Not sure what's happening, but inbound traffic is way up. DDoS attack? When everyone hits the per machine limit the inbound traffic ramps up, but outbound is still pegged & i expect it'll be another day till everyone hits the limits. Inbound traffic is still way above normal. My downloads are also taking several attempts before they finally complete (5kB/s at best, some as slow as 1kB/s). And i notice that the assimilators are no longer making headway- the queue is growning. Last time that happened was 2 (or 3?) weeks ago & they had to shut down the forums & some other services to get things working again. Grant Darwin NT |

DLs? Well I've received a lot more work this time than I got at this same time last week. Cheers. |

Eric will be looking into it when he can. Not until Monday, I trust. With the cricket graphs still pegged out at maximum, there's absolutely no point in him sacrificing a family weekend to speed up any other part of the system. |

Maybe I should have spoken a bit sooner as not long after my last post the dam burst. All 3 pc's are now happy campers with plenty of work. Cheers. |

Even my rig, which would not request work, seems to have a decent backlog of tasks to download. I feel much better now, as when there is available bandwith, I have wu's to download. It seemed to pick up speed as the day drew on. The less I looked at it, the better it did. Hmmmmm... Steve Warning, addicted to SETI crunching! Crunching as a member of GPU Users Group.

From the days earlier situation of not being able to request work, I have gone to plenty of wu's in the download cache with at least 80 AP units. I do the AP units in about 7 hours each, and with 5 cores crunching on them, bring em on! My chiller won't start cycling on and off tonight! Steve Warning, addicted to SETI crunching!

This is a classic computer science problem. N computers request data from a server at a poisson rate. If request succeeds, computer waits for big random some time. If request fails, computer tries again in 11 seconds + small random time. Expected outcome: Server overload. |

re allocated wus... one machine has ~1k wus one still downloading has ~720 wus with about 300 still coming in one with ~1600 wus the rest are just ghosts ... in terms of throughput, the above is just enough to cover the 3 day outage on 1/2 boxes only...the third will run dry by end of day 2 ... my caches normally run with ~6k-7k wus per machine to avoid seti outages/downtime but what i have noticed is that since the 3 day outage was implemented, the caches have been dwindling and pre last outage they ran dry and have not been able to refill over 2 successive cycles ... (i don't think its working very well) ... at the moment all the boxes are asking seti for more work about every 1-2 minutes and getting "reached a limit...." ... i know i'm not the only one that's in this position or feeling pain my pending credit is now at 857k+ ... it used to sit around 130k... |

DLs? We have currently: 40 WUs CPU/Core 320 WUs GPU But I'm confused - why? Jeff mentioned that this week we will have the high limit. But it's not. ----------------------------------------------------------- The one and only problem is the traffic bandwidth (max. ~ 95 Mbits/sec) between S@h and us. So why not solve this problem? What give it to buy new servers, if the memebers can't reach them? How is the currently status? We'll see one day the double speed or much more? If more and more people will upgrade their systems with GPUs.. one day noone can reach S@h.. OTOH, more and more people will leave S@h - because they can't reach S@h.. But always, the possible traffic bandwidth is too low! ![]() |

From my understanding, I believe that if the new servers work out as planned, the old ones can be turned into machines to do the science on the back end, without the need for a full 3 day shutdown. If that is the case, the bandwidth will not be an issue, as the project can run longer than 4 days a week. I know I read in one of the threads on here that it is at least being considered. ![]() |

DLs? Well I don't know where you are getting your figures from for this week but I have about 30% more work against this time last week. Cheers. |

I see the network traffic has dropped off quite a bit. It's still a bit high, but a lot better than what it was. However the assimilator queue still continues to grow- disk space may yet become an issue. Grant Darwin NT |

Hi, As I recall SETI lab has a limit of 100 mbit per second. |
Blake Bonkofsky ![]() Send message Joined: 29 Dec 99 Posts: 617 Credit: 46,383,149 RAC: 0 ![]() |
It's still pegging the outbound line, sitting right at 91-93MB. Uploads did drop off a bunch though, from about 35mb to 25mb. ![]() |

Yes it's only a 100Mb link and only the uploads have dropped off a bit but the downloads are certainly still running at max and likely will be for another 24hrs or so. Cheers. |

Hi, As I recall SETI lab has a limit of 100 mbit per second. Why can't that limit be raised on weekends When no one is around ![]() ![]() |
