I agree with Grant, splitters are just too slow at moment. Results received in last hour is above 100.000 all time, so Current result creation rate should be at least 28/sec to keep it even. Yes, I did read Matt's technical post, and I know they are concentrating to get GBT tasks on-line. I just should write that I hoped and wished they have more manpower and time (and money) to solve issues like current MB splitters are too slow at this moment. |

I see the splitters are still not up to the task. Now they are, somehow. RTS is about 84K, and it has been raising since last 6 hours. I think that AP splitter running is helping MB splitters again. |

I agree that that seems to be true. What I have noticed is that high MB production and having the replica running don't seem to coexist, one can either have one or the other but not both. At least it would appear that way to me, of late. Member of the 20 Year Club |

I got one! I got an AP! I haven't seen one in a long time. Congratulations on your milestone! Keep on crunching. Member of the 20 Year Club |

Splitters are as simple as 1,2,3 - When shorties are mainly being split RTS goes way down, We are now back to mainly VLARs being split and RTS goes up. 1,2,3 = 1. Shorties go down and 2. VLARs go up 3. Normal AR's go sideways:-) I was getting mainly shorties ie 30 minute AVX now I have mostly VLAR's taking 90 minutes on AVX CPU Shorties are really short on GPU's which contributes to lower RTS while VLAR's only done on CPU's . This is mainly for newbies and Grant:-) |

Since none of the processed data has been reviewed and just shoved into a database, how about we start chopping that up into work units for the crunchers to start comparing? |

No Aps being split and replica DB offline = small panic |

replica DB is online again - replica seconds behind master 74,211 ...that is about 20 hours. |

Well it took about 8 hours replica to catch up. |

Anyone else notice slowed download speeds since the switch to the campus system? Maybe it's just the WOW event activity but it looks to be around 50% slower recently. "Sour Grapes make a bitter Whine." <(0)> |

I picked up a 132 WU download yesterday and they flew off the Transfers tab. SETI@home classic workunits 4,019 SETI@home classic CPU time 34,348 hours |

I haven't noticed anything, but most of my machines list their Average download rate from 1300 KB/sec to 1800 KB/sec. I would have to lookup how BOINC calculates that averages to see if I could reset it. Then see if the average is much less.

And the splitters continue to struggle... At least there have been bursts of AP work to help take the load off of MB. Grant Darwin NT |

Anyone else notice slowed download speeds since the switch to the campus system? Maybe it's just the WOW event activity but it looks to be around 50% slower recently. I was finally able to watch an AP download happen. It used to start off about 400 KB/sec and often end up well over 1000 KB/sec on the last update interval of the UI. Now it starts off about 200 KB/sec, but ends up about 900 KB/sec by the last update interval. Old HE link generally took 8-10 seconds for downloading one AP, and... the campus connection looks to take... 8-10 seconds as well. So I don't think there's much of a change on that regard, but since it is the campus connection, if the campus itself is going through a high-congestion time, then perhaps our traffic might slow down a little bit. If they're letting us use their connection without paying for it, I would completely agree with having a low-priority when it comes to QoS kind of stuff.

Did you check the boinc settings where you can limit the download speed? Maybe that got changed somehow? |

It has looked normal for the last several hours. Probably just a temporary traffic issue between me and the server. "Sour Grapes make a bitter Whine." <(0)> |

Did you check the boinc settings where you can limit the download speed? Both download and upload are set at a max of 1024 kilobytes/second in the web preferences, not doing overriding through local preferences.(*) But as shown throughout the year, with 300K max for APs and 120K max for MBs, I never get the speeds. global_prefs.xml <max_bytes_sec_down>1024000.0</max_bytes_sec_down> <max_bytes_sec_up>1024000.0</max_bytes_sec_up> global_prefs_override.xml <max_bytes_sec_up>0.000000</max_bytes_sec_up> <max_bytes_sec_down>0.000000</max_bytes_sec_down> (*) Now wondering though, when I have set a value in web preferences, but no value in local preferences, do the local preferences then still override the web preferences (set to zero = no limitation), or do they follow the web preferences and only override when there's a value > 1 set? Hmmmm, pondering. In any case, My true connection |
