superlu_dist doesn't work in peysc-3.0.0-p1

[Ravi Kannan]

Hi,

After I upgrade the petsc from 2.3.3 to 3.0.0, I have made the change for
the superlu from
_ierr = MatSetType(_A,MATSUPERLU_DIST)
to
_ierr = MatSetType(_A,MAT_SOLVER_SUPERLU_DIST)

Is this the only change I need to do?

Ravi, X.G

    Hi
    Can the petsc parallel vectors be used with two different communicators?
For instance, I have created two different communicators called FEA_Comm and
FSI_Comm. The total number of processes are x+y. FSI_Comm works on x+y but
FEA_Comm works only on x.

    Now I am trying to create parallel vectors a1 and a2 such that a1 has
entries from x+y processes but a2 has entries from only y processes.

    After splitting the communicators I assign PETSC_COMM_WORLD to FEA_Comm
which works on only x processes. Subsequently petsc is initialized
(PetscInitialize()). But when the parallel vectors are created, the
processes hang.

  PETSC_COMM_WORLD should encompass all processes you wish to use in PETSc,
so that means x+y. You can create Vec
  objects on subcommunicators, like x.

    Any suggestions will be helpful
