The C++ language interface for MPI is designed according to the following criteria:
 
 
 
2. The  MPI C++ language bindings provide a semantically correct  
  interface to  MPI.    
 
 
 
3. To the greatest extent possible, the C++ bindings for  MPI  
  functions are member functions of  MPI classes.  
 
Providing a lightweight set of  MPI objects that correspond to the  
  basic  MPI types is the best fit to  MPI's implicit object-based  
  design; methods can be supplied for these objects to realize  MPI  
  functionality.  The existing C bindings can be used in C++ programs,  
  but much of the expressive power of the C++ language is forfeited.  
  On the other hand, while a comprehensive class library would make  
  user programming more elegant, such a library it is not suitable as  
  a language binding for  MPI since a binding must provide a direct  
  and unambiguous mapping to the specified functionality of  MPI.  
 ( End of rationale.)
