what will happen if I do this:
suppoose foo1 and foo2 are two kernels.
now, I sent foo1 and foo2:
does foo1 still running when I sent foo2?
how can i make foo1 and foo2 copoeratoering?
I means some grids are excuesing foo1, and others are excuseing foo2 at the same time.
and, If i didnot cufree() the device memory which i cumalloced in my application, will it stay in the device forever? I think the device memory deosnot get protection from the operator system.
