<hr />
<p>Asymmetric global function</p>
  <p>Constructor: ParRootFunction(|root_function|, 
  |other_function|=None)</p>
  <p>Arguments:</p>
  <p>Global functions are called with global object arguments. The local 
  values of these arguments are then passed to the local function, and the 
  result is returned in a ParValue object.</p>
  <p>A ParRootFunction differs from a ParFunction in that it uses a 
  different local function for processor 0 than for the other processors. 
  ParRootFunction objects are commonly used for I/O operations.</p>
