Location School, Preferences Home?
(Message 9369)
Posted 15 Feb 2005 by Friedrich S. Post: Hello, I can't convince my computer that it is located at "School". It insists on using the preferences for "Home". I went to my account under CPDN, then to My Computers, then to that specific computer and it says that location is "School". But whenever I update the project, the BOINC client says "General prefs: using separate prefs for home". Which of course are the wrong preferences for this specific machine... Any ideas? Thanks!

Merging 2 Cross Project IDs?
(Message 9368)
Posted 15 Feb 2005 by Friedrich S. Post: > Friederich: Did you het this solved? > I have exactly the same issue. How long > would it take for synch to take place? Resourcewise CPCN is on 100, SETI on > 10, EINSTEIN on 15. I think the preferences are the same, which probably means that the accounts are linked now. I believe that was not the case yesterday, so it took 2 days, maybe because two of the computers are not running continously. I just changed one setting, so I will see if that propagates in the next days... Friedrich |

One note: capitalization matters, all email > addresses should be in lowercase. Thanks for your answer. Currently I have no two BOINC projects on the same computer. I have two running CPDN and one running Seti. Based on what you are saying I understand that the two CPID will never synchronize because of this separation? Friedrich |

Merging 2 Cross Project IDs?
(Message 9190)
Posted 12 Feb 2005 by Friedrich S. Post: Hello, I am not sure how I did it, but I ended up with two Cross Project IDs (CPI). One under Seti and one under BOINC. Should they not be the same? Both have the same e-mail address, but the preferences do not seem to propagate from Seti to CPDN or Vice versa, so I assume that they are not linked... How do I migrate my Seti from one to the other CPI? Is that possible or do I have to detach and then attach with the other CPI? Thanks! Friedrich |

Every model will leave 330 MB on my hard drive? The FAQ does not mention that AFAIK. Is that information needed later of can I safely discard it? (I have enough space for my two CPDN WUs but not enough to keep all the results.) Friedrich |

But is that not a big difference? A model that failed because of a hardware glitch or a file error could have been important & valid whereas a negative pressure certainly shows the model is flawed. Do they check that and run models again if they failed because of hardware glitches etc.? > There are several threads about success rates on the phpBB, (which is down), > and one of the admins said the ratio > is about 1 in 7 successful, so don't get too discouraged. Well, I hope the scietists and their programmers now what they are doing. If they consider that acceptable, I can live with it. I am just surprised that it happens relatively often. And I am wondering if there are not strategies to compensate for the hardware-related failures. Friedrich |

Posted 10 Feb 2005 by Friedrich S. Post: Hello, I now can join the "Team of -5", too. On my Pentium 4, 2.8 GHz HT with BOINC 4.13 & CPDN I just lost a model just after the 6th trickle. Isn't there a way to deal with it by the way the files are written in CPDN? A strategy like: 1) Write data to temp file. 2) Verify 3) Rename if verify successful, otherwise go back to 1). 4) Build model slowly in incremental files (e.g. every trickle). And on load: 1) Load file. 2) Verify. 3) Reload if unsuccsessful 4) If still unsuccsessful, load earlier time steps (of incremental files mentioned above) until you reach a stable point and restart from there. That way you would loose a trickle rather than the whole model. and it would be easier to recover, e.g. by playing back a earlier backup. Friedrich |

Windows :
Seti@home and BOINC conflict
(Message 8743)
Posted 6 Feb 2005 by Friedrich S. Post: I have Seti@home classic (command line version) and BOINC CPDN running on the same machine. After booting, Seti@Home uses up all CPU-time, just like on your machine. I found out that when I exit Seti@Home and restart it, it now only uses half of the CPU-time with the other half going to BOINC. My guess is that it might be an issue with which software starts first. Maybe that works for you, too. (But I am in the process of switching completely to BOINC anyway. I just need to empty that queue for Seti Classic.) Friedrich |

Upgrade BOINC 4.13->4.19: Strange effects on progress?
(Message 8710)
Posted 6 Feb 2005 by Friedrich S. Post: Hello, I had some strange effect when unstalling BOINC 4.19: <b>Machine A: BOINC 4.13 & CPDN</b> After upgrading via Suspend, then Exit and then installation of new BOINC version without prior deinstallation, the value under "Progress" jumped from 2.18 to 3.6% (or similar, don't remember exact values). Work then seemed to progress much faster, too. Since that seemed strange to me, I exited BOINC (without suspending) and restartet it. Progress was back to the original value of 2.18 and original speed. <b>Machine B: BOINC 4.19 & Seti</b> New installation of BOINC on new machine. After some trouble of connecting to server finally it downloaded WU for Seti. I had not done Seti under BOINC so far, but once the calculation started, work progressed so fast, that even without prior experience I could tell something was wrong. I estimate that the SETI-WU would have taken about 15-30 minutes to complete on my Athlon 1200. Impossible! I exit BOINC and restarted. Progress from there on was much slower, about 1/100% every 2 seconds or ca. 5.5 hours/WU, which seems about right. Did anybody see similar effects when upgrading to or installing 4.19? Friedrich |

HT & CPDN - Let me see if I understand it...
(Message 7657)
Posted 26 Jan 2005 by Friedrich S. Post: Hello, I have a P4 with 2,8 GHz and HT. I am running CPDN on one CPU and the Seti Classic on the other (emptying the queue). I am considering to run CPDN only and use HT for that. After reading through the FAQ, Forum and other sites, I am still a little puzzeled, so let me see if I got it right: 1) I can run CPDN under BOINC 4.13 on a computer with HT. And (usually) it does not crash. (There were some earlier messages somewhere where it did.) 2) If I do that, my computer works on 2 WU instead of one, so I need twice as much disk space (2x 700 MB), too. If the above is right, I have more questions: a) If I run CPDN only, will HT actually accelerate the calculation? b) If I run CPDN only, will the WUs still be swapped every 60 minutes (or whatever time intervall I set under preferences)? What/How will they be swapped, e.g. switch processors? c) Is there a way to temporarily (e.g. 30 minutes) to suspend calculation for just one of the two? Thanks lot for your help! Friedrich |
