At the moment my systems as reporting results every 5 minutes. Is it possible to defer reporting 'till there are either more than a specified number to report or a specified time has passed please? I am typically reporting as below.

I tried adding <report_results_immediately>0</report_results_immediately> but this did not help.

In a tryical day I see 97 MB uplaoded and 286 MB downloaded. The amount uploaded is more than I was expecting and am wondering if reporting results every 5 minutes could be the reason it's so large.

I am using BOINC x64 V7.0.25. As I recall 6.12.34 used to do the same.

Since BOINC makes Scheduler requests only to Report completed tasks (and not requesting new tasks)
BOINC thinks it will not have Internet connection in the next XX days and is in a hurry to report while it can.

This depends on "Maintain enough tasks to keep busy for at least 10 days"
(if the deadline is in the next 10 days BOINC will report immediately)

So change your cache from e.g. 10+10 to 8+12 or 5+15 days.
(the values >10 for the second setting are not possible with the GUI (BOINC Manager) but it's possible to edit directly:
<work_buf_additional_days>XX.000000</work_buf_additional_days>
in global_prefs_override.xml
)

Also the setting "Switch between tasks every XYZ minutes" may affect this if set to big values (e.g. 15000 minutes)

The task switch interval is part of the computation of the computation deadline, but not part of the computation of when to actually report.

Thank you Bil, I have set <work_buf_additional_days>20.000000</work_buf_additional_days> which will help getting work when the DCF is stupid.

I have connect every 8 days set to force shorties to get run as they arrive so I have enought WUs cached to keep busy when the server is down. I will see what happens if I set zero tomorrow.

With BOINC 7.0.25 "zero" for the "connect every/Maintain enough tasks to keep busy" is not good, it will not ask for work at all.
(with 8+20 it will wait for the cache to be < 8 days, then will ask for 20 days)

John McLeod VII say "The task switch interval is part of the computation of the computation deadline, but not part of the computation of when to actually report."
so you can use this setting "to force shorties to get run as they arrive" instead.

Try "Switch between tasks every 14400 minutes" (which should make the shorties run at "high priority")

I will try <cpu_scheduling_period_minutes>14400.000000</cpu_scheduling_period_minutes> and see what happens.

I have now set <work_buf_min_days>0.000000</work_buf_min_days> but it's still reporting results every 5 minutes.

Is it possible that you have tasks that are over or very near the deadline?
(and you don't forget to "Read local prefs file" after manual edit?)

And "reporting results every 5 minutes" is not coupled with asking for tasks?

Looking at http://setiathome.berkeley.edu/results.php?hostid=6379672&offset=1573&show_names=0&state=1 4 Jun 2012 | 23:53:56 UTC is the soonest. The GPUs will totally empty the cache in four days and the CPUs in similar.

Remember for my systems the 400 + 50 limits are stupidly small.

I have discovered this is a "feature" from changeset [23571]. The word bug comes to mind.

You may propose changes/new value (-1) for <report_results_immediately>

(I don't know how, maybe direct email to David Anderson
http://setiathome.berkeley.edu/view_profile.php?userid=432107

He posted his email here:
http://setiathome.berkeley.edu/forum_thread.php?id=61471&nowrap=true#1037452
)

As you know now it is:
<report_results_immediately>0|1</report_results_immediately>
0 == Default value/behaviour (report results on several events)
1 == Force report_results_immediately

Propose:
-1 == Force Do_NOT_report_results_immediately (report results ONLY on events, e.g. "24 hours before deadline", "On a request for new work", ...)

Will this be accepted as needed/feasible I don't know.
