crush after a second run when using vast global memory


Anybody has similar experience?

My excutable run well the first time and got correct results, however, when run the second time, the machine will crush. When I reduce data size, I can run a few more times before crush.

I have carefully checked the memory allocation and free and I’m sure no memory leak in my code. ( I do use vast of global memory in my program ). I also checked to make sure, redundant thread won’t access the memory, so that there are no access confliction.

Any idea on this problem?
