison device in the 'device information' section of the wcg agent is a P4 1.5 GHz processor. When I first installed wcg, I received the correct processor rating of 2/1.5 x 100 = 133. After completing a few work units, my processor rating has now changed to a 56. If I understand the points system correctly, this means I am processing work units with a 2 GHz processor, but my artificially low processor rating is dropping the 'overall' rating of my system, and I am earning fewer points for CPU time than I should be. I have a 2nd device with a P4 2.2 GHz processor, which has maintained the correct rating of 2.2/1.5 x 100 = 146. Both devices are using the same profile. Any explanations/suggestions?

??? Well . . . The Device Information box on the agent has 5 subheadings:
1) Overall (default) 2) Processor 3) Memory 4) Storage 5) Network Click on each and compare the resulting scores for your 2 machines. Perhaps this will suggest an explanation. |

The scores for the other categories correlate, which is why my processor rating is a mystery. In general, the scores for individual categories are obtained by taking the ratio of the characteristic (processor speed, allocated memory, etc) of your device to the value for the same characteristic of the comparison device. The 'overall' score is a weighted average of the 'processor', 'memory', 'storage', and 'network' categories. This 'overall' score then weights your CPU time when calculating points. Since my processor score is a 56 when it should be a 133, my 'overall' score is low, so I'm losing points. More importantly, I have to wonder if the miscalculation of the processor score might be a symptom of a more serious problem. At the least, it appears to be a glitch... I wrote to tech support; if they respond, I'll post it.

Rick, thanks, I read the following: "The software periodically runs diagnostic tests to establish the processing power of your hardware configuration. These values are averaged and then divided by the CPU-Power value of World Community Grid Comparison Device...."
Does this mean my processor is performing at average of 840 MHz, not 2 GHz (.84/1.5 x 100 = 56)? Why did it consistently score 133 (2/1.5 x 100) for the first few days? Why does the 2.2 GHz processor in my other device (which has been running wcg longer, and which serves as my primary work station) consistently earn a processor score of 2.2/1.5 x 100 = 146? Does the diagnostic test measure only the amount of processor power being used by the wcg agent? |

Same problem here. For a couple of weeks I was showing a proper Processor value for my AMD 0F48 2.0 GHz processor (compared agains the Intel Pentium 4 1.5 GHSz). Now it shows a value of 1. Quite a dropoff :-). What's up with this?

I also have this problem. On one system I have a Pentium 4 1.5 Ghz which is the same as the reference processor and therefore should get a score of 100, but for the last week or so it has been given a score of 78. My overall score is 117 for this system, so it would not be related to the cap of 200 for overall score.
What is going on here? Can someone from Tech. Supp. explain why we do not see the full rating for our CPUs? |

Can anyone explain why a fixed componant can change it's relative value in this way? This has changed my overall rating for this machine to 121 (from 117). Bizarre! |

What I think is, if WCG is running, but getting starved of your CPU cycles a lot of the time, then it ratchets down your CPU rating accordingly.
I have this installed on 3 machines. One machine sits in the family room in front of the TV, and the one the family uses. It's a web surfing machine, and doesn't do much but WCG. it's CPU rating barely moved at all. My second machine is my work laptop, which is dropped 18 pts lower to a rating of 182. My third is my Opteron that I have been playing Neverwinter nights with, and that one has lost a lot of its CPU rating from what it started at. I kept WCG on while playing, just in case it could sneak a few cycles in. I got my rating to go back to its original rating after I beat the game and stopped playing for a while. That's my experience, though I should read more of the site. however, my lunch break is up. ;) ~B |
