Message 634938 - Posted: 6 Sep 2007, 22:13:25 UTC

Guess what? A *second* drive on thumper failed this morning, around the same time the other drive failed yesterday. This system is on service, so we should get some replacements soon. But there's no obvious signs of why these two failed so close in succession. They were both on the same drive controller, but there's a 15% chance of that happening at random. The temperatures all look sane.

In better news, we got to the bottom of the weird splitter sequence number problems I spotted yesterday. Now that we understand what happened and why this really isn't a problem at all. Basically, data that was meant to be tacked on the tail of one raw data file ended up at the start of the next file instead. No biggie.

As far as those overflow workunits taking forever... Jeff and Eric wrote some code (and checked it twice) to scour the database for such workunits and "cancel" them. Immediately we saw our pipelines flood with requests for new work.. so expect some delays for a while. We hope to eventually give credit to those who got stuck with these troubled workunits.

Excellent news - thanks for getting rid of the "Splitsville Evercrunch Specials" - it'll save us a lot of explanation time in Number Crunching.

And to be offered credit as well - more than we ever asked for.

I've linked the news into NC here.

I said I was going to keep bitching as long as BOINC was not doing anything!! Over the last 9 days BOINC has been able to long on the SITE server once to get work, my systems are Intel duan 3.6GIG systems with 2GIG of RAM so it takes them about 12 hours to crunch a downloads worth of work.. They have not been able to log back on the server and get any more work! What follows is the message:

Thanks Matt for an update... Anyway - from the brief analysis - SETI@Home has a approx. 1 week MTBF time....

My 6 computers have received nothing since 0012Z and they've been pinging their little heads off. Looks like things went kaput about two hours after Matt's original post on this thread.

Very irreverend of you... I guess you're not of The True Faith?

9/7/2007 8:46:59 AM||Suspending computation - user is active

Why you got that enabled? There should be no need. Boinc shouldn't interfere with normal operation in any case.

New work is trickling in fine for this system. Just leave it to try a few times and all should settle in ok. Also, it's a good idea to join a second Boinc project so that your machine isn't idle if one of the projects has any hiccups.

Are we just wasting are time leaving our systems running??

That's up to you to decide...


Happy crunchin',
Martin

http://setiathome.berkeley.edu/sah_status.html says splitters are down and there's no work to be had.

I've had no problems getting work until today. So now I'll just have to crunch my 8 day's worth of cache and then go on to other projects.

The beta site still has work http://setiweb.ssl.berkeley.edu/beta/status.php

No work either. I think when the project has no work, the server should reply with "wait 4 hours and try again". I don't want BOINC checking every 1 min 0 sec for work just loading the scheduler for no reason.

Right this is really getting to me. That people are screaming and shouting about not having any work for crunch with out actually looking around the forums to find out why they are not getting no work.

1. If you all had set your work creche to 10 day then you would be still crunching right now because i am i have plenty of work units why because i think about the number of outrages seti has so i planned.

2. If any of you had been bothered to look at the server stats page once in a while you would find the every splitter is disable so they would not be making any work for you.

3. If you had read matt's post properly then you would of found out why there was a problem with sending work...:-

Really some of you have to WAKE UP and start thinking for yourself instead of bothing the seti team with stupid I CANT GET ANY WORK AT THE MOMENT posts. They are try there best to fix the problem but they don't work on seti 24/7 like some of the other projects the do have other things to do.
So why don't you give them a break.

Your doing a great job matt keep up the good work

Reverend. With such a title, you should know something about respect. Would you kindly respect the fact the this is the tech news forum and post your comments/complaints/questions to the Number Crunching forum?

And the kitties say..........'Thank You, kind Sir'.

Your work cache (a creche is a baby-bed) depends on your Connect Interval along with the 'Maintain enough work for an additional x days' settings.

Go to Your Account, select General Preferences and update your Network Preferences. There are 3 (4 if you count Default) venues you can customize for your use. They are called Home, Work, and School...but you can use them for whatever you feel like.
