title: In which case/senario should I use GPU( instead of CPU) to run my program?
body: <p>UPDATE: OK I will try to write some code and find out.</p>
  <hr />
  <p>If I have a program which runs like this:</p>
  <ol>
  <li>it picks 20 words from a dictionary each time. ( This dictionary contains 100,000 words)</li>
  <li>it combine this 20 words into a sentence. (e.g. <code>good cats are always nice to me</code>)</li>
  <li>it run a local function ( e.g. There is a local Class which defined a method, e.g. <code>MyTool.validate_sentence(&quot;good dogs are always nice to me&quot;)</code> )</li>
  </ol>
  <p>will this be run faster if using GPU?</p>
  <p>programming language is C/Rust.</p>
  <p>thanks a lot!</p>
