title: Any particular function to initialize GPU other than the first cudaMalloc call?
body: <p>The first cudaMalloc call is slow (like 0.2 sec) because of some initialization work on GPU. Is there any function that solely do initialization, so that I can separate the time? cudaSetDevice seems to reduce the time to 0.15 secs, but still does not eliminate all init overheads. </p>
