hello, I have compiled a library with GPU module in Win7 64 bit. I have tried an example gpu-example-surf_keypoint_matcher.exe. But the result was:

"Device 0: "Quadro FX 3700M" 1024Mb, sm_11 (not Fermi), 128 cores, Driver/ me ver.5.50/5.50 OpenCV Error: Gpu API call (too many resources requested for launch) in unk function, file D:/openCV/opencv/modules/nonfree/src/cuda/surf.cu, line 947"

Does anyone have an idea how to fix it?

Thanks reteP

This error means that you card doesn't have enough resources to launch the code.

You can fix this error only by SURF code modification - reduce thread block size, shared memory and register usage, etc. Or use newer card, because your card has old architecture (1.1) and the SURF was optimized for Fermi (2.0).
