title: Is there a way of setting default value for shared memory array?
body: <p>Consider the following code:</p>
  
  <pre><code>__global__ void kernel(int *something) {
  extern __shared__ int shared_array[];     
  
  // Some operations on shared_array here.
  
  }
  </code></pre>
  
  <p>Is it possible to set whole shared_array to some value - e.g. 0 - without explicitly addressing each cell in some thread?  </p>
