do PETSc examples compile/run correctly? What do you get for:
cd src/ksp/ksp/examples/tutorials
make ex2
make ex2f

Thank you in advance!

You need to take the PetscInitialize() out of the subroutine and instead
call it once at the beginning of your program.

I put PETSc solver in one function and use another function to call that.This
problem only appears when I put the function with PETSc solver in a loop,
it works well at first step, and reports error An error occurred in
MPI_Comm_rank after MPI was finalized
at second time. The program is designed
yes, exactly

You can try to run sole MPI samples coming with OpenMPI first, make sure the
OpenMPI is running all right.

I tried OpenMPI build PETSc and used mpirun
I am a beginner of PETSc.
I tried the PETSC example 5(ex5) with 4 nodes,
However, it seems every nodes doing the exactly the same things and
output the same results again and again. is this the problem of petsc or
MPI installation?
Thank you in adcance!
