... you might want to read the Checkpoint Save FAQ explaining how to log the progress in the message window of BOINC manager. [out of topic] But you wil read (and update) it, Sek. Some links in your FAQ thread 11332 are dead or moved. a. sample image of AC@H not exists (there). b. link of Core Client Configuration moved to ...edu/wiki/Client_configuration. Cheers |

Thanks CP, duly fixed.

I would like to thank everybody for the responses.
My computer is a little old (laughs..), I bought in 2004, is a Pentium 4, 2,4 GHz. I'll keep, for while, only the Rice and DDDT projects, but I intent to change my computer in few months and, so, I'll run the other projects too. I think the WCG is a great idea and I knew about it, in a interview on a brazilian cable tv, with Jean Paul Jacob, a brazilian phd responsible for the research center of IBM in California. I'm living in Rio de Janeiro. If you need some help or information about Brazil, I'll be glad to help you. Thanks Mauro mauropessoa@hotmail.com |

Mauro, if you feel a little out of the picture with your P4 2.4 GHz you might be interested by a few facts that I have posted at the end of this thread Long WUs still occurring last week. You should feel better after that.  Cheers. Jean. |

Thanks Jean
I read the posts about the old computers and I agree with you. I think that a lot of people have them because they don't need to use the total computing capacity. I use only for internet, and few works in excel or word, when I work at home. I'm using the computer only 4 to 8 hours/day and, for while, I'll run the Rice and Dengue projects, before buyng another one, and use it at least 12 hours/day. But I think that we can do a important contribution to WCG and if I start asking the capacity of CPU's, will be difficult to bring new members to WCG. It's good to see a lot of members discussing about, because show the commitment with a good cause. Cheers, Mauro. |

Well, I have a Pentium 4, and I'll have you know that it keeps the room nice and toasty by crunching WCG projects during the winter. I'm running at 100%, but I need to crank it down during the summer.

Same here. Its 0°C here at the moment. May as well crunch and heat the place at the same time with the old P4.

Sorry to say that I've switched from FAAH over to another project.
For some reason, the agent bombs out and I lose all the computing time, as the WU starts over again. So after running 2 days for maybe 20 or so hours of CPU time, the crash caused the time to start again, effectively having the 2 days of machine on-time be for naught. Also, that screensaver graphic gives my machine fits (I turned it off, but when I downloaded the latest BOINC version, it reset my screensaver to the FAAH, and after I came home from some errands, I realized my machine had rebooted.) I've been off FAAH for a bit now, and my machine hasn't had any trouble at all. I'll come back when I think some of the problems with FAAH is resolved. |

hi,
----------------------------------------The screensaver is an explicit option in the 6.2.25 release, so if you did not tick that box, the installer should not have re-activated the ss. 2 days and 20 hours implies a machine with either little power or ram. FAAH does require the occasional few hundred mb. Have you allowed enough space for the swap file? We recommend 2gb, it's not reserved, but allows the task to occasionally take 400mb when need be. And, the more ram you allow BOINC to use (when the system is idle), the faster the job will run as it reduces disk i/o. Suggest, to change the profile and try e.g. only RICE or HCC projects. They require little ram and checkpoint more often so if something crashes they can restarts much nearer to the point they were interrupted. ttyl

I think I've given it enough disk space of 4GB. I have 1.24GB of RAM.
In 1 1/2 years of running, I've only had problems in the past 2 months or so, and not just with the screensaver, and always with FAAH. I usually don't use the BOINC screensaver, because I've watched the agent stop when it tries to start the screensaver. I was using one of the default Windows screensavers, and when I downloaded the newest version of BOINC last weekend, I walked out of the room, and when I came back about 1/2 hour later, the screen was off, and when I moved the mouse, the BOINC screensaver flashed briefly, and I saw the agent wasn't running anymore. I restarted the agent, then went to changed my screensaver to the one I was using before. Strange. Before that, I had the machine running, and noticed the agent wasn't active. When I opened it, it reset the time back to 0 and started the WU all over again. It's done that twice, with one of them losing the aforementioned 20 or so hours of CPU runtime that had taken my machine over 2 days to run. The CPU runtime is low because I wasn't running the machine all the time, there are days when I'm not home and it's off for 14 hours. I'm running the Rice project, and so far, no problems at all. No reboots, no lost CPU time, no mysterious stopping of the agent. Again, this seems to coincide with the longer FAAH WUs. The screensaver issue isn't the main problem, it's the agent stopping and losing my accumulated work. It's a waste of time to have a machine run for several days, only to have BOINC doze off and then start all over again. This forum has become busy with all kinds of problems with FAAH and longer WUs. To me, the correlation between the two is suspicious. I'll run the Rice project and see if I have the same bad luck as with FAAH. |
