Hi Victor,
Sorry for the delay in responding. Like I told you the other night on gtalk, I am unable to get a log on Windows even using g_print as you suggested instead of g_message. On the Mac, I simply get that opencl is not being used since there is no shared object to load.
I think a lot of users will be using a single display (like I do using my laptop) and so, there would have to be some viable solution to problem of the nvidia driver killing the GPU job, don't you think?
I didn't know about the GEGL_SWAP= RAM option and will add that to the environment while running Gimp.
Thanks!
Partha

Hi Partha,I couldn't really reproduce your error, so I assume it is because you're trying to use the display GPU for processing and to avoid blocking the screen, the nvidia driver just kills whatever is running in the GPU.Also, I'm not sure if you're already using the GEGL_SWAP=RAM option to run GIMP, it should improve performance and maybe you don't get this error.On Sat, Feb 16, 2013 at 12:29 AM, Partha Bagchi <partha1b@xxxxxxxxx> wrote:Hi Victor,I have an NVIDIA GPU with 1G dedicated VRAM, i7 Core CPU, and 16G of RAM. In any case, 150x150 radius should be doable. In any case, I am sure that when Gimp goes production, it's bound to come up.Any further report on Mac? While I am finding that it's quite fast on an Mac with 8G RAM, I am not sure if the GPU is being used.Note that everything I have seen/ read about OpenCL says that you don't need to load the library at least on a Mac.Thanks,

Hi Partha,Thanks for the bug report, I'll give a look when I can.Notice that a 150x150 radius is very big and maybe yout GPU doesn't have enough memory for that, but it was supposed to fallback to the CPU in this case.ThanksVictorOn Fri, Feb 15, 2013 at 8:47 AM, Tobias Ellinghaus <houz@xxxxxx> wrote:

monitor connected. On Windows it will time out quite quickly, on Linux AFAIK
not. However, that can be configured. Google is your friend, just search for
"nvidia watchdog".
