<P>
Package edu.rit.pj.reduction contains classes for parallel reduction.
<P>
Class <A HREF="Op.html">Op</A>
is the abstract base class for a binary operation
used to combine two values together during a reduction.
The subclasses of class <A HREF="Op.html">Op</A>
provide binary operations on different data types:

<P>
Each of these subclasses provides an <TT>op()</TT> method
that can be overridden to compute the desired binary operation.
Each of these subclasses also provides static instances
for commonly-used binary operations
like sum, product, maximum, and minimum.
<P>
The following classes provide shared reduction variables
for each of the primitive types as well as type Object.
These classes are intended to be used
in an SMP parallel program
for data items shared among all the threads in the program.
