I am new to Trilinos.
I am assembling a FEM CRS matrix in Epetra.
I have divided the matrix in row section by the number of available
Now when each process starts the Assembly of the global matrix it come to
the point where is has to update a row of the global matrix which does not
the process itself. Thus it cannot be added to that portion of the global
using matrix attribute methods etc. Rather I think I have to send this row
the matrix to the appropriate process to be assembled there. This involves
rather complicated MPI communications. What I am wondering is that there
be some kind of Export (Import) functionality for Epetra_Crs_Matrix to
the situation. Please advise !
