[Gimp-developer] GEGL Crashes GPU
Hi Victor, Latest git. I have an NVIDIA GeForce GT 230M card with 1G VRAM. The opengl version is 1.1 CUDA 4.2.1 etc. Windows 7 64bit I think OpenCL is taking down my video every time. Here is a simple repeatable test for me. 1. Open 16 bit tiff. 2. Duplicate layer. 3. Layer - desaturate -> invert 4. GEGL gaussian blur x = y = 150. Takes the screen down (goes black and recovers) and leaves a dark tile on the layer. Any ideas? Also, As I was mentioning to you before: $ ls -al /c/Program\ Files/NVIDIA\ Corporation/OpenCL/ total 116 drwxr-xr-x 2 partha Administrators 0 Feb 3 22:55 . drwxr-xr-x 11 partha Administrators 4096 Feb 3 22:55 .. -rwxr-xr-x 1 partha Administrators 53024 Jan 28 17:39 OpenCL.dll -rwxr-xr-x 1 partha Administrators 61216 Jan 28 17:39 OpenCL64.dll OpenCL64.dll seems bigger. So, should that be the default DLL for windows 7 64bit? Thanks, Partha ___ gimp-developer-list mailing list gimp-developer-list@gnome.org https://mail.gnome.org/mailman/listinfo/gimp-developer-list

That is normal when running OpenCL (or CUDA) kernels on a GPU that has a monitor connected. On Windows it will time out quite quickly, on Linux AFAIK not. However, that can be configured.

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.

Re: [Gimp-developer] GEGL Crashes GPU
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.

Re: [Gimp-developer] GEGL Crashes GPU
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.

Re: [Gimp-developer] GEGL Crashes GPU
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!
