Re: What happened to validation?

Summa Sumarum, when i know to be away for more than 96 hours, during which period i always pull the net-connection, i will switch off the machine.....truely optimized from a WCG perspective. I think the BOINC crunchers are a more concious group who can live with it. Will adapt when this grace period is extended/shortened......

..... Someone brought 'The Terabyte Storage Argument' up....not impressed......got an internal 80gb and 2 external 300gb total 680gb, to put it in perspective.

Have a nice day nerd

Re: What happened to validation?

Yes, Sekerob, we will adapt. Tomorrow we will still be here crunching and debating the finer points of crunching. We'll be here until we get the job done and we'll be proud all of us.

rose Re: What happened to validation?

KnReed is following the discussion in silence and heard my thoughts over the hyperwaves.....1 week, outstanding.....now i can leave home monday morning presto pronto, come back friday night, switch on the router and flush about 16/20 WU's....this should cater for those that have machines that are of a previous generation alot more as well, not creating a feeling of dismissal AND make the Friday night great for 16/20 point collectors hugs

Re: What happened to validation?

1 week or 4 days, it makes little difference to me but I do realise 1 week syncs well with a lot of other peoples' work and travel schedules so yes, 1 week is good. The important thing, in my opinion, is that the change was properly announced this time.

Re: What happened to validation?

Sekerob, that sounds good, but is the reissue time being changed to 1 week as well?

If not, then what will happen is this:

Monday morning, you collect a week's worth of WUs to process.

Friday morning, since you haven't turned anything in yet, all of your WUs are written off and reissued to fast & reliable replacement hosts.

Friday night, you switch on your router and flush your results, but most of them have already been turned in by your replacements, making your copies irrelevant. Even those which haven't been turned in yet by your replacments surely will be soon, so the only effect of you turning in yours is to speed up the validations a bit.

The only results you turn in after Friday morning that do any real good for the project are those where the fast & reliable replacement host fails to finish their reissued copy. But since they are, after all, chosen for being fast & reliable and all, that will hardly ever happen.

In the end, the crunching you did that week did no real good. It doesn't matter to the project whether you turn on your router Friday night or not. I'm not trying to be cruel, that's just the way the system works. I don't think it's any kindness to encourage you to crunch all week for no real benefit. Better you should crunch on another project where your time won't have been wasted. Better still, of course, that you should leave your router on all week, but you apparently have good reasons not to.

In the end, the reissue time is the real deadline, whether the announced deadline agrees with it or not. Work turned in before the reissue time is good. Work turned in after the reissue time is irrelevant.

Sigh. Guess I'm not shutting up after all.

Re: What happened to validation?

I understand that the reissue time will be adjusted as you describe. The change will be gradual, though.

Re: What happened to validation?

I believe that the "deadline" has been moved to help with the problem pointed out above. I think it is set at 7 days along and the timer to send out the 4th work unit is slowly working out to that same time length.

This makes a lot of sense to me. In the meantime, some folks that have 5.4.9 of BOINC and some work units that have 3-week-deadline BOINC work units, may have some pre-empting going on. I have noticed it on the one machine I have updated to 5.4.9.

knreed (IBM-WCG) is working hard on getting this worked out. Thanks go to him. applause

In the meantime, Nothing is easy sad

Thanks for sticking in there and helping the science progress. Regards All. smile
