Post: Thanks Matt.I hope you have the universal fix it tool(a Louisville Slugger) around the office when Dan er things get messed up. I tend to use a hammer for my universal fix! @Jeff - If it's shutting down on it's own, the first thing to do is check the dust bunnies and clean them out. Lots of cases of reboot are because of overheating. Mine did it yesterday morning, and i haven't managed to clean it yet! Giz. |

A Sign The World Is Ending
(Message 1063333)
Posted 4 Jan 2011 by gizbar
Post: The real sign the world is ending is that IPV4 is about to run out... Hi Tom, IPV4 is the system that allocates IP addresses to computers and all that gubbins. In short, they designed the system so that it would provide about 4 billion IP addresses, a unique ID for every computer and internet enabled item on the internet. It's a 32-bit system. This doesn't include all the computers and stuff that have private IP addresses behind routers. We are rapidly approaching that limit. This is called the dotted quad... like 82.18.163.143 The replacement system is IPV6. They have been trying to get acceptance for if for years (around 1998 or so, I think), but the ISPs and others have been dragging their heels over it's implementation. It's not an unlimited system, but may as well be for it provides squillion's of numbers to use (technical term there, lol!). Honest answer, I'm not sure, and haven't got time to look it all up before going to work. It comes in the format - de80::ac97:3162:55b5:554f%12 - a little more complicated to understand, but provides a far larger number of addresses. The links will provide more information, and i may check them out myself later after work... Giz. |

GPU Users Group Server Donation
(Message 1062323)
Posted 1 Jan 2011 by gizbar
Post: But the ask was for other teams and individuals to earmark a small donation towards upgrading the ram. We just managed to purchase two full blown servers, and our group put the third one together from donations from just 13 people! It is all brand new kit, assembled and tested by Todd, who does this for a living, and currently has just boxed it for shipping to Berkeley! I won't divulge what was donated by the group without discussion with them, but I don't think the ram cost was anywhere as high as you are suggesting. I could be wrong, but I don't think so... The challenge was for others to extend what we have done, and make it at least as powerful as Oscar and Carolyn. I didn't think it was unreasonable to ask if people were willing to donate a little bit more. It's for their benefit too, in the security of hopefully keeping work flowing throughout the New Year and beyond. Although my name isn't on the server list of donations for Carolyn and Oscar, I made a donation earmarked for that, and put some in for the GPU Groups server donation. After raising what, $30k for 2 new servers, and our donation which will be there soon (because it got to the point where it was essential to have it done!) I was hoping many users could make small donations in the New Year to upgrade Synergy's ram. At the end of January, funds permitting, I will make another donation, either for the ram drive if that goes ahead, or for general use if it doesn't go ahead or has been completed. We have crunchers, but they aren't any good without any servers working to supply them with work. It's the same old argument. If 50,000 users put in $10 each, Seti could run for a whole year without worrying. The consensus of the majority seems to be 'My small donation won't make a difference, so I won't even bother.' But 'THANK YOU' to all that have donated. You are all stars, whether you display them or not! Giz. |

GPU Users Group Server Donation
(Message 1062069)
Posted 31 Dec 2010 by gizbar
Post: What would be amazing, and I throw the challenge out to individuals and the other teams, would be to donate enough cash to double the ram on 'Synergy'. Todd, if you would like to post the specs somewhere, I would like to see pledges to bring the ram up to the same amount as Oscar and Carolyn. Then we would have 3 servers of almost identical specifications, and able to balance the workload between them, with support from the older servers. 'Synergy' currently has 48Gig of ram. Can we get it doubled up? A Happy New Year to you all. Giz. |

Posted 31 Dec 2010 by gizbar
Post: It's not about anybody giving support I'm afraid. Your idea, while sound in principle, won't work in the manner you are proposing. Your idea seems to be to split an Astropulse unit between so many computers, in which the proposal would work. That would mean that the whole system software would have to be re-written to accomodate the new way of distributing work. But, as it stands, each computer would have to download at least one wu each, and as has been mentioned the stock app will take approx 200 hours on an Astropulse unit. If the computer is only using the screensaver and idle time, the work unit will time out and expire long before completion, thus there would be loads of electricity used and no results sent back to Seti. Even a normal multibeam wu may come close to it's expiry date, depending on how long the computer is on for. And, however you look at it, there would a be a massive increase in electricity costs, either to the school/college/university, or to the individual's household, if they are using the computer at home (if they are allowed) for doing homework. That is a cost that many families won't accept, if they know it's running, and institutions certainly won't accept the extra cost. I just can't see it working, I'm afraid. Giz. |

