[petsc-users] Problem with large grid size

[Fazlul Huq]

Hello PETSc Developers,

I am trying to run the code (attached herewith) with the following command
and it works until the size of the matrix is 99999X99999. But when I try to
run with 999999X999999 then I got weird result.

The command is:
./poisson_m -n 999999 -pc_type hypre -pc_hypre_type boomeramg
-ksp_view_solution
Any suggestions is appreciated.

Thanks.
Sincerely,
Huq
