True, but I got the same for the newer, just picked one from the error list, didn't notice its the old one...
--- Quote ---Did you update your app_info.xml? Also make sure you copy the new libcudart.so.2 and libcufft.so.2 to your projects/setiathome.berkeley.edu directory.
And finally, as stated in another thread, also copy the new executable to /usr/local/bin or whatever directory you have in your PATH. I have had no problems since following these advices (well, apart from having to renice the executable to level 0 to give it enough CPU time).

Yes, I did all that. Anyway, it seems to be running now, due to not making one change at the time, I don't know what was exactly the cause. ;) ::)
Besides, its just first WU, hopefully there will be no more errors.
edit: It works. Finally :)

one thing you need to make sure of is that the project directory where the cuda libs are is listed in the ld.so.conf file and that you have run ldconfig. without that it is very likely it would crash possibly a few times and then find its libraries by accident.

Yeah, I always verify DSO availability with ldd on every client ...

riofl, what is happening?
I've checked again your host today and I've seen this: http://setiathome.berkeley.edu/results.php?hostid=4166601&offset=40&show_names=0&state=2
All 2 hundred and 3 hundred sec tasks were done by your 285. All two-digit sec tasks were done by your tesla. This is completely abnormal.

i have no idea. i agree unless my desktops are keeping too many shaders busy which i dont think standard gui desktops use many of them if at all then i am at a loss... the 285 should be at least near the speed of the tesla allowing for the 285 to be busy with things on the desktops. since we have had some strong storms in the area boinc has been down for the past 3 hours or so and i have just started things back up.
i think maybe i will boot this machine from my tuning windows drive tomorrow (keep it in a drawer) and review what riva tuner and the evga program tell me. nvidia-settings shows me that all the clocks meet what they are supposed to be. now i dont know about desktop settings much but there is one change i made in the past few weeks with nvidia-settings. i unchecked Sync to VBlank in xvideo settings and also unchecked sync to vblank and allow flipping in the opengl settings. wasnt sure what they did but there seemed to be no difference. should they be checked? out side of that, the clock freq on the 285 are as follows
2D settings gpu 300mhz memory 100mhz
3D settings gpu 690mhz memory 1300mhz
power mizer which seems to not have settings says adaptive clocking enabled performance level2 perforamce mode desktop. level2 is the 3d settings above however i remember when i first got the card, performance mode said maximum performance and somewhere along the line it changed to desktop. since the other settings are the same i can only assume it is a function of which driver is being used for which text shows up.
does this give any clues?

Hi.
I was just wondering if there are any known issues in using the CUDA client with the 2.6.30 kernel ? I recently built a 2.6.30 kernel (to see if the AP units will fail), and noticed that my CUDA units were appreciably slower (taking over an hour).
I just switched back the latest ubuntu kernel (2.6.28-15-generic), which seems to work fine.
Any suggestions, any particular info you need ? I'm using the same nvidia driver in both cases (185.18.31, on an x86_64 platform)
