Filled up a full 10 day cache, including 8 AP work units. Also: Task duration correction factor 0.015288 I didn't modify that, it was at about 0.17 and with a bunch of VHARs being processed it's dropped to 0.015 :D - Jarryd |

Nice going Hellsheep, now would you be so kind as to send some my way ;-) |

It's so nice to see that the power crunchers actually follow the request from the project admins to decrease their cache "so that more of you can at least partially fill your normal queues before the three-day outage.". (source) Heartwarming, isn't it? Apparently everyone is thinking that message wasn't meant for them, but for all the other crunchers. I wouldn't be surprised to see a 50 to 100 task limit prior to next week's outage. |

(source) Don't be so grumpy - he's just happy to have work. Actually, this time, at least, things seem to have worked out well; the early fixed limit of 20 allowed everybody to get some work fairly quickly (though increased the rate of queries to SETI for work), then opening things up gave those of us with bigger, faster machines our WUs. So we all should be able to get through the scheduled outage OK. Wasn't that the idea? |

Wasn't that the idea? Not with a 10 days cache. Or haven't you read Jeff's post either? Seems like a lot of people haven't done so. Or all must've thought it wasn't meant for their eyes. While in the same thread I pointed to, people are even saying they're increasing from whatever cache they had to a 10 day cache in anticipation of the limit to be lifted. Uhuh, good way to get a limit increase next week, instead of a limit lift. Before you think I say this because I didn't get any, I did... Took me 5 hours to get 31 tasks in on the i3. Blistering high download speeds of 0.24KB and 0.03KB/sec on downloads. I liked those. Something new for my 25Mbit connection to deal with. :) Those 31 probably won't get me through the outage, were it not that I also have 28 Einstein, 2 CPDN and at least 50 Primegrid. I'll weather it. No, I was posting this because it's always nice to see everyone follow admin's request. But y'all seem to think they don't listen to your complaints, so why should you listen to them, right? :) |

Wasn't that the idea? It's not that I didn't listen to them. I actually lowered my cache to 4 days as I stated in the thread. Except it turns out there is probably going to be some work going on at my house putting in new copper cabling and I'm going to be upgrading my router and ethernet cabling at the same time. So i decided since there is a good chance my internet is going to be on/off. I'd download a decent sized cache. I downloaded a 10 day cache at 10-20KB/s down speed. I had to press retry for a few hours but still did it. I just booted up my old AMD machine and it got work also. I don't see why you're complaining since there is still work to download and being handed out. - Jarryd |

Good morning Jord, I'm not a power user but I did increase my cache...all the way from a three day cache to a four day. I wound up empty on the last outage so figured that would get me through. I'm not sure it will though because it looks like the maxed bandwidth caused a few ghosts to be sent. I've got around 50 of them so I'm going to come up short on the outage again. Claggy reported getting a bunch of ghosts too. I've actually only got 117 CPU and 66 GPU WUs to get me through as of right now. I think I'll hurry and increase to a five day cache to try to offset those ghosts. After I get my fill I'll go back to a four day. PROUD MEMBER OF Team Starfire World BOINC |

Good morning Jord, If i counted right i have about 300 Ghosts. >.< - Jarryd |

(source) At least I waited until the morning of the outage to start abusing buttons, thats pretty good for me. I am getting downloads of 30 and 40 Kbps, so looks like I waited for the bottleneck to finish. Official Abuser of Boinc Buttons... And no good credit hound! |

I can understand the reasons for wanting to devote more CPU time to the science development, but they don't have to shut off the entire rest of the project. We know they kept the message boards up. I'd rather they keep up the part that sends out work... |

I'd rather they keep up the part that sends out work... From Matt's post over in Technical News: Data wise, we were able to get back to merging our various spike tables together full bore - doing so while the project was up was causing all kinds of headaches. We'll have to turn the merge off over the weekend, of course. I also was able to do a whole bunch of data integrity testing - it's nice to be able to pull 1 Gbyte of signals out of the science database without the query getting blocked, or worrying about blocking other queries. I guess everything is tied together, to the point where you can analyze the data, or create the data, but not both at the same time. |

Splitting new S@H Enhanced work or assimilating results do involve the S@H science database, so are effectively ruled out during these outages. Because downloads and uploads don't involve either science or BOINC database access, those could remain enabled with the least impact, although at least 3 servers are involved; bane, vader, and bruno. Having forums alive of course needs the BOINC database servers and "data-driven web pages" at a minimum. The more that is running, the more likely something will go wrong and interrupt planned work during the outage, so although they could theoretically just disable all splitters, validators, and assimilators and let the remaining "Results ready to be sent" be issued, I don't expect that.

Question for those who understand these things: are the actual boxes used for the downloads and uploads also running other applications that are needed by S@H during this outage? Even apart from accessing the database, do they just need the CPU power for other things they are likely to be doing? |

Me I could do with a lot less cpu work, As I was down to about 649 WU's for the cpu, Now I'm up to 793 and yes 307 of those are VLAR's that have been rescheduled, way more than I need. The T1 Trust, PRR T1 Class 4-4-4-4 #5550, 1 of America's First HST's |

Even apart from accessing the database, do they just need the CPU power for other things they are likely to be doing? I think it's more likely they need us to keep our hands off the storage. The new system they have is far more powerful that they need, but they need to play with the data base and work with the software which can't be done with us in there. |

Just great. --------------------------- Reschedule version 1.9 Time: 06-07-2010 18:54:16 User testing for a reschedule CPU tasks: 406 (406 VLAR, 0 VHAR) GPU tasks: 796 (0 VLAR, 0 VHAR) No reschedule needed uhmm... and 57 AP units. Wonder which one is closer to the finish line, Quad or GTX260 :-) Who the hell is General Failure and why is he reading my harddisk?¿ |

CPU tasks: 158 (158 VLAR, 0 VHAR) I for sure haven't enough GPUs for 3 days. I have a 4 days cache, tried raising it to 5,6,10 days, but Boinc simply wouldn't get more WUs. Can someone explain that?? |

CPU tasks: 158 (158 VLAR, 0 VHAR) I noticed the same problem, until i reported an AP work unit and got another 400 CPU work. - Jarryd |

I wouldn't be surprised to see a 50 to 100 task limit prior to next week's outage. It has always been the same, from the seti classic days, remember the furore when the backoff was introduced in the setiathome v2x days! It is right and proper for me to get my work, its all them OTHER BUGGERS "hammering the servers" that are stopping me! |
