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?
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. Google is your friend, just search for "nvidia watchdog". [...]
Thanks, Partha
Tobias
