We can all go to the Donation thread and donate to SETI/BOINC. Ms. Fuzzy Hollynoodles set up a thread and posted the link for all of us to put our money where are mouths are. I understand that some people won't be able to donate finacially, and that is fine. I personally felt so strongly about wanting to help that I did donate a little bit. I hope it helps. Jim |

Hey lighten up I'm not complaining just reporting my observation! Using boinc 5.00 before the outage the upload problem surface on my machines. I report this to Rom along with other projects problem not ready for for major version change and shortly there after version 5.00 was removed from the download page. From my testing in Alpha I think there may be a problem also with Boinc.exe. They had change to help the dialup users, so the chances are what? So if everyone would report what version of Boinc they are using maybe we could help the Dev to find the probem. I've only see a few that reported what version they were using. Don't jump on my chase without knowing all the facts. Maybe you could donate one of those hidden computers. Fred BOINC Alpha, BOINC Beta, LHC Alpha, Einstein Alpha

For the most part I agree! Prior to the major outage UL/DL was not an issue. My questions is what did they do, while the had the time to replace kernels or deamons... Something happened on the server that caused fewer threads/connection issues... thus dropped connections... It is a server issue, not clients, and serveal have noted pro/con about specific clients.. If Fred could donate a dual Opteron with the Sun OS it could solve a lot of problems... It could do half the work of all their servers.. Tony, Please consider a Donation to the Seti Project. |

Fred, Something in my mind told me I might not be right about Beta when I mentioned it working fine. I checked this machine and it has a (one) beta WU waiting to upload. I tried the update and it didn't go. Seti uploads at a faster rate than I crunch them. I have only three ready to upload on this puter which takes an hour to crunch and have probably done 7 or 8 today. |

Tony, I'm using 4.71 right now I have a LHC on my laptop waiting to upload for 2 days. I'm going to wait and see what happens. My 3.4 ht is slowly catching up [5 seti & 2 Beta] only because I force Eistien to download wu's so it's in earliest first. My 2.53 has 13 seti and 3 beta waiting to uplod and growing, some make it thru. I started having problems with uplaods when 5.0 was out. I've been running 4.71 on 3 of my computers here at home the other two are still on 4.70 which I will change on Monday. The connection is only as good as the weakes link, it could be when the severs get bog down boinc.exe elts go of the connecting. I only mention this for the dev to think about.

The server may only be half the problem, the unload problem also happens on other projects, so maybe part is boinc.exe. Fred, I've seen your emails to the Dev mail list. I'm using 4.71 and have experienced no trouble with any other project on any of my two puters. Even Seti/beta seems to be working for me. tony |

it still could be the servers. if they are maxed out / overloaded or bad chips / memory, etc, they could still drop connections. I wish I had the money to buy even just one machine to donate to them to help ease their load. Jim

btw a good Server must not be the fastests CPU, a good Server is working, 24/7 without Probs, and i think the SUN are one of the bests. and the little I/O to connect to the Web and all other Crunchers, that are not the Probs... July 15, 2005 The data server is continuing to drop connections, which is very unusual this long after an outage. We are working to figure out why. that is the Problem not the Servers Greetings from Germany NRW Ulli |

They are free ... so ... Still, obsolete is obsolete. The Sun D220R are so old there's no info on the sun website. |

Check out what these guys did with their Sun machines. Thanks .... StokeyBob ... for thanks for that informations __ :) WOW ! Recent average credit .... 19,789.92 |

Check out what these guys did with their Sun machines. user information Message copied from a different thread 6 years on Seti; 11 days ago ! We signed up so we could use the SETI program as a 'burn in' and reliability test for our grid. Current config: 128 x Sun Fire v20zs - Dual Opteron (mix of 248s and 250s) with a mix of 4GB and 8GB RAM and a Sun Fire v490 - Quad Dual-core UltraSPARC IV CPUs with 32Gb RAM used as a head node. We racked up 380,000 credits, and counting, in less 5 days (the grid has been assigned to other work since last Monday), but we'll try and get it back onto SETI whenever it doesn't interfere with 'real' work ... |

They are free ... so ... They will also tend to be more reliable. In a server system, I don't care what Microsoft says, their servers cannot equal Minis in performance or up time. And by the way, when you look at TCO they are not cheaper either ... pay me now or later ... I have always found the "Mainframe is dead" articles interesting because about the same number of businesses migrate off as migrate back each year. Run time expenses kill you in the use of large numbers of PCs to replace a mainframe ... But I digress ... |

I think you see the "Sun Microsystems" as a sponsor on the seti Classic front page because they donated the servers. I might be wrong though |

Hi! Berkeley use a number of SUNs as server. Maybe much cheaper PCs can outperform them? Once I did some tests comparing SUN "biiig box" with PC. Classic SETI, and some other integer only SW. For both, SUNs were very poor, not worth using them. Also, disks fail as often as cheap PC disk (with later being faster, bigger and cheaper). Even reliability is history. For example: there is only one SUN on top seti cruncher list, and per-CPU RAC is very low. Now, donated Sun is beter as cheap PC, but ... BR Iztok Position: I use few SUNs, when forced. Anyhow I prefer to migrate as much as possible to Linux boxes. This is a reason to hide computers, but my RAC tells something. |
