Yes but in the documentation it should be clear that if the global
indices are not contiguous in each process, even if the memory is
locally contiguous in each process, then there will be communication to
build the matrix and the vector.

Sorry but I don't want another partition, Petsc internally is changing
the partition. I would like to have the same partition that I have in
the application. Is the example not clear?

Hello,
if I create an application ordering using AOCreateBasic, should I
provide the same array for const PetscInt myapp[] and const PetscInt

Thanks in advance for the help.

Hello,
I'm
not a big issue, but after solving the linear
system I get the solution vector x and I want to get the values in the
correct processes. Is there a way to get vector values from other
processes or to get a mapping so that I can do it myself?

th log and
debugging set to 0 so this should be fine.
Do you know about a branch that support this kind of issue or a way to
solve it?
