Using -pc_jacobi_rowmax or -pc_jacobi_rowsum

[Nguyen, Hung V ERDC-ITL-MS]

All,

I tried to use the jacobi preconditioner with maximum entry in each row as
the diagonal preconditioner and got the error message below. The matrix was
built with mpiaij type. Does it require different type of matrix? 

Thank you.
