seems to refer to sequential vectors... well I think
I'm freeing everything I've created unless I misunderstood something ?

Hello,
I have a code that uses the DMMG objet for a linear problem. The DA I
create for the coarse grid is DA_XPERIODIC and 2D. I let petsc decide
for the number of processors in each direction.
I have a problem which depends on the number of processors I use.
If I want a 1024x1025 grid with 4
size.

Ok that's it for the moment,

Dear all,
I have a simulation code (particle in cell) in which I have to solve a
linear vector equation 4 times per time step. A typical run consists
of 50 000 time steps. The grid is rectangular and uniform of size Lx,
Ly, with nx+1 and ny+1 points in the x and y direction respectively.,
