SETI MB CUDA for Linux
riofl:
ok. i am going to have to get down to some very serious diagnostics here. the gtx 295 exhibits the same trouble as the 285 does on port1 !!!!!! yet a gts250 does not... or on that one boot it didnt. i have asked my friend to bring it back when he can stay a while and i can try multiple reboots. funny thing is when the 285 is in alone, it always picks port1.
its the oddest behavior i have ever seen. i enabled the 3 monitor setup which works, but its a lottery which screen will become 1600x1200 with each reboot now. mostly it sticks to device 0 dfp1 , 2nd port... but it has done this to all 3 ports and screens!! i'm baffled.. i am sending msgs off to everyone involved in the entire video display chain to see if anyone has some ideas.. i am including gigabyte in this too although i dont know how the mobo can affect it.
i put the 295 as the first device to use and the 285 in the 2nd slot.. its weird but the 295 is actually slower in video response than the 285 is. however all 3 gpu chips crank cuda out very nicely. the 285 is a bit faster there too. i guess they had to go with slower, cooler gtx275 setups in order to be successful in dual gpu in a single box. temps are good in this pupppy though. so far they have not exceeded 65c under heavy load! of course i have the fan set to 100% :P i think it was asus or acer that made a limited edition dual 285 card.. expensive tho. also only made 1000 of them.
looks like i have a while of brain burning diagnostics ahead of me... hehe i think a phd in astrophysics would probably be easier. at least that course is ordered and logical :)
sunu:
The xorg.log would be quite useful to your troubleshooting.
The 2 gpus used in a gtx295 are weaker than the gpu in gtx285. They are not even equal to a gtx275. They are downclocked gtx275s.

maybe i will switch them then and put the 295 in the 2nd slot. the slower screen updates and pausing are getting to me. didnt do that with the 285 and tesla.

I have a GeForce 8800 GT. Whats wrong here ? :(

For windows version I would propose to update drivers. No idea if it applicable to Linux...

I've been recently bitten by this very same problem. Im my case it seems that I've got too recent NVIDIA drivers (version 256.35, cudatoolkit 3.1).
I'm running 32-bit ubuntu 10.04 on Q6600, 8GB RAM and GeForce 8600 GT. I'm not running graphical user interface (X server might be running though), BOINC 6.10.17 says
--- Code: ---NVIDIA GPU 0: GeForce 8600 GT (driver version unknown, CUDA version 3010, compute capability 1.1, 255MB, 99 GFLOPS peak)
--- End code ---
Any suggestion? 64-bit linux on this machine is out of question due to unrelated reasons.
sunu:
What seti app do you use?
Also a link to your machine would be nice.
With 8 GB RAM may I ask why 64 bit is out of the question?
