I found a solution to my problem through NVIDIA Developer Forum. If you wanna know more info regarding the solution check out this link.

In Short:

• When I changed the N = 32000 or any other smaller amount, it did work nicely.
• In fact, this means I am not compiling it in correct GPU type(check_cuda is the function call to verify it).

Hope my answer would help for someone.
