(this may not be Mac specific)

Is it common for finished tasks to pile up to 3-5 before uploading?

Tho I've noticed in the boinc client messages the "no work" and similar messages about the server possibly being down, the general order of business in task log otherwise has been d/l task, run, finish, upload, repeat.

Update project has cleared them, but if I were to leave town for a while, would hate to have the scheduler reissue tasks already finished...

(not so concerned at my current scale, but more powerful crunchers are on the way)

Let me quote John McLeod VII

Reports happen at the first of:

1) 24 hours before report deadline.
2) Connect Every X before deadline.
3) On the completion of upload if later than 1 or 2.
4) On a work request.
5) On a trickle up request (not all projects do this).
6) On a trickle down request (not all projects do this).
7) On a server requested schedule
8) With any other work that is being reported.
9) When the user hits the update button.

Gundolf

Uploading or reporting? I ask, as uploading and reporting is a two step program.

Uploading will happen immediately on a task being finished, as long as you gave BOINC network access. Reporting will happen after 24 hours, to try to get as many finished tasks in the report as possible.

Uploading doesn't take (much) overhead, as it's essentially writing a little bit of data on the server's hard drive. Reporting happens to the database, where reporting one task takes as much overhead (CPU, memory, database reads and writes) as reporting more than one task does. So the preference is to report more than one task.

Uploads can stall when Seti has a server outage, like during their weekly outage on Tuesday and the recovery period afterwards.

As it's in the BOINC client, I assume it's uploading - they sit at 100%, and each other task in the list will just finish out, they don't disappear from the client until I manually hit update - tho I've not let it sit at length yet (more than a day).

Does what Gundolf described "reports happen at the first of:" mean BOINC would clear these stalled files out eventually, or would it still require manual intervention (click project update) to clear it all and get back on track?

You may also want to set your Account Preferences to keep 1-2 days of work on hand. If you have more powerful hardware on the way, it will keep you crunching while the server is down.
I have seen work stay around for more than a day when they are having server problems, but as long as I have work to do, I don't worry about it. Sooner or latter it gets cleared.

Yes, it would, and they are not "stalled", they are "Ready to report" (according to the Status column). So, no manual intervention is needed.

Thanks for info Gundolf,

[off topic]Where's "international" for you, Steve? :-)[/off topic]

I just haven't set up a profile yet, I'm in the USA, tho from an ETI's perspective I guess I might be international - (would an ETI recognize political boundaries?) :-)

I plan on setting up a profile once the new rigs and network are set up, but I'm not in it for the credits exactly, other than making sure they are valid for the research projects. Just trying to learn as much as I can for now.

Thx and Regards

Your country isn't (necessarily) a part of your profile, it's an entry in your account (accessible via "Change other account info").

I like those little flags in the author's info box, and there's none for "international" :-)

Gundolf
