[Trilinos-Users] Problem with Epetra_Import

[Baker, Christopher Grover]

Massimiliano,

Did you check that the return code from MatrixBalanced->Import() into ierr is zero on all processors?

Hello,

I'm trying to use Epetra_Import (Trilinos 9.0.3) but I have a strange
behaviour.

This is the piece of code I'm using:


Epetra_Import Import( *BalancedMap , *UnbalancedMap ) ;
Teuchos::RCP< Epetra_VbrMatrix > MatrixBalanced ;
MatrixBalanced = Teuchos::rcp( new Epetra_VbrMatrix( Copy, *BalancedMap, 0 ) )
;
err = MatrixBalanced->Import( *MatrixUnbalanced , Import , Insert ) ;


In which MatrixUnbalanced is build upon UnbalancedMap and are correctly filled.

In MatrixBalanced appear some column indices that are either negative or very
big...Maybe a problem with signed/unsigned integer conversion?

In attachment the output of MatrixUnbalanced, Import and MatrixBalanced for a
run with 2 processors.


Thank you very much.

MM
