... Filling in some of the blanks... RAC is recalculated each time credit is granted. Additionally, projects are expected to run a periodic task to decay RAC when there are no credit grants. The sched/update_stats.cpp source for that indicates it does not do an update if the RAC has been changed within the last day, nor if the RAC is below 0.1. The updates for host, user, and team records are all done sequentially. The fact that they are separate calculations means that even under normal circumstances the user RAC is not exactly equal to the sum of the RACs of the user's hosts. Normal circumstances for this project had the update_stats run once a week on Tuesday. That appears not to have happened for the last two weeks, perhaps the executable was on bruno so the cron job fails or perhaps they are using a stripped down config.xml missing that crontab entry. So host RAC for a system which hasn't had a recent validation has not decayed, but for those with more than one host the user RAC may have been adjusted by a validation on a different host. The current BOINC logic doesn't account for defunct hosts with RAC below 0.05. Perhaps an older version of update_stats didn't skip cases with RAC below 0.1 or perhaps some other cleanup script was run sometime. Joe |

... Thanks for the insight to some of the BOINC inner workings. As my AP only systems have had an unchanged RAC since Nov. 7th it makes sense. As that looks to be the same time Bruno went rather sideways. A cleanup process such as that is certainly in the non-critical column. Looking through my older inactive team mates systems. I see hosts with contact as recent as 2012 that have a RAC of 0.00 & hosts with last contact in 2007 with a RAC of 0.10. Perhaps there is another process as you theorized, but it only processes hosts that have communicated with the server in the past N days.

For the first time in over 15 years I am not crunching Seti, this is causing a real panic. |

For the first time in over 15 years I am not crunching Seti, this is causing a real panic. relax, most of us have been out of work for at least 2 weeks now... Surely you must remember Nov-Dec 2012 when Seti was down for weeks too. Patience is all we can depend on ;-) |

I still have a few stragglers on a couple of machines and even picked up a few new ones yesterday. My Einstein rac is higher than its ever been and seti is falling. I've even added a third project Bitcoin and I think I'm posting more in the forums than ever before cause I keep reading them trying to determine when SETI is coming back. I had all old and slow machines back in 2012 so I never actually ran out of work except on one machine. Crunching since 1999. |

I almost panicked. My GPU Bata cache was down to 4 WU and the Status page was all red. Than BOOM the downloads started and my cache filled. Status page is green again. Crisis avoided. Milkyway and Einstein can stay on the back burner. Boinc V7.2.42 Win7 i5 3.33G 4GB, GTX470 |

At that rate we're looking at another 86 hours (+24 for index building), which means Saturday morning (US Pacific time). Sounds like it's time to install a couple of video cards I purchased on Black Friday!! |

Lucky you. I still have to get buy on a onboard APU with only half a gig of memory. Trying to save up for a real GPU sometime in the near future. Waiting for the feeding frenzy in the shark pool to start. |

Milkyway and Einstein can stay on the back burner. You call that gobbledygook fixed? The program names may make sense to him and even to some other people, but most (even those savvy enough to be running Beta) will be looking at long, multiline strings of characters and saying "huh?!"

Milkyway and Einstein can stay on the back burner. Well, http://setiweb.ssl.berkeley.edu/beta/status.php sure isn't fixed .... and http://setiweb.ssl.berkeley.edu/beta/server_status.php isn't updating the daemon jobs as that report is from 12/1 and the task data is from 12/3! I'd say he is working towards a repair. Oh, as to those long names, he took the lazy man's route and printed the entire command line that started the program including option switches [which maybe should not be public for security reasons], not just the program name and instance number. |

Hi Julie, We might want to consider the possibility that the S@H servers & db have decided that once again its holliday season and that they are entitled to some time off:-) This kinda reminds me of 2012 around this time of year there was a significant outage as well. Perhaps we should be thankful that S@H only decides to holiday every 2 years or so:-) Regards, Cliff, Been there, Done that, Still no damm T shirt! |

Hi Julie, I think the db might be working overtime with all the work going on in the background to move the data into a new table. At least I imagine it would be more than us poking it x number of times a second.
