I crunched this APU for 6.5 days, completed successfully, but got 0 credit. What's up with that?

Your wingman had too many repeating pulses. I crunched an AP WU from August 19 to September 3 and I am still waiting for my wingman to finish. Fingers crossed.

I don't know what repeating pulses means, but it shouldn't have anything to do with my credit since my pulse seems to be fine. Thanks for the response though.

Your wingman errored out of the Astropulse unit. Don't worry though - it has been sent to a third cruncher. Once that's done, it will update your credits.

WHY

What causes an AP WU to stop at 98% in order to have a regular SETI WU run at high priority? The SETI unit has an earlier date but it is still a week away and it only takes 2-3 hours to crunch.

Wouldn't it be grand if WE could control that?

And with the comments below about wingmen and receiving 0 for an AP WU, what happens if while I'm sitting at 98% and causing someone to wait? Can one of us (OR BOTH) end up with 0? On the same note, is there a way to tell if someone is a wingman or (to keep the analogy going) a squad leader?

I checked your tasks and that Astropulse Wu hasn't been finished and reported
yet, and is already overdue, and it has been issued to a third computer on the
9th Sept, and since that computer (a 3.2Gig P4) was doing AP Wu's in about
499,000 seconds, (5.7 days) you need to finish and report your task today,
otherwise you won't get any credit for it.
If you think your computer is never going to finish an AP task within it's
deadline, go into your account and change your Seti@home preferences to not
do Astropulse,

My computer (Polywell, Athlon XP 2700) has been doing SETI@Home for about 4 years, 24/7. Performance has been up and down, sometimes drastically for some unknown reason. The other day, I noticed it was taking an inordinatley long time to finish a WU, then I saw it: Astropulse. I did not get any notice about Astropulse and did not know what it was. It has taken 57:45 hours of CPU time, is now 35% done, with completion due in 78:29 hours. Is this gonna work?

Go to the SETI home page and read the Planetary Society article on Astropulse. My first AP WU took 115 hours on my AMD Opteron 1210 at 1.8 GHz running Linux and I am still waiting for my wingman to finish. He probably won't meet the deadline and the WU will be resent. Meanwhile I am crunching another AP WU, together with 5 other projects. Cheers.

Along the thread of performance and utilization...

1) I understand there are "venues" but what I would prefer is the ability to let BOINC run at 100% when I am not using the computer but continue to run even when I am using it at say 80% utilization. I have a dual processor machine and when I set it to run all the time it takes too long to do things I want but I dont want BOINC to stop just cause I moved the mouse or started a browser.

2) Additionally, how do I set priority? I want LHC to have priority always, and only do Seti when there no LHC to do.

3) Whats the fastest BOINC processing computer for use at home? Something not too expensive and you could get off ebay?

PS: I used to do a lot of crunching back in 2003, I was up in the 98th percention for processed units. Had problems with the switch over to BOINC and stopped processing for a long time. Now with the launch of LHC, very interested in getting back in.

Thanks.

Since all workunits have to be verified, the other person who has the same workunit as yourself is your "wingman" for that workunit.

O.k., I checked out the Astropulse principles and objectives as suggested. But I don't understand about the "wingman" concept

Each work unit is sent to multiple computers, and then the results are compared. If they agree, then credit is given. If they don't agree, then the work unit is sent out to a third computer for a 'tie-breaker' situation.

The other computers assigned to the same work units you do are your 'wingmen.'

Edit: Scooped once again. Oh well...

As of Thursday, 18 Sept 08, CPU time is 91:44, progress is 53.374%, time to completion is 60:14. The deadline is 10/13/08. I guess it will make that deadline, but jeez.

Maybe I need a faster computer, a bigger hard drive or more memory. Probably should use it less for other stuff if I ever want to get this thing over with.

why is it that the cerdit for the autopulseare not showing up on the boinc manager after the work has been completed and receiving 700+ credits for it it had done this like 3 times already.i know that the other mirowed one has also been completed as well but still have not gotten the credit to show up.im running a AMD3.0 duel core over clocked to 3.14 running xp doing the autopulse in a about 3 days

You must have gotten credit for them a few days ago. I didn't see any Astropulse units in your task list (though I didn't click on all 27 tasks). Once you get credit for work units, they disappear from the list after a day or two.

Because Astropulse is a part of SETI. It would be rolled into your overall stats.

Like others, my hyper-threaded P4 is taking longer that the projected time to finish an Astroplulse unit. Currently its at 38:45 CPU time and 29.762% done. The original projected time to complete was about 72 hours - so it will take a lot longer to complete the Astropulse unit than originally projected - that's not a big deal - just a longer deal. A normal Seti unit takes about 4:30 hours for me to finish. I run ClimatePredictor@home and Einstein@home and Seti@home. But, I've noticed what appears to be a bottleneck with the Astropulse unit. If I run both CPUs (i.e. ClimatePredictor or Einstein) and Seti Astropulse the Astropulse runs slowly. Keep in mind Climatepredictor (or Einstein) run on one of the CPUs and Astroplulse runs on the other CPU. The bottleneck is when they both run at the same time. A normal Seti work unit exibits no bottleneck. Using Task Manager I can see each @home unit runs at about 100% in its respective CPU - but if I run only Astropulse and no ClimatePredictor (or Einstein) then the countdown to completion on the BOINC Manager decreases at about a second per second. If I run both ClimatePredictor (or Einstein) and Astropulse the countdown for Astropulse slows to about one second per 3 seconds - which is why its taking alot longer than the projected completion time to finish the Astropulse unit. The ClimatePredictor (or Einstein) (or a normal Seti unit) countdown rate (times) are unaffected whether one or both CPUs are runing. So.......Astropulse does not appear to play well with other @homes. I suspect the bottleneck is competition for a math co-processor or numeric data processor or something like that. I don't know how to look into my system to see if that's the problem - but the reason for this Post is to suggest that someone look into the idea to see if that's the bottleneck and suggest a way to solve the problem. Maybe if the length of each calculation in Astropulse was shortened it would make things go smoother (??). :)

I've never had an accurate completion time. Multibeam units finish faster than the estimated time, and Astropulse units run longer. It's because BOINC uses the same duration correction factor (DCF) for both types of work units.

Also, both of my machines occasionally have periods where the 'to completion' time seems to pause for a few seconds on both Astropulse and Multibeam units. I would assume it happens to all computers.

**************************************************************************

The DCF is interesting - but it doesn't address why Astropulse slows down so much when both CPUs run. The slowing down doesn't happen with the normal Seti units and the slowing down doesn't happen when Astropulse is the only @home running.
