At least according to the server page if I am reading it right, and I have two of them. One has been pending for weeks and I wonder if I will ever receive credit for it, not that it matters a whole lot. On the other hand, the pending user of the other one shows his CPU put in 188,755 seconds on it so if it just disappears – ouch! ;-). At least it will be interesting to see which way it falls.

I had one for a while, but my host finally sent it back a few days ago.

Now only 60 left out in the wild. Will the world as we know it, come to an end, when we reach zero AP 505's?

It's an exponential drop-off, so the fewer left the longer it will take.

I estimate the last one will come back sometime in mid December 2012...

And...the sky is falling.

57

Can we even hold out until mid-December 2012, at this rate?

Exponential decay is only valid when considering large numbers of events (e.g. uranium atoms decaying in a nuclear reactor). In this case, as the number of results in the field gets smaller, the fit to exponential decay will get less and less good. In addition, a host can only have a task for a limited time before it times out and someone else gets to process it. All AP5 tasks still in the field must have deadlines in May, so I doubt we will still be waiting for them to reach 0 in December.

I still have 7 Workunits with one result still awaiting validation (of 12,368 Results returned and awaiting validation)

We had a similar countdown at NumberFields@Home recently, and when we'd got down to 40 tasks, their Eric assured us that "all the remaining pesky WUs have been issued to 'reliable' hosts". Even so, I still got a resend several days later from a host which turned out not to be so reliable after all.....

I don't know whether 'our' Eric has used, or considered using, the facility for accelerating retries by using only reliable hosts: I rather suspect not. So, it could still be a while yet.

Timeouts don't count toward maximum errors, so theoretically a WU could keep getting sent and timing out over and over indefinitely. Not statistically likely, though.

I'm wondering what's going to happen with the stuck ones, like mine:

There's still maximum total results of 10.

That's what we are all wondering. I have 4 of those and there appear to be around 12,000 in total. The hope is that once AP5 in the field drops to zero, the good guys at Berkeley will reactivate the code that is supposed to validate WUs like that (returned after 2 other results validated but within the allocated time) to clear the system and we will all get our credit.

There actually IS such a feature in the Boinc server software? I thought I remembered it being floated as an idea, but did not know it really existed.

Yes, it's definitely there and available to be used. Accelerating retries

54 now. It takes time to get down just one task. Maybe by mid summer (northern hemisphere) we're at zero :-)

141 days? Must have been timed out and resent few times and now one of the earlier wingmen has returned it.
