I don't. Please provide what I say in my previous post.

I have to go for a few hours. I'll check back later.

Give me the output of :
ps -o cmd --no-headers -p $(pgrep setiathome)
and
nvidia-smi -q

Driver is 260.16 and CUDA App is: setiathome-6.11.x86_64-pc-linux-gnu__cuda32

I tried installing that driver but the NVidia installer is a pain, the xorg.conf it creates doesn't work (X crashes on start up) and the problem is too subtle for me to pick up quickly.

Will do but I'll have to reinstall the 2nd card first to get meaningful files. will post them tomorrow.

It's only BOINC that has a problem with the 2nd card, as a video device it work perfectly, desktop and movies are fine. The system and BOINC know there is 2 cards, it's only that both instances of the app run on the same card without realising it. I'm suspecting a weird bug in the app.

sunu:
Also what version are your cuda libraries?

2.6.33 is almost a year and a half old. Why don't you use a newer kernel?

Cos I work on the "if it ain't broke don' fix it" principal :) Plus I don't have the time to spend compiling kernels and drivers. Repository kernels may be slow updating but they work with a minimum of fuss (usually).

Driver Version         : 260.19.36


As I said Driver and app versions  ;)



The Xorg conf and log files are attached. There are no glaring errors that I can see. The video system works perfectly for movies and games. The only app that has any trouble with it is BIONC. It's a weird problem. I suspect it's a bug in the Linux app and the way it handles multiple instances running on multiple devices.

Under Windows, the same hardware runs without problems and both cards are used. Compare these 2 machines Windows and Linux . It's exactly the same hardware, only the HDD with the operating system was changed.

sunu:
Is this with only one GPU? Some quick notes:

1) Why do you run as root?
2) There is no "--device x" flag on the running app. Is this because of small terminal window? Make it bigger and recheck.
3) This isn't what I would expect from nvidia-smi. Sample ouput:

I don't remember how nvidia-smi behaved with 260.xx. As I said try a newer driver.

I'll check the xorgs later.
