Detailed Description

EpetraExt_Redistor: simple class to facilitate redistribution of Epetra_DistObject's.

EpetraExt_Redistor: a simple class to facilitate the redistribution of Epetra_DistObject's. An example of use of this class is the redistribution of matrix, LHS and RHS from a given map, to another map, so that the given DistObject can be converted to a non-epetra format:

• objects on non-linear maps can be mapped to linear maps;
• objects distributed on N-processors can be redistributed on a linear map on M-processors.

Constructor & Destructor Documentation

EpetraExt_Redistor::EpetraExt_Redistor (  const Epetra_BlockMap &  SourceMap, const int  NumTargetProcs )

Initializes object from SourceMap, to linear map defined on the first NumTargetProcs processors. Initializes object for redistributions from SourceMap, to a linear map (with the same number of elements), defined on the first NumTargetProcs.
