When I was debugging my code, i got this error
[b]"Warning: all GPUs are used for X11 and cannot be used by while debugging.
Cuda error in file ‘cuda_test2.cu’ in line 51 : no CUDA-capable device is available.
Program exited with code 01."
[/b]
is that because currently cuda gdp does not support 64 bit Linux yet? I am using ubuntu 9.04 64 bits
Thanks!
No, its because all GPUs are used for X11 and cannot be used by while debugging. This is documented in the release notes.
No it means precisely what it says (and precisely what is written in the cuda-gdb linux readme file). You cannot run cuda-gdb on a card that has an active X11 display on it.
Oh OK! Thanks for the answer!
So does it mean if i would like to debug i have to stop all X11’s or have one extra graphics card?
Thanks a lot!
