virtual bool	reweigh (GridObject *conn)
virtual	~ICommunicationWeights ()

Detailed Description

Interface for the definition of weights for connections between elements. These weights introduce a customizable penalty for any side if the border of a partition includes the side. This can be used to minimize communication cost e.g. when using the ParMetis partitioner. It can also be useful if you want to make sure that certain subsets are not contained in any partition boundary or if you want to enforce that a collection of elements be in one single partition.

Member Function Documentation

get_weight()

virtual number ug::ICommunicationWeights::get_weight ( GridObject *  conn )

pure virtual

Get the weight of a specific connection.

Parameters

conn	pointer to the connection in question

Returns

weight for the side

reweigh()

virtual bool ug::ICommunicationWeights::reweigh ( GridObject *  conn )

inlinevirtual

Whether or not the given connection is to be assigned another weight. If true, this weight can be obtained by get_weight(), if false, no such weight must be requested.

Parameters

conn	pointer to the connection in question

Returns

true iff get_weight() can provide a new weight for the connection
