Hi Guys,
I am able to compile my GPU code and run it. However, my code crashes after a few iterations with the following error under. I am calling my gpu kernel from a function that allocates gpu memory, calls the kernel, copies the results back to the host memory and finally "cudaFree"s the gpu memory.
*** buffer overflow detected ***: ./gpumuscle terminated
