I don't know if anyone else has noticed this, but over the last couple of months my pendings are getting ever bigger in numbers. About 40% of everything I crunch is going in the pendings list. Yet some of my wingmen are running i5's and 970 cards and are regularly contacting Boinc. So why aren't they reporting work? Like wayward kitties, pendings always come home eventually....... Meow.

Your pendings aren`t higher than mine. So nothing suspicious. With each crime and every kindness we birth our future. |

Ok, thanks for the replies. They just seemed a lot higher that what I remember themto be. First time I've ever run two cards in one rig, was rather hoping to see the RAC go up a bit quicker. No matter. The faster you turn the work around, the higher your pendings will be. They will stabilize at some point and hover around that value. "Freedom is just Chaos, with better lighting."

I don't really pay attention to tasks in pending or inconclusive . I really only find In Progress, Valid, Invalid, and Error useful SETI@home classic workunits: 93,865 CPU time: 863,447 hours Join the [url=http://tinyurl.com/8y46zvu]BP6/VP6 User Group[ |

High Pendings tell me that I have gotten ahead of my wingmen (on average), so I know that they consist of more older, slower machines than the usual mix. That's all...but I then know I WILL get a bump in credit when they show up, to offset the current lower credit as the current Ps accumulate. |

No matter. As kittyman pointed out, the more work, and the faster you do it, the higher the number of pendings will be. Generally Pendings are up to 1/3 of the All number. For Petri All 17,237 Pending 5628 For my i7 All 2,194 Pending 817 My C2D All 679 Pending 242 The more work you do, the higher the All number, and the higher the Pending number. RAC is a lagging indicator- putting a new system online it takes 6-8 weeks for RAC to settle. Adding another card, or just upgrading a card, it still can take 6-8 weeks for the RAC to settle around it's new value. And that's without changes in the work mix (GBT v Arecibo, amount of AP work if you do that), let alone Server downtime above & beyond the weekly outage. Grant Darwin NT |

Generally Pendings are up to 1/3 of the All number. State: All (440) · In progress (85) · Validation pending (161) Not on the box I run Seti on |

I generally find myself running higher pendings than valids, but not right now it seems. 3.5 hour turnaround All (7945) · In progress (717) · Validation pending (3439) · Validation inconclusive (175) · Valid (3614) 12 hour turnaround All (2170) · In progress (300) · Validation pending (906) · Validation inconclusive (35) · Valid (939) ... typically this one has lower percentage of pendings. |

Generally Pendings are up to 1/3 of the All number. ? 2.7 is more than a half, but less than 1/3. And it's closer to 1/3 than it is to 1/2. The faster you return work, the higher pendings tend to be, the slower you return work, the lower pendings tend to be. Hence my use of "Generally" and "up to" and "tend to". Grant Darwin NT |

My pendings are also high atm. Luck of the draw with wingmen, I guess...sometimes I have to wait for time-outs, and then the WU gets sent to a very slow computer. Oh well...all WUs will clear out sooner or later ;-) ...Ghia... Humans may rule the world...but bacteria run it... |

I've noticed a big drop in RAC, not just for myself but for my group. I'd been in the high 20k range and this week I'm dropping more than 10k points and so has the guy that usually has the same numbers as I do, the rest the group is dropping by the same proportion. I also have the 1/3 pendings folks say is normal. I usually only look at my RAC and our small group's active list now and then but I can't recall something like this happening before. I was into the gold badge range last week or the week before. |

I can't recall something like this happening before. It's happened before, it'll happen again. For quite a while, we had mostly Arecibo WUs, which take less time to process and give more Credit than GBT WUs. Over the last few weeks the percentage of WUs have moved over to more GBT than Arecibo, so longer to process and less Credit. Add to that the current batch of GBT WUs are the longest running yet- so even less Credit than in the past with a similar mix of work. At some stage in the future there will probably be a drop in GBT WUs, and a corresponding increase in Arecibo WUs and RAC will rise again; till there's more GBT WUs once again & RACs will start to fall, once again. Rinse and repeat. Grant Darwin NT |

It could be said could it not, that all work supplied from Arecibo or GBT is still Seti work at the end of the day. So why is there different credit awarded? Credit New. Grant Darwin NT |

Grant got it in one The reason being that CreditNew is not properly calibrated to cope with the different sources of data. It also has flaws that make it difficult to maintain such calibration. A "proper" credit granting system would grant the same amount of credit on a given processor on a particular computer for a benchmark task last year, this week and next year. Because CreditNew tries to continuously re-calibrate itself it will not do that. Add to that the differences in the actual data the amount of calculation required for the two major sources (and effectively six task types) it is hardly surprising that the amount of credit per hour on a given processor varies so much. It is not beyond the wit of man to come up with a credit system that would cope with the six task types and award credit consistently, based on the actual task (server side action), not on the run-time of the computer (client side action). CreditNew is predominantly a client side process, with a bit of "interfering" from the server.....

Not be afraid ! How faster your run task, how slower the will be validated (not everyone run very fast and/or 24/24, 7/7). My turnaround is less than one day. At me : all : 1615 in progress : 600 Pending : 538 (and always above 500) |
