title: Best way to "warm up" the GPU with CUDA?
body: <p>I'm aware of the thread <a href="https://stackoverflow.com/questions/41098237/is-the-warmup-code-necessary-when-measuring-cuda-kernel-running-time">Is the warmup code necessary when measuring CUDA kernel running time?</a></p>
  
  <p>But even with the great internet, this CUDA book and the code samples that go with it available, I can't find an example of a warmup kernel.</p>
  
  <p>My question is: What is the best, cleanest way to "warm up" the GPU with CUDA before running experiments with timers? </p>