Help - cruncher does lots of work for no return
(Message 1061555)
Posted 30 Dec 2010 by gizbar
Post: Just for info, and not having checked the links provided at all, AMD CPU's seem to have a problem starting work units using the stock application. Not sure if it applies to both Windows and Linux, but I'm guessing it does. One way around it is to install the Lunatics optimised app, as that doesn't lock up like the stock app. Only problem is that I don't know if you can install Lunatics on Linux. Giz. |

"Temporarily failed download" on One Machine Only

Post: Have you rebooted the machine recently? If not, try that. Or, try opening a command window, then typing 'ipconfig /flushdns' without the quotes. Then start Boinc and allow it to ask for work again. If that doesn't work, clever people will be along soon... regards, Giz. |

Post: Does anybody have any idea, why Jocelyn can keep up with Carolyn? Carolyn is running the master database and Jocelyn running the replica. In the past, the server status screen always showed the replica quite a long way behind the master, but now Jocelyn seems to be able to keep up reasonably happily, despite being a much older machine, with far less ram and only 4 cores available to her. Is it because Carolyn can handle the workload much better so Jocelyn only needs to keep track, and not be backing up Carolyn? Your thoughts and ideas please. Giz. |

Post: I will be the Ultimate Age (to go with the Ultimate Answer) of 42 next birthday. I was born just before Neil Armstrong set foot on the moon for the first time. Did it influence me crunching Seti? You bet it did! Even though I was too young to remember it, I seem to have a strange fascination with such a momentous event just after I was born. Giz. |

BSOD with Seti, tried reinstall of everything...
(Message 1058832)
Posted 22 Dec 2010 by gizbar
Post: What power supply are you running with that? According to your post, you have 3 GTX470's in that rig? It may be stressing a rail too much, trying to run all 3. If it only BSOD's on running GPU units, I'd start looking there. Try running one card at a time and seeing if it BSOD's, then 2, then 3. If it runs 2 successfully, then try a different combination, but still 2. Then try all the 2 card combinations, then try 3 cards again. Even if I get a WU fail for some reason, it only gives me a computation error. It does not give me a BSOD. Yes, Seti is in a downtime at the moment. They are doing the regular backup and trying to re-stripe Oscar to a different size. It's taking a while, because all the data has to be copied to Carolyn, then Oscar has his stripes changed, then all the data has to be copied back again. NOT a trivial operation. Giz. |

Post: you are all lucky as far as internet speed goe's here in the uk we have the British telecom it siad i get upto 10 mb but it best is 1.8 m.b and its drops down to 500 bytes sometimes Agreed. I pay for a 10Mb service from Virgin and I get 9.5Mb on average. While not the cheapest out there, I like the reliability of the service. The only problem with it having all coming down the same cable, if it does go down I lose broadband, TV and phone. Some places now offer a 50Mb service and I also know in Bournemouth a company has installed a fibre network in the existing sewers, and offer a 100Mb service (Think it's called Cable City, but don't quote me on that).

The Periodic Briefcase (Element Collection)
(Message 1057483)
Posted 18 Dec 2010 by gizbar
Post: Hey Luke! Great to hear from you on here again! Sounds like an interesting, if expensive project. I only deal in 3 elements at the moment, and they are cryogenically frozen, specifically, Oxygen, Nitrogen and Argon. They are in liquid form, much more compressed in that state, but very, very cold! Must be easier to get them locally than me trying to ship anything from the UK! As you will know, some of them have to be kept under oil and suchlike to stop them reacting. And some of the rarer ones have only had a few unstable atoms of it, so they will be impossible to get. Good luck! Giz. |

Post: What software? Boinc? Did it download tasks? Stock, or optimised apps? At a rough guess, I would not allow it to run, then download coretemp or speedfan to monitor the temps, then allow it to fire up boinc. I would guess that it's immediately getting too hot. Is it a shop bought, or a home build? What else is running? Think your GFX driver is a bit old to run cuda tasks if you are trying that. More Info, info, info... Giz. |

I thought they both had the standard Boinc cache setting. I don't remember changing it, but could well have done in the run up to the server downtime. Thanks for your help. Giz. |
