system with iterative algorithm is to
load balance the non zero value between processors, so we have to use
weight, number of non zero value in the row, to have a good partitioning.
Do i have it right ?

I'am no longer talking about doing LU factorization. But use iterative
method for solving a linear system, like bicg. Like in the ex10. In this
example i don't understand why using MatPartitioning.

Dimitri,
No, I think this is not the correct way to look at things. Load
balancing the original matrix is not neccessarily a good thing for
doing an LU factorization (in fact
for sequential matrices in 16.2 of
manual, disturb me. What does it means ?
Best regards
