Well, I've got my first 2 WU's finally completed for Seti, I had to suspend Rosetta though, because in the 24 hours I had all the projects running, Rosetta with a resource share of only 100 seemed to be running over 50% of the time, Seti ran for 3 hours during that period and the rest was Chess960...So last night I suspsended Rosetta in order to get Seti to run, it finally did, I just wish the BOINC client wouldn't have such an obsession with Rosetta...

Too bad you didn't leave it alone. Every time you suspend a project it builds debt, and when you un-suspend it, it'll be owed big time (and BOINC will develop an obsession....)

Trust in the force, Luke.


Oops, I didn't realize that...lol, trust in the force is hindered by my lack of patience...

Hi Stefan,
I can think of two reasons for your computer's behavior. One is if your Rosetta work units have a very early deadline and your comp is going into EDF mode to keep it from missing the deadline on the Rosetta units.

The other reason I can think of would be if SETI had run more in the recent past than Rosetta, such as if Rosetta were out of work, if Rosetta were suspended, or if SETI had demanded more processing because of it going into EDF mode.

The resource share is not a strict law, but is rather a general rune. If one project gets more of the share due to some reason, it will allow the other project to run more to balance the debt. The resource share will be correct "in the long run", but not always for the short term. BOINC however does a very good job of maintaining your chosen resource share over the long term.

Of course there may be a problem somewhere, but it doesn't seem likely.


The deadlines aren't for at least a week on all my Rosetta Wu's, even more than a week on a couple cases. I left it running Seti and Seti Beta in an effort to get through the Beta WU's I have left so I can detach from that project in order to give Seti some more working time...I know I haven't suspended Rosetta until last night, only in an effort to get Seti to start running. Like you said its a long term fix, so I just will have to be patient...And maybe rethink my resource shares...

Currently I have Seti at 300
Einstein at 200
Chess 960 at 100
Seti Beta at 100 (or maybe 200)

That's just off the top of my head, I'm away from the machine at the moment, at any rate, I'll watch and see...

Rosetta has 100 as resource share, and the rest?

The software that analyzes the workunits has been revised at least twice: In December 2000 when each unit took 5/3 as long to crunch (with a moderate variation depending on angle range) and with SetiEnhanced which takes a highly variable amount of time to crunch, depending on angle range (the angle in degrees the telescope drags through the stars during the 107-second duration of the workunit). If and when the new receiver at Arecibo starts giving us new workunits, I think that those units will be entirely different. The new receiver is called "Alfa" and it has seven different elements compared to the present receiver's one. With the two polarization angles with Alfa, I think we'll be getting 14 times as many workunits as we're receiving now.

What's the name of that little program that allows you to see the current work debt for all your projects? I had it, but I think I accidently deleted it...

Your looking for BoincDV


Yes that's it! :)

I have 12 active projects that run WU from 20 min to 80 hrs. The only concession I made was to give QMC (80 hr WU) 200 share, all others are at 100 share. LHC is set to 500 so I can give as much time as I can when they come on line.

The only time I've missed a deadline was when SZTAKI made a mistake on its estimate (10 hrs took 117.5 hrs) and they had to change the deadline on their servers to allow for the extra long WU to validate. That one report 18 hrs after its original deadline.

Boinc had one heck of a juggling act but got everything else reported on time. It was in panic mode for a week but it was a beautiful thing to watch.

Every project eventually gets its assigned share. I just leave Boinc do its thing and it all sorts itself out.

I crunch LHC and HashClash, which are both out of work right now. I crunch Einstein with a share of 1, and SETI (300) and SETI-Beta (50 at the moment).

If you let it go, BOINC will make sure Chess960 does not miss a deadline, but it will also stop downloading work when it gets well past its' share of work.

This is a long term strategy, and if you watch for a few hours or even days, you won't see it. Watch for weeks and you'll notice.

Assign your shares as you wish (based on how you want to divvy up the time) and then let 'er rip. It'll be fine, promise.


I'll have to try that, and maybe get some more machines to deal with the load of projects.

Has anything drastic changed to the WU's since June? Are they those 15 hour mammoth WU's still? It doesn't matter to me, I just have to plan around my other projects. And most likely drop Seti Beta, I can only handle so many extremely long WU's at once! :)

I crunch several projects with short and long work units, and aside from looking in on BOINC occasionally, I leave it alone.

BOINC does a pretty good job of making deadlines (suspending shares temporarily) and sticking to resource shares (by suspending projects that get too far ahead).


I've got to work out my resource shares, especially with LHC's and Chess960's...

LHC half the time doesn't have work, and Chess seems to always be running WU's on BOINC's overscheduled CPU deadline mode...

I've had to set no new work several times because I was getting no other work done...Maybe if I do a 50 workshare...

Thanks for the welcome!

I did download that optimized version by Simon and it seems to be working :) After 45 minutes its at 10.8%, which, unless I've made a stupid mistake, would mean that the WU should be done in 7-8 hours...a huge improvement from the ones before, without optimization. Those were averaging between 14-17 :O Great job Simon!

Welcome back.

As far as I know, the work unit size have not changed since 1999. Over the years the amount of data that can be mined out of a WU has increased but the ever increasing speed of computers easily kept up and even reduced crunched times considerably.

The latest Seti client searches even more deeply into the WU which is why it takes longer to crunch. The client does use program optimization techniques to mitigate the extra long crunch times that resulted from this analysis, but it still takes much longer than we had become use to.

The better written software is one reason the huge increases in speed optimization produced in the past on the old client can't happen. Still, the CPU specific optimization does provide 20 to 30% increase in speed over the standard enhanced client.

Welcome back!

Yes, we are still running SETI@Home Enhanced, and thus each workunit takes much longer to complete.

Happy crunching!
