[petsc-users] Matload with given parallel layout

[Karin&NiKo]

Dear PETSc team,

I have a code that creates a parallel matrix based on domain decomposition.
I serialize this matrix with MatView.
Then, I would like to relaod it with MatLoad but not leaving PETSc decide
the parallel layout but rather use the original distribution of the degrees
of freedom.
Does MatLoad help to do that? Shall  I use the IS of the local/global
mapping ?

I look forward to reading you,
Nicolas
