GPU API call (out of memory) problem when running code in pthread.

edit

Hi all,

I got the following error:

Opencv error:GPU API call (out of memory)

when i run the code in pthread I got the above error, say for 1000 iterations. When I run pthread, for say 10 iterations, there is no error.

I checked that there is no error in pthread. The problem is in deallocation of GPU memory. How do we have to do that?

Using Nvidia Quadro FX 3800 ,CUDA 5.5 toolkit (latest version)
