<P>
In this chapter, we have learned about a programming language,
CC++
 , that provides a small set of extensions to C++
  for specifying
concurrency, locality, communication, and mapping.  CC++
  does not
support the task and channel abstractions of Part I directly, but its
constructs can be used to build libraries that provide these
abstractions.  In keeping with the design methodology of
Chapter <A HREF="node14.html#chap2" tppabs="http://www.dit.hcmut.edu.vn/books/system/par_anl/node14.html#chap2">2</A>, CC++
  allows mapping decisions to be changed
independently of other aspects of a design.  The performance modeling
techniques of Chapter <A HREF="node26.html#chapperf" tppabs="http://www.dit.hcmut.edu.vn/books/system/par_anl/node26.html#chapperf">3</A> and the modular design
techniques of Chapter <A HREF="node39.html#chapmod" tppabs="http://www.dit.hcmut.edu.vn/books/system/par_anl/node39.html#chapmod">4</A> also apply directly.
Table <A HREF="node64.html#tabccsum" tppabs="http://www.dit.hcmut.edu.vn/books/system/par_anl/node64.html#tabccsum">5.1</A> summarizes the language constructs that have
been introduced.
<P>
The CC++
  programs presented in this chapter tend to be more verbose
than the equivalent Fortran M, High Performance Fortran, or Message
Passing Interface programs to be presented in the chapters that
follow.  To a greater extent than these other systems,
CC++
  provides basic <em> mechanisms
 </em> that can be used to
implement a variety of different parallel program structures.  For
example, we must implement a channel library in order to use channels
in a CC++
  program, and a processor object array library to create
arrays of processor objects.  Once these libraries have been
written, however, they can be reused in many situations.  This reuse is
facilitated by the object-oriented features of C++
 .
