<!-- ==================== CLASS DESCRIPTION ==================== -->

</pre>
<hr />
<p>Global class</p>
<p>Global classes are needed to construct global objects that have more
functionalities than offered by the ParValue class hierarchy. When an
instance of a global class is generated, each processor generates an
instance of the local class that becomes the local value of the new
global object. Attribute requests and method calls are passed through to
the local objects and the results are assembled into global objects
(ParValue or ParFunction). The arguments to methods of a global class
must be global objects, the local class methods are then called with the
corresponding local values.</p>
<p>The local objects are initialized via the special method __parinit__
instead of the usual __init__. This method is called with two special
arguments (processor number and total number of processors) followed by
the local values of the arguments to the global object initialization
call.</p>
<p>The local classes must inherit from the base class ParBase (see
below), which also provides communication routines.</p>
