You've just hit one of the snags of using a proxy, they have a habit of stopping working if you hit them too hard too often with one target address. Bob Smith Member of Seti PIPPS (Pluto is a Planet Protest Society) Somewhere in the (un)known Universe? |

What has happened ???!!! This morning I look at my tasks and Seti tells me I aborted all 200 tasks last night at 18.47 UTC although they are still running, uploading and reporting. No credit for any tasks since then and they don't show as pending or validated even after I reported them. Anyone else got this problem yet ? |

Nor here, earlier I had a Win7 BSOD, totally weird, that was a driver problem... The T1 Trust, PRR T1 Class 4-4-4-4 #5550, 1 of America's First HST's |

What has happened ???!!! Yes, this is normal seti@home function now. Auto abandoning all tasks at random. Apparently, I got full cache of 22 astropulses abandoned yesterday (again!). This is the third time this happened to me. Usually it happens when scheduler connection times out a lot. Fun. You should manually abort all those tasks now. |

Add to that, neither the MB or AP assimilators appear to be working. They both show green on the server status page, but the number waiting to be assimilated continues to climb for both. Grant Darwin NT |

What has happened ???!!! And to add to that, since the last outage i've had a whole bunch of tasks timeout- within minutes of getting them (one took a couple of hours but most were within 10 minutes). Grant Darwin NT |

Since the grass needs to be cut, everything seems to be running optimally. I know the really heavy consumers of internet traffic are busy elsewhere, but limiting internet downloads seems to help the schedular and the download speeds. Now if we can switch over to AP's with no Shorties or MB's that would be an excellent test of increasing the bandwidth from 100 Mbts to 200 Mbts. Posing a question - Can 100Mbits handle confortably just AP's with no MB's as 100 Mbits seem to be able to handle just MB's currently???? Its a question that begs IMHO to be answered. Thanks Bill aka Tom |

Since the grass needs to be cut, everything seems to be running optimally. AP tasks are about 20 times more data to transfer, but only require 10 times the amount of time to process. At leas for CPU. I imagine GPU processing would make the ratio even worse. However if that was the only work going out it would be hard to say. Not all the current machines running can complete an AP tasks in time & some choose not to do them at all.

Posing a question - Can 100Mbits handle confortably just AP's with no MB's Well, as I see it, an AP WU is 8 MB; our download bandwidth peaks at 94 Mb/s, being generous that's 10 MB/s -- so we max out at 1.25 AP WUs/sec! Any more pressure than that and we get into the realm of lost ACKs and ghost workunits. |

It´s simple question of numbers... If with MB only, the graphs shows about 75% average usage of the avaiable bandwith and AP uses aproximately the same band... need to say anything else? What they realy needs is split the work in two diferent lines (100 MBps each) or... finaly put the 1GBps link to work... The actual configuration with MB/AP running at the same time reaches it´s full capacity a long time ago. In bussines (ok SETI is not bussines but the rule apply in the same manner), every IT men knows, you could never use an average off more than 3/4 of your total bandwidth or... your will start to loose clients. Besides mantain your clients you need to have the capacity to allow new ones. Any other solution, if works, will work for a few amount of time, too many new powerfull GPU´s are expected to come to crunch in the next months/years... |

The SSP comes up ok here nut have been having reporting tasks since last nite but got thro eventuly and got some more tasks ( mostly ghosts) . Hope there is'nt a problem developing but if there is we'l get thro like always Life is what you make of it :-) When i'm good i'm very good , but when i'm bad i'm shi#eloads better ;-) In't I " buttercups " p.m.s.l at authoritie !!;-) |

has anyone else noticed that their Valid tasks are increasing ?? |

and the problem with that is? That it appears that the db_purge.x86_64 daemon has joined its comrades in the sah_assimilator union - and gone on strike. |
