Message 3094 - Posted: 13 Nov 2005, 15:21:12 UTC

After spending over 3 hrs digging into the help files of the BOINC manager and finding nothing that accurately describes what's happening, let me start from the beginning.

Several days ago I installed the BOINC manager on 4 machines (3 Athlon T-bird cores)running at approx 1.2, and 1 Athlon 64 3400. On one of the t-birds I attached to the Einstein project, the other 3 I attached to the Einstein project as well as the Rosetta project.

Everything was running smoothly until my 2nd Einstein job had a completion time of over 80 hrs. and I received a computational error upon it's completion. In a attempt to rid myself of this job, one thing lead to another and I eventually uninstalled and reinstalled BOINC on that one machine. I read somewhere in the help files that account information can be "transferred" from one machine to another when connected. It appears something to that effect occurred here. The first thing I noticed was that the Rosetta jobs upon starting would very quickly run up to 10 to 30% completed and then seemed to stop. The %completed would remain unchanged and the time to completion would actually increase with time. I suppose it would be possible that the job ran up to 30% in 2 or 3 minutes because there was very little "work" in that part of the job and BOINC was attempting to "correct" the completion when the job reach a point where in ran more slowly.

Anyway I've been unistalling and reinstalling until I'm about to drop. As of right now I only have Einstein installed on all 4 machines and 2 of the 1.2 Athlons are running at a pace that seems to be about 3 times that of the Athlon 64.

If it's "normal" for some jobs to run very quickly through the first part of a job, I may no have a problem, but none of this began to occur until I had that 80 hr Einstien job and eventually uninstalled and reinstalled the BOINC manager. Done.

I think this is absolutely normal. I had jobs that completed within a few minutes and jobs that took 1,5h to go to 30% completion. In fact it seems in the last week the average time of a workunit was increased dramatically.
Hab jobs <10 min. Now have several with >120min.

So perhaps this was just a coincidence

And you are absolutely correct. If I could delete the above post I would. I won't go into the embarrassing details, but it appears to have been a case not seeing the forest because there weren't any trees to be seen. Time will tell.

Thanks for the help,
