Message 29740 - Posted: 26 Aug 2009, 21:19:04 UTC

Two days offline for a weekend break, I switch on my laptop again and resume the task I was running. It completes after 5 hours of processing and reports, but alas 15 minutes after the deadline. Then I get the error message "result not needed" - because someone with a super-fast whizzy machine (which they, no doubt, don't own) has picked up the "late" task and done the whole thing in 6 minutes.

I am annoyed. Why should my work be wasted just because I am 15 minutes late? I could have told you I was about to finish... Can you not give longer deadlines and/or the ability to schedule in downtime on users' computers?

Why don't you read the other numerous complaints as well as the reply? Here is the just of it: The project needs the 3 day deadline to keep generating the new units as they are based on the completed data. And it is going to stay that way.



Are you using the optimized app?
Doesn't expecting the unexpected make the unexpected the expected?
If it makes sense, DON'T do it.

Thanks banditwolf. I infer from your reply that this project is not suitable for people who have relatively slow individual machines that are sometimes switched off. Perhaps it would help to state that clearly somewhere: I don't have the time or inclination to trawl through pages of forum posts hoping to find an answer to my question. I like this project as it's close to my own interests, but I don't want to waste my CPU time. I think I'll switch to something that is more flexible.

There are much slower computers running this project than yours and mine. You would be able to complete the tasks much faster by using the optimized app (I would say the sse2 version). Your system is similar to my own, just a slower processor. I can do the long tasks in ~100 min with a P4 @ 2.66. If you want help installing it myself or others would help. It seems hard but isn't.

apps -> http://zslip.com These are the approved opti apps.


Another thing you could do to only get one task is to raise the 'connect every' time in Boinc to over 3 days. You should then only get one task at a time.

Thanks again. The optmised apps certainly help things - I tried both sse4.2 and sse2. sse2 seems marginally better and turns work units round in about 75 min.

I'll stick with it for now...

Sounds about right for the time with xp. I go from 40-100 min depending on the task size which changes some. Good job getting it running.
