I realised that when Grant mentioned Beta earlier. Been too used to seeing 50 Beta & 100 Main. It seems that AP flood upset the applecart. All the MB will be completed by this evening & the AP by the weekend. |

Results Returned in Last Hour has hit 237,593 and the RTS is practically empty (30K). The system is still up though. It is 7am in California, so hopefully soon someone will notice and throw us an Aricebo dataset , if they have one. Yeah. This is consistent with my personal surge of 100s of 10 sec WUs (apparently too many spikes) that I have been getting on both GPU and CPU on 2 crunchers (out of 2). So maybe NOT just me... My pendings and validated have gone way high in the last couple of days. More than doubled. Watch for many more WUs being sent to users possibly causing congestion on the outgoing data path from SETI???? |

Results ready to send 0 0 205 0m This is a problem |

Results ready to send 0 0 205 0m Definitely a problem. On the bright side, the splitters are still splitting, but just aren't keeping up with demand. The big question is how many of the files to split are garbage. Once we work through the junk and get some good WUs then the system can recover and we can all refill our caches. So far the Results out in the Field is falling slowly. |

Just looked at my hosts and found the big iron empty. Checked the RTS and it is empty. Seems like all we've had to crunch for several hours are noise bombs. Seti@Home classic workunits:20,676 CPU time:74,226 hours A proud member of the OFA (Old Farts Association) |

It looks like the elves in the lab loaded some new BLC01 files. Hope the splitters move to them soonest and flush out the noise bombs. Seti@Home classic workunits:20,676 CPU time:74,226 hours A proud member of the OFA (Old Farts Association) |

Hey - I have noticed many WUs recently that process in < 10 secs. Like dozens or hundreds/day, both on GPU and CPU. Are these the "noisy" WUs referred to above? Are they the variety that has 30 spikes detected and then dropped by the app(s)? . . Yes! Stephen . |

Still getting noise bombs. . . About 80% to 90% it seems ... need to preserve Arecibo VLARs to have any hope for the outage ... Stephen :( |

I'm hoping the BLC23 clear out of the RTS buffer overnight and we can chew on a steady diet of BLC22, BLC01 and Arecibo tasks. Seti@Home classic workunits:20,676 CPU time:74,226 hours A proud member of the OFA (Old Farts Association) |

We have to hope there is a good supply of Arecibo tapes to keep the Arecibo VLARs coming to slow things down and let the RTS refill. Hopefully the remaining blc22/blc23 tapes will split and clear before the outage so that maybe the Blc01 tapes can start to come out and are less noise prone. Stephen :( |

Well Green Banks should not have any noise. IMO the noise is probably a hardware issue. We will never know. |

It's in the form of the massive radar pulses from the dish when active. At least they get blanked automatically and we never see them except for the AP tasks. Agree for Green Bank being in a noise free zone, it must have been hardware failure of some kind.

Well, things did get interesting overnight. Looks like the return rate just missed out on a sustained 300k/s, at least it's now dropped to "only" 190k and the splitters managed to get going again & are mostly keeping up with the present demand- occasionally getting ahead & re-building the Ready-to-send buffer, then dropping behind & the buffer drains again. And while the deleters managed to catch up & get back on top of the work load, the Assimilators appear to have given up- the present backlog is just short of 1 million. Interesting that after all the VLAR Arecibo work we had been getting, now we've got lots of quick GBT jobs, we're also getting lots of shorter running Arecibo work. The perversity of nature.

Then I suggest you take the opportunity to buy a lottery ticket :). I am having the opposite results here. On all 4 machines. Stephen :( |

Well Green Banks should not have any noise. IMO the noise is probably a hardware issue. We will never know. . . Even the best locations can experience RFI at some time. The earlier tapes in the current two series (which cover the same observing period) were pretty good and noise free, but at the tail end of the series both series seem to have experienced a rise in RFI.
