After two days of running these new E5-2697 12 cores and seeing app 200,000 WCG PPD I suddenly see the point award dropping from app 24 PPh to close to 10PPH/ per core..
----------------------------------------All on the FAAH project running win7-64 ultimate Discussed at the end of this thread. Thanks! https://secure.worldcommunitygrid.org/forums/wcg/viewthread_thread,35702 ![]() [Edit 1 times, last edit by Movieman at Oct 30, 2013 3:31:50 AM] |

This image shows the issue. Look at the claims at the top vs the claims at the bottom..WAY off of what they should be,,

Movieman, this could be to do with the averaging that goes on in the qorum/replication. as in if you claim 50 the other machine claims 50 you both get 50.
----------------------------------------However, if you claim 50 and the other one claims 40 you get 45 each (ie [50+40]/2)... I've seen this with some of my wu's especially on faster machines. this may not be the reasom, but it may...

I checked this and no, this is single. IE: No wingman. I also think you missed what I was saying. On these WU my machine is claiming app 10 WCG points per core per hour vs the 24-25 it was claiming before. I "beleive" this to be a function of the WU itself not my machine. Then if any more proof of this is needed is it credible to beleive that this machine which for all reality has the top cpu's money can but, 24 cores at 3226 MHz, IB arch, is only getting what a decent 6 core would get? Just no logic behind this that I can see and thats why I asked for help here.. ![]() [Edit 1 times, last edit by Movieman at Oct 28, 2013 7:40:07 PM] |

I am not Lawrence, but I can offer another observation. I too have noticed this with my machines running Windows, and not only the ones running Linux. I have a q6600 running Vista and it gets very poor points, about 7 to 9 points per hour. At one time it was doing about 15 to 18 points per hour. I have done nothing different with the machine so I don't know why the difference. On the other hand I have an AMD 9150e with Win 7 which has consistently done 11 to 15 points per hour. It seems unaffected by whatever is affecting the Linux machines and the Vista machine.
----------------------------------------I agree with you that something is amiss. My first thought is I do not think this has to do with your machine but with the way the server(?) is awarding points. But, after looking at your times, I am discarding this notion.Your times for these units should be much faster with the kind of horsepower you have in those processors, even given the Windows penalty you are paying. I know the units are inconsistent with times, but there seems to be a bottleneck someplace. The only thing I can think of right off hand would be to cut the hyperthreading and see if there is a difference. Then try cutting the number processors in half and see if there is a difference. If the WU's show a rebound in how they perform, then you need to start looking elsewhere for the bottleneck. If there is no rebound, then maybe it is a software/OS problem. At the moment I feel like I am shooting in dark. Good luck. Cheers

Cheers Joe: You make good points except for the fact that the first 2 days I ran this same combination I was getting an average of just over 200,000 WCG PPD. Nothing else changed at all and I mean nothing with the exception that it looks like a differnet batch of FAAH WU are being done. This is why I think there is a flaw in those WU..Then add in that I ran a 10 core E5-2670 V2 before this, same arch, and tthose got app 140,000PPD at 3047MHz..There is no issue on this end that I can see and shutting down HT wouldn't give me the info I need and if anything would skew my own numbers the wrong way.. ![]() |

Well, I have no qualifications to justify a response, but I'll dive in with some observations of my own anyway

But the main point is: new boxes/apps tend to claim high at first and then come down. This seems to be what you're seeing. What do others think? |

I didn't know whether it was the server or client that made the "claim" 2) Client isn't new, has over 35 million points on this install and runs just the FAAH WU so this is a moot point 3) read my response to number 2, makes this moot also 4)same as above, this is a consistant machine so again, moot point BUT I do thank you for bringing up these points. The exchange of info is how we all learn! ![]() |

Movieman,
In your first post you said "After two days of running ..." so I assumed that that was all the time the box (installation) had been up. The levelling process takes a number of WUs to sort itself out, so it may not be exactly time dependent. And I certainly don't know the details, but I wouldn't be surprised if it's based on some statistics which are gathered every 12 or 24 hours. Either way, my own feeling is that two days is actually pretty quick to sort out the levelling. If I misunderstood I'm sorry. And I certainly have no other explanation for what you're seeing. |
