Hi all, not sure if this ought to go here but since the topic reads SETI website... Anybody else having this /problem/ or is just me? There don't seem to be more units. Started a few days ago when my Debian box didn't get anymore: Project has no tasks available. What gives? Any ideas? Regards, Peter Heinrich Claus.

We're all in the same boat. Whatever is wrong, it's been like this all weekend, wasn't fixed today apparently, perhaps during tomorrow's maintenance cycle the problem can be addressed.

Seems to have been fixed. At least one machine is fetching new wu's again.

Yeah, there are some AP units getting out, as well as the occasional resend.

Um, any idea what kind of units are /these/? Average processing was between 6 and 8 hours per unit. Lately I seem to be getting monster packs with processing times soaring up to well over 100 hours each. Anyone seeing the same? Didn't touch the settings.

You're probably referring to Astropulse WU's, which, depending on your CPU, can run 10-20 hours each. The estimates of 100 hours are somewhat exaggerated, until you've completed 10 units and they've been validated. Then, BOINC "learns" how long your system takes, and adjusts completion times accordingly.

EDIT: given your relatively slow processors, my guess is it might take 36-48 hours to complete an AP.

?? Looking at my stats, it ought to be clear I've done just a few more then 10 units over the years. However, the issue seems to exist on windoze only. Debian never reported such timings. On the contrary, Debian still doesn't get new units. The image link to a screenshot I've just taken verifies my numbers. One of the last units - aprox. a week ago, and both of those received this evening are indicating times 100+ hours. I'm fairly sure it's the units, not my system, nor any fancy new algorithm.

If you'll take a look here, you'll see that only 5 AP units have been completed and validated for your Windows rig, so BOINC hasn't enough data to properly calculate an average time to completion for this class of WU. Your screenshot, presuming a direct correlation between time and amount completed, would indicate that the first WU would finish in about 72 hours, the second in about 87. Certinly not a huge disparity from the estimate, but a disparity nonetheless, which will lessen over time, as I mentioned previously.

I don't know anything about the Linux apps, so can't speculate about them.

Turns out you are quite correct about the number of units. Sort of confusing, bearing in mind that this machine covers some 15k of credits. All this for just 5 units seems a bit odd. Once again: this started only about a week ago. I never got these readings before, didn't change any settings, and it's the same host after all. And: applies to Win only - at least as of today. Guess I'll just hang in there waiting to see how the next units are going to do - give or take 3 or 4 days from now.

What is Astropulse?:

This machine:
http://setiathome.berkeley.edu/show_host_detail.php?hostid=6272174

... have:
SETI@home Enhanced 6.03 windows_intelx86 - Number of tasks completed - 175
Astropulse v505 5.05 windows_intelx86 - Number of tasks completed - 5

Every application have its own estimation

That is always a temporary problem.

There are three things you can do:

1) Add a few more BOINC projects to your mix (this will at least keep your CPUs warm).
2) Set a larger additional work buffer. After the outage recovery please.
3) Just grin and bear it. The problem will go away eventually (at least for a little while).
