Does Windows count running on a UPS batteries as being "on batteries" the
same as a laptop? If it does, then it would work the same as a laptop.
Attempting to report work that is completed (no work requests) does make
sense as it might be a long time before there is another chance (even makes
sense for laptops that do not allow work on batteries). Having a short
delay also makes sense as I have seen the power go off, on, off, on, off,
on within the space of a few seconds (if computation is running, don't turn
it off for a few seconds when switching to batteries, and if not running,
don't start computation for a few seconds when coming off of batteries).
It would be nice if they were user configurable.

[boinc_dev] UPS support in BOINC

To BOINC devs,
I was wondering if anyone knows if boinc could be made to have greater
options to change how it (or more accurately the science apps) runs while
the machine is on uninterrupted power supply (UPS) battery power as opposed
to normal power. I am not a developer and do not know how to go about
doing this. I just wanted to describe the behavior I want of boinc below
and see if it is doable:
I currently have BM 6.10.17 on my MacOS 10.6.2 Intel 64-bit Mac Mini
(2.0GHZ Intel Core 2 Duo, 2gigs RAM). I live in a rural area where the
power lines get knocked out relatively frequently, and I recently got the
sense to invest in a UPS (BELKIN-F6C-550-AVR REV. A). The monitoring
software I use is Belkin Automatic Power Software V2.5.02, which is
cross-platform but quite archaic. It uses a USB connection to the device.
Are there hidden UPS options in BOINC somewhere? I want the following to
happen:
When the computer has been on UPS power for greater than 5sec OR the
battery is less than 60% full, suspend all projects AND put all projects in
No New Tasks mode. When the comp has been on UPS power for greater than
one minute OR the battery is at 50% or lower, run the update command on all
projects (this way the completed ones can be uploaded before system
shutdown.) I plan to get battery backups for my network equipment someday.
Once the update command for all projects has finished shutdown boinc.
System shutdown is at 30% battery power.
I am aware that the software for dealing with UPS is inconsistent across
operating systems and UPS manufacturers, but I think that this improvement
to boinc would be really useful. Even if you can't support my specific
situation I think a lot of people would be grateful if future releases of
boinc had even basic compatibility with the built-in UPS software most
operating systems have now.
Sincerely,
Jack Lambert
