Could it just be because we got the scheduler to correctly send out SSE2 applications, which are over twice as fast as the ones without SSE2? Unfortunately, the results scroll from the task view in very short order. The ATI GPU WU's seem to be generating a normal 2.38-ish credits/second for my HD5870. (Absolute max of 205,632/day possible.) The 9hr-long 0.45 SSE2 "de_separation_82_3s" WU that just got verified was awarded a normal-looking 213.78 credits. The two N-body WU's I can see got considerably less credit proportional to run time. (To my recollection, 0.19 was also turning in WU's in the 9-10hr time frame so is the SSE2 faster?) My RAC is now 232,600 and still climbing. So where is the extra 27,000 credits/day coming from? Even if both machines running CPU WU's were monopolized by MW, which they are not, they couldn't possibly do more than 85 WU/day. |

Thanks for responding and getting stuck into this Travis - MW reputation is taking a hit right now, understandably if you take a look at the total credit awards for each project on BOINC Stats - MWs suddenly goes through the roof three days ago. The credit award is stable at the cruncher end, time taken is normal, and credit award as seen in the account summary for individual WUs is normal. I have a feeling its when the summary of awards is presented to Stats thats its going wrong. For some reason despite normal awards for each individual WU, our account summary page Total all show inflated award totals that are reflected in BOINC Stats, and have no similarity at all to the actual crunching that happened. Its by the same proportion for everyone, around 2-3 times the actual award. The latter is consistent, so whatever it is, it should be easily fixable in that it appears to be a single variable thats inflated by one multiple somewhere in the system that calculates the credit summary totals for the account pages and Stats pages.

One thing I've noticed: "Milkyway@home ATI GPU application version 0.20b (Win64, CAL 1.4) by Gipsel" You should update your GPU app to version 0.23 for Win64 and your progress bar should be fixed. I saw only a small increase in credits for a short time and at the same time the number of pending WUs went down, so that roughly fits together in my case. Since the number of pending WUs are stable around the actual lower number, my RAC looks normal again. |

Its when the cruncher account page summary total is calculated. I just watched three WUs being reported, individual WUs were shown as normal awards, however my personal account page summary total instantly incremented by just under triple the individual awards. That would make sense if the BOINC Stats totals Project generated xml page is compiled from account page summary totals, and explain why the Project Total has gone through the roof. EDIT: Verified, just watched another four go through. Account summary before update: 29,734,767 Account Summary after update: 29,737,405 Difference = 2638. Four WUs went through each @239.8 individual award, the account summary total incredmented by 2638, just under three times reality. So its definitely in the code that calculates account page total summaries. Regards Zy |

It's funny. I note some folks have dropped other projects like a hot potato and come running here to get some of the credit bonanza! A great way to get more volunteers! Make hay while the sun shines! |

rofl - Chain the door and dont let em out until they have done extra crunching up to twice their normal crunching as penance :) Regards Zy |

Tried to verify Zydors finding. 3 WU's adding up to 693.38 credits difference in total credit: 1840 So it's the same here. Makes a factor of ~2.65 Seems my mix of MW, Collatz and DNETC was hiding most of it:) |

Travis has nailed it - he just posted on the News Forum, looks like its back to normal now. Regards Zy |

They were running fine after the daemon update, I suspect he is probably clawing back the erronious extra credits Regards Zy |

Well, we always knew it wouldn't last, it was clearly a temporary bug that has now been fixed. But it was interesting for a while to sit back and watch people react. I could have got 4 more machines running but I didn't. Yet we hear of people ditching other projects and rushing over here to jump on the bandwagon. Well, Boinc has always had its ambulance chasers. I wouldn't agree that the MW reputation is getting a hit. Most people would have realised that this was just a blip that would get fixed, which it has. OK peeps, Defcon 3, back to boring normal. :-) Don't drink water, that's the stuff that rusts pipes |
