I have a question,
Is the input data of such kernel: kernel void mul(int width, double2 A, double2 B, out double2 result<> always destroyed (on GPU memory) after every invocation of that kernel or only when destroy the Stream object?
In my particular case I need call that kernel, say 20000x times and only data of "B" changes, "A" is always the same and that is why I am asking. Copying 20000x data of "A" within host memory and GPU memory is a waste of time in this case.
thanks in advance for the reply.

how to destroy a stream?
the application finished(not destroy the stream), run the application again, find the above running affected the current running.
Hi. I have a related question. I find that if I create and destroy large streams of increasing size in quick succession, the driver crashes and the OS (Vista SP2) blue-screens. It seems that GPU memory is not deallocated immediately when a stream is destroyed. Is this correct? When is GPU memory deallocated?
