实现MPI IO Stream

以流的方式实现IO会带来许多方便

 

class mpistream:public communicator

{

public:

        mpistream(int nsource,int nsourcetag,int ndest,int ndesttag);

        ~mpistream();

 

        template<typename T> mpistream & operator << (T&)  ;

        template<typename T> mpistream & operator >> (T&)  ;

 

ptotected:

       int  m_nsource;

       int  m_nsourcetag;

 

       int  m_ndest;

       int  m_ndesttag;

};

 

template<typename T> mpistream & mpistream::operator << (T& value) 

{

       send(m_ndest,m_ndesttag,value);

       return *this;

}
