Usually when I meet a SEGV error, I will run it again with a parallel debugger
like DDT and wait for it to segfault, and then examine the stack trace to see
what is wrong.
Can you compress your matrix and upload it to google drive, so we can try to
reproduce the error.

Hi Matt,Thanks for your reply. We have got to a consensus. For
such a problem, I have sought the mail list for helps and found a great

Now I have overcome this by creating a PetscSF and PetscSFBcast, and

I switched from local array based value setting for initial conditions to
VecSetValues when converting the uniprocessor example to an MPI program.
While I removed VecRestoreArray and swapped u_local[*ptr] assignments with

Hi,
I have the following 2 lines in a function in my code :

The VecCopy fails with the error message :
[0]PETSC ERROR: Object is in wrong state
[0]PETSC ERROR: Not for unassembled vector
