This is question is directed to David Autumns (or anyone else that can explain the results to me)
David, Thanks for the explanation of how points are calculated, I had wondered by was never certain. Two things do not make since to me. I have been apart of the grid for almost two months now and since I have increased my storage to max, my overall measurement has remained stable at 179. Additionally, the points per CPU hour have also remained stable at 33.94201. I ran the points calculation you provided in a "Start Here" thread. My device information shows the following information Processor 183 Memory 267 Storage 196 Network 100 Based on the weighting in your post, I come up with an overall score of 179.75. When I divide this number by 5, I get 35.95. Do you have any idea why the difference between this result and the points per CPU is occuring? Second issue. Your point calculation post indicated - "After each Work Unit is completed your PC is benchmarked/compared against the 1.5GHz Pentium (a 1.5Ghz Pentium having a value of 100 ) so a 3.0Ghz Pentium would on average get a score of 200 for example. " I know that you are performing some kind of speed check, but the processor in this device is an Intel Pentium 4, 3.2 Ghz. Based on a straight ratio, the processor's score should be 213. This is a new computer with little else on the machine. Any thoughts on what is causing this 15% under performance? If there is a problem with the processor, I need to talk to the organization that sold it to me. Thanks for any information you can provide. David McCartney |

Are there 10 GB free on the drive/partition where the client is installed?
Some CPU scores have been posted here: Show your processor score! http://forum.grid.org/phpBB/viewtopic.php?t=4835 Is Hyper Threading turned on or off (in the BIOS)? Does the CPU have a Northwood or Prescott core? The Northwood core has a slightly faster FPU if I remember correctly, whereas the Prescott has the larger cache, which isn't needed for this purpose. |

Hi David McCartney.
----------------------------------------Thanks for your post as I wasn't sure when I wrote the post on exactly how to work out points per hour from overall rating you will note that I wrote "just over 5". The thing is that the benchmarking of your cpu does not give "exact" results as you may be doing a processor intensive task at the end of one work unit and therefore when your cpu is benchmarked it will return a lower score for that work unit than normal. So all of the figures have a margin of error in there. Your figure works out as divide by 5.27 but due to the problems detailed above each member will be slightly different in this respect. So "just over 5" is there or thereabouts. n.b. the 179.75 is turned into an integer value i.e. 179 (as displayed in your overall score) On you CPU score you do seem to be running a bit slow I have a 3200+ Athlon which AMD claim is equivalent to the P4 3.2Ghz and I'm scoring about 216 for the processor on average. I would investigate the BIOS on the motherboard and see if there is a later one. I would see if there are any later motherboard drivers available also I would check the timings on the RAM fitted. If your BIOS is set to Optimum Settings then maybe it's time to find out what would happen if you set them to "Aggressive" There might be more in that processor than you are experiencing at the moment. Have you checked under task manager (right click on your Taskbar and select Task Manager) to see that there are no rogue processes running taking your CPU power? Keep your PC clean with Anti Spyware software your PC may have been Hijacked and these additional processes are sapping your CPU's capability. Post back and keep us up to date on your findings Regards Dave  |

David
Should the Hyper Threading be turned on? What are the positives and negatives? Where do I go to check if the BIOS is set to optium? Current BIOS Version/Date Dell Inc. A02, 8/23/2004 Should it be updated? What are the positive and negatives? I do not feel real comfortable about just change the system. Thanks for any assistance you can provide David McCartney |

David.
----------------------------------------You are going to get different answers to the HT question. I find turning it off does not help anything and actually slows you down. So I leave it on on all 9 of my P4 HTs (all Dell). A discussion of HT is here Check Here for updates to your BIOS. If Dell does not have an update, I would suggest you leave it alone. You should get free support since your system is less than one year old. CrossCheck your processors with others of its kind here I see 3.2Ghz processors reported at 215 to 220 so if yours is reading 183, it is underperforming. I expect that there is something else in the machine that is eating up processing power. From David Autumns Have you checked under task manager (right click on your Taskbar and select Task Manager) to see that there are no rogue processes running taking your CPU power? Keep your PC clean with Anti Spyware software your PC may have been Hijacked and these additional processes are sapping your CPU's capability. Good Luck  |

The ability to turn hyperthreading off is very peculiar. I think it is included for reasons of human psychology. There are rare combinations of software that run slower when hyperthreading is enabled, but no ordinary user is going to be able to notice that. Hyperthreading occasionally allows a big speedup. Usually it just makes a small speedup, not particularly noticeable.
There seems to be a reaction against it by many people who look into it, because it disappoints their expectations, but there is no logical reason to turn it off. RT has got the right idea. There is a rational reason for programmers to ignore it. To really take advantage of hyperthreading takes some finicky programming that will not carry over to the coming multi-core cpus. Unless the program will really benefit from it, it makes sense to delay and concentrate on other matters. |

Updated BIOS to A03 from Dell With in BIOS, factory default setting is OFF for hyper threading. Made sure it was on. On Task Manager WCGrid normally shows 50%. Drops to 49 every once in a while at same time explorer goes to 1%. Will see how it goes. Thanks for your thoughts. David McCartney |

David. Sounds if you are in good shape then. If Rosetta is getting 49-50%, then you should be cranking them out about as fast as that machine can. Of course it depends on FSB Memory speed, disk speed yada yada yada ... but from what I can tell you ought to be doing well.
----------------------------------------Hopefully you will begin to see Processor scores in the 215+ range (when it runs the benchmark while nothing else is running). Let us know over in on the processor score thread if you don't mind. |
