title: CUDA max threads in a block
body: <p>I have a confusion from the programming guide . It states the following:</p>
  
  <ul>
  <li>maxThreadsPerBlock: 512</li>
  <li>maxThreadsDim: 512, 512, 64 .</li>
  </ul>
  
  <p>When max number of threads in a block can be 512, how can the max thread dimension be 512*512*64 ? </p>
