Detailed Description
template<class TAlgebra>
class ug::ComPol_MatDistributeDiag< TAlgebra >
Communication Policy sending fractions to.
This Communication policy assumes that the matrix is stored additively with no overlap. It then copies the row entries of the slaves indices to the corresponding master rows. Only those values are copied that have if the index the slave couples to has also a representation on the other process. This means that couplings to inner indices or to other slave/master, that have only connections to other processes, are not taken into account.
- Template Parameters
-
TMatrix matrix type

Member Function Documentation
◆ begin_layout_extraction()
|
inlinevirtual |
signals the beginning of a layout extraction.
the default implementation returns true and does nothing else. This method is only called on processes which extract data.
Reimplemented from pcl::ICommunicationPolicy< IndexLayout >.
◆ collect()
|
inlinevirtual |
writes the interface values into a buffer that will be sent
done
Implements pcl::ICommunicationPolicy< IndexLayout >.

◆ extract()
|
inlinevirtual |
writes values from a buffer into the interface
done
Implements pcl::ICommunicationPolicy< IndexLayout >.
References pcl::OrderedInterface< TType, TContainer, TAlloc >::begin(), ug::Deserialize(), pcl::OrderedInterface< TType, TContainer, TAlloc >::end(), pcl::OrderedInterface< TType, TContainer, TAlloc >::get_element(), ug::ComPol_MatDistributeDiag< TAlgebra >::m_rMat, and PROFILE_BEGIN_GROUP.
◆ get_required_buffer_size()
|
inlinevirtual |
returns the buffer size
This function returns the size of the buffer needed for the communication of passed interface. If the vector has fixed size entries this is just the number of interface entries times the size of the entry. In case of a variable size entry type a negative value is returned to indicate that no buffer size can be determined in advanced.
- Parameters
-
[in] interface Interface that will communicate
Reimplemented from pcl::ICommunicationPolicy< IndexLayout >.
References pcl::OrderedInterface< TType, TContainer, TAlloc >::size().
