Memory problem

Memory problem

Hi,

I'm running my rendering application, it is able to render a part of the image, but after "some" calls I got a "Memory problem"

Here is the problem :

C:\OpenCL\runtime\src\runtime\memory.cpp:104: guarantee(hostMem_ != 0)

For the OpenCL code, it is the same than the following post :

Hi,

Yes, it is this code... if you call the "OpenCL" code 800.000 times (Lik here) you get a memory problem.

I have try to play with and with some variations of the codeI still got the problem... really I can't find a way to fix it !

Feel free to contact me if I can help.

 

Thanks

Viewon01,

  could you please send us test case in C/C++ which reproduces the your problem as we are not familiar with OpenTK code? we did not get much runtime code information from your source.
