cuda-gdb Xorg and gtx295

Accelerated Computing CUDA CUDA Programming and Performance
#1

Hello,

I have seen that now it exists a gdb version for cuda, which is a very interesting feature.
I tried it, but it doesn’t work under Xorg. Like I have a gtx 295 with two gpu, I would like to know whether it exists some way to use one gpu for X window system and the other for executing kernel and cuda-gdb ?
Currently I use cudaSetDevice(1), but this way doesn’t work (or I don’t use it properly).

Thank by advance.
Regards.

Ojjy

I have exactly the same problem, it would be nice if someone has a solution :)

Same here - I’d be very interested in this.

Is there some nvidia-official person who could comment on this?

Just make sure X is not configured to run on one of the cards and use the nvidia-smi utility to set the display card to be compute prohibited. After that it should just work (I have a development box with a pair of GTX275s set up like this and it have never given me any trouble).
