Detailed Description

Epetra_Combine Mode enumerable type.

Enumeration Type Documentation

enum Epetra_CombineMode

If set to Add, components on the receiving processor will be added together. If set to Zero, off-processor components will be ignored. If set to Insert, off-processor components will replace existing components on the receiving processor. If set to InsertAdd, off-processor components will replace existing components, but multiple off-processor contributions will be added. If set to Average, off-processor components will be averaged with existing components on the receiving processor. (Recursive Binary Average) If set to AbsMax, magnitudes of off-processor components will be maxed with magnitudes of existing components of the receiving processor. { V = Supported by Epetra_Vector and Epetra_MultiVector, M = Supported by Epetra_CrsMatrix and Epetra_VbrMatrix }

Enumerator
Add	Components on the receiving processor will be added together. (V,M)
Zero	Off-processor components will be ignored. (V,M)
Insert	Off-processor components will be inserted into locations on receiving processor replacing existing values. (V,M)
InsertAdd	Off-processor components will be inserted into locations on receiving processor replacing existing values. (V,M)
Average	Off-processor components will be averaged with existing components on the receiving processor. (V)
Epetra_Max	Off-processor components will be maxed with existing components on the receiving processor. (V)
Epetra_Min	Off-processor components will be min'ed with existing components on the receiving processor. (V)
AbsMax	Magnitudes of Off-processor components will be maxed with magnitudes of existing components on the receiving processor. (V)
AbsMin	Magnitudes of Off-processor components will be min'ed with magnitudes of existing components on the receiving processor. (V)
Epetra_AddLocalAlso	Like Add but local components are also added
