stupid question.. what sets boinc's timing to report completed workunits?

There's a whole long list of possible triggers (see John McLeod VII's post at SETI for all the gory details), but in general no 'ready to report' task should hand around on your computer for longer than 24 hours. So they should disappear at least once per day without you doing anything.

ok i wont touch it and wait till this time tomorrow to look to see if it has reported.
will check out that reference. thanks!

The BOINC FAQ Service has very similar info in http://boincfaq.mundayweb.com/index.php?language=1&view=68, though jm7 has been more directly involved in the scheduling code development and lists things a little differently.

it run very well know i have got my firsts valids WUs on my GTS250 (about 5~10 min for a WU).It use about 2 % of CPU time to run so that i can crunch 2 other seti WU on my C2D E7300.
Bye

After crunching other projects for some months, I restarted SETI@GPU just his morning, but using the initial CUDA build for Linux which uses 100% of one CPU core as well...
So these new versions, that can be found in crunch3rs board, will use only few % of one CPU? That would be awsome...
I'm currently still at 180.60, some 2.6.30 rc and 6.6.17, but willing to update if I could free up that core with a never version of the app :)

I can confirm that setiathome-6.08.CUDA_2.2_x86_64-pc-linux-gnu no longer takes 100% CPU (only about 2-4% now on this PC). That's with CUDA 2.2 - I haven't been brave enough to upgrade to CUDA 2.3 yet. Also using nVidia 185.18.14 and BOINC 6.9.0. The only downside so far is that the CPU time column now only shows actual CPU time used which is only a couple of minutes during the 19 minutes CUDA run. So no good way of checking exactly how long a WU takes now unless I monitor the clock manually.
