title: Is there anything in Java close to the parallel collections in Scala?
body: <p>What is the simplest way to implement a parallel computation (e.g. on a multiple core processor) using Java. 
  I.E. the java equivalent to this Scala code</p>
  
  <pre><code>val list = aLargeList
  list.par.map(_*2)
  </code></pre>
  
  <p>There is <a href="http://gee.cs.oswego.edu/dl/jsr166/dist/extra166ydocs/">this library</a>, but it seems overwhelming.</p>
