Hi,
This is totally unimportant, so if I don't get a response, it's no big deal. I noticed that the WCG agent reports my Pentium M 1.2 GHz processor as a Pentium III 1.2 GHz processor. I have a desktop PC with a P4 1.6 GHz processor and 512Mb RAM, but my Pentium M 1.2GHz runs circles around it (i.e., much faster than my desktop). It has seemed faster even when they had the same amount of memory and now that I've upped my Pentium M machine to 1.1 Gb of RAM, it never seems to have to pause for swapping to my hard drive. Is there a reason that the Pentium M is rated as a PIII rather than as a P4 or higher? I think that all the actual reviews of the Pentium M that I've seen have rated it's speed as higher than the equivalent clocked P4 Mobile (I know that's not the same comparison as the standard P4) processor. Again, this is unimportant since my PC's are both doing work and I don't really care about the actual points or ratings, but I'm just curious if my perception of the Pentium M is incorrect. Any thoughts? Andrew |

Hello alin84,
The Pentium M is a second-generation Pentium III. So the old detection routines that distinguish between the Pentium IV and the Pentium III name it a 3. The new Core 2 that is replacing the Pentium IV is a third-generation Pentium III, except for one section of the chip that has been adopted from the Pentium IV and upgraded. The UD client does not have a modern CPU detection subroutine. Lawrence |

Thanks, Lawrence. That makes a lot of sense. Obviously, there's no way to know about future processors.

Hi,
My old 1.6 GHz Pentium M laptop reports itself as similar. Even if you do care about the points, it doesn't matter that it is incorrectly identifying your processor as the UD agent will be calculating your points based on a CPU benchmark, amongst other things. Rob |

Hi Rob,
Actually, what had kind of caught my eye was that the agent had rated my processor as something like 70 or 80 compared to the standard, which I thought was based purely on processor speed. It seems to have changed it to a rating of 113 today, so maybe it fluctuates. I had followed it for about a day while it was at the 70/80 mark thinking that maybe it fluctuated based on my own cpu usage, but maybe it does a ranking whenever it starts / finishes a particular task. Thanks, Andrew |

Hello alin84,
Yes, the UD client runs the benchmark every time it downloads a new work unit. |

Alin84,
----------------------------------------The cause of the fluctuation is the present load of your machine as u surmised....if u r heavy word processing which is at normal priority as is what level UD.exe is running, than UD.exe only gets part of the CPU ticks during the benchmark which happens at end of each WU. If u set UD.exe manually to 1 priority higher than normal in taskmanager, it gets more or less the exclusive CPU time to perform its benchmark....your word processing markedly slows down.....lasts a minute. Be warned though...if u do that and start watching the graphics, u pay the price....the science slows down similar to the UD screen saver effect. Otherwise, UD.exe does little to nothing. Since my last boot 6 days ago, it has accumulated 7:33 minutes of CPU time....insignificant. PS my benchmark is extremely consistent on 172/173 by this method. ciao
