Hi Everyone. I am a real "newbe" here but have been involved with the Grid.org effort for a few years. The technology of this effort (WCG) is very similar to that being used over at Grid.org. On that organizations forums was a thread about processor scores.
----------------------------------------I took all the processor scores as reported by the members and put it in a spreadsheet and made that information available on the web for everyone about a year ago and have kept it updated since. I believe that these reports represent, in a crude sort of way, what people actually experience with the various processors, usually under less than totally optimal conditions (read "real world" conditions). As such, these stats might be useful for people to use when picking out their next cruncher or if they are trying to see if their current cruncher is running about like the others of its kind. Please feel free to visit that page and see how your processor compares to others of its kind. If someone wants to start a Thread over here of "Show Your Processor Score" I will add that information to the web pages. For the time being the information is located Here I would also be pleased to get any feedback ... apart from saying "so and so was lying" ...or some such. On that point, I just report what people say without judging. ---------------------------------------- [Edit 1 times, last edit by RT at Dec 24, 2004 3:15:49 PM] |

Well that IS some nice info you got there
 As expected the AMD processors score better then the Intel ones. Altough the use of hypertrading isn't kept in mind. I think there is no need to open a new thread to gather more cpu scores as these are enough i think! But i may come handy when the UD(WCG) agent would start to use hypertrading! I think it would give a boost to the intel of about 1.4 |

I think it would give a boost to the intel of about 1.4 As has been discussed many times before, hyperthreading has almost no impact on CPU intensive tasks such as Rosetta. The CPU is being run at 100%, regardless of what the Task Manager reports. In fact, it's even possible HT could slightly harm your scores as the CPU might thrash trying to run two threads at once. I have no measurements to back this up mind you, but there are many benchmarks where HT reduces performance. This may very well be one of those cases. In either case, the effect of HT should be very minimal either way.

I'm sorry to start this discussion again. But look at programs such as D2OL, TSC, Climate Prediction, ... . They all are cpu intensive and they all give a speed increase of about 1.4. Altough other projects like distributed.net and Prime95 does have practicly no advance. But i think this project does more belong to D2Ol and the rest...
Correct me if i'm wrong |

I have no measurements to back this up mind you, but there are many benchmarks where HT reduces performance. This may very well be one of those cases. In either case, the effect of HT should be very minimal either way. My experience tells me a couple of things: HT being on or off makes no perceptable difference in the CPU score and as far as I can tell the processing time for a work unit. It does give the user the ability to do more word processing or browsing without significantly affecting the agent though. This is because it can process scalar instrucions simultaneously with Floating Point (read agent). Bottom line is that I recommend that HT be left on. I have 10 P4 HT machines and it is enabled on all of them even though most of them do nothing but crunch. On the other point, New processors are coming out all the time and I for one cannot wait to start getting reports on the dual core chips as well as some hopped up AMD A64s and those new Intel P4s. So... Folks any reports you send to me that include CPU Score, Processor type, etc...you know what I need... not overall score etc. I will add. Thanks everyone and have a great holiday season. |
