Hello !

Watching the calculation of a WU I wonder why at the first 4 minutes my BOINC client says, that "time to completion" is about 5 minutes, but reaching a progress of ca. 55 %, the completion-time continuesly rises (up to 3.5 hours, which is my average WU calculation time) and the progress slow down very much ?
So what's the reason for this confusing behavior ?
Regards

The algorithm for estimating the time to completion just doesn't work well for SETI units. Ignore the estimate and the progress indicator, it's not linear.

Would have thought they would have fix this by now :(. O well!

Jaaku,

This is a cosmetic issue. More important things to fix and test.

We are only into M1 to M2, though my perusal of the database show lots of M1 tasks not done yet.

Where do we see all the milestone criteria anyways? i've been searching for it to no avail..

It's been a while since anyone has mentioned this problem. Maybe a good solution would just to make the time calculation logarithmic instead. Sort of "fudge" it. Still wouldn't be perfect, but would probably be closer. Especially if you tweaked the equation a little.

Maybe something like ((1-n)*original estimate + current CPU time) * (1-n) where n is the fraction done (0 to 1) or (% done / 100). This would tend to stabilize the calculation somewhat in the earlier stages, and it would converge on the same result in the end.

Off of the "Your Account" page there is a spot for Pending results. This is where you would see the list of work accomplished and what you have pending.

Tracking down the links you would be able to go and look at the actual results below.

The issue here is that SETI@Home has such a wide audience that the amount of data sloshing aroud is HUGE. So, the core table has high activitiy.

With this high activity came problems. So, the pages were turned off to allow the system to "run" without performance issues. We all hope this will end soon.

I do have a description page for pending results that you may be able to get the flavor of it if you are real curious.
