Description

Hello,

I am running GPU tests suite from OpenCV 2.4.1 Win32 Build. The MeanShift test suite is showing 'launch-timeout' error. When this happens the Nvidia co-processor actually flashes the laptop screen and display a balloon message. It says something like it has been 'reset'. The failure of this test has a knock-on effect as the rest of the tests failed with 'unknown error (-217)'.

Is this a limitation to my GPU and Is there any way I could avoid this 'timeout' issue?

My NVidia 'card' is G310M. Capability 1.2.
CUDA v4.2.

Here is copied from the XML log:

<testcase name="Filtering/0" value_param="GeForce 310M" status="run" time="10.513" classname="GPU_ImgProc/MeanShift">
      <failure message="C++ exception with description "D:/OpenCV/Workspace/OpenCV2.4.1_Dev/modules/gpu/src/cuda/imgproc.cu:160: error: (-217) the launch timed out and was terminated
" thrown in the test body." type=""><![CDATA[unknown file
C++ exception with description "D:/OpenCV/Workspace/OpenCV2.4.1_Dev/modules/gpu/src/cuda/imgproc.cu:160: error: (-217) the launch timed out and was terminated
" thrown in the test body.]]></failure>

Thanks!
Frankie

This error is appear because your GPU has only 16 CUDA cores. If your kernel can't complete before CUDA driver timeout this error is resulted. Default timeout is 2ms. You can increase it. For more info please see answers.opencv.org post
