Member Function Documentation

template<class T, class S> void communicator< T, S >::accumulate (  packed_vector< S > &  _x  )  [inline]

The accumulate procedure converts a distributed packed_vector to an accumulated packed_vector. Parameters: _x  Input: Distributed packed_vector, Output: Accumulated packed_vector.

template<class T, class S> void communicator< T, S >::accumulate (  vector< S > &  _x  )  [inline]

The accumulate procedure converts a distributed vector to an accumulated vector. Parameters: _x  Input: Distributed vector, Output: Accumulated vector.

template<class T, class S> void communicator< T, S >::collect (  vector< S > &  _t  )  [inline]

The collect procedure calculates the global sum of all input vectors. Parameters: _t  Input: Numerical vector, Output: Sum of all input vectors.

template<class T, class S> void communicator< T, S >::collect (  S &  _t  )  [inline]

The collect procedure calculates the global sum of all input values. Parameters: _t  Input: Numerical value, Output: Sum of all input values.

template<class T, class S> void communicator< T, S >::distribute (  packed_vector< S > &  _x  )  [inline]

The distribute procedure converts an accumulated packed_vector to a distributed packed_vector. Parameters: _x  Input: Accumulated packed_vector, Output: Distributed packed_vector.

template<class T, class S> void communicator< T, S >::distribute (  vector< S > &  _x  )  [inline]

The distribute procedure converts an accumulated vector to a distributed vector. Parameters: _x  Input: Accumulated vector, Output: Distributed vector.
