I added that option but the code still gets stuck at the same call
MatZeroRows with 3 processors.

What sort of physics are in splits 0 and 1?
SOR is not a good GPU
Hi Folks,
I am using MatZeroRows() to set Dirichlet boundary conditions. This works
fine for the serial run and the solver produces correct results (verified
through analytical solution). However, when I run the case in parallel, the
simulation gets stuck at MatZeroRows(). My understanding is
It looks like we don't have a Fortran interface for this. In the
source code:
2366: Developer Note:2367: This is labeled with C so does not
automatically generate Fortran stubs and interfaces2368: because it
requires multiple Fortran interfaces depending on which arguments are
scalar or
This is fixed in branch

Dear PETSc team,
We are using the latest petsc version 3.20.1, intel compiler 2023,
and we found the following problem:
We want to call the function MatGetValuesLocal to extract a block sub-matrix
from an assembled matrix (e.g. a 5x5 blocked sub matrix). We use the matrix
format MatCreateBAIJ
