[Trilinos-Users] Zoltan with Epetra_CrsMatrix

[UTSA]

You can certainly use Zoltan directly, but perhaps an easier solution is to use Isorropia and utilize the Epetra interface and perform a hypergraph partition of the underlying Crs_Graph for your matrix.  The example  packages/isorropia/example/matrix_1.cpp should give you a good idea of how to do this.

Hi, I have a question on Zoltan;
I am originally Epetra user not Zoltan user. Now, my program suffers from load unbalance. To solve the problem, I considering using Zoltan or not.
My program basically uses Epetra_CrsMatrix. The main trouble is that numbers of non-zero values in rows is quite different. Thus, certain row has too many non-zero values while the other value has less non-zero values;
Is this situation proper to use Zoltan? and Does Zoltan support Epetra_CrsMatrix? Because I’ve never seen the example that use Zoltan with Epetra stuff.
