Hi, PETSc developer

Now, when using MatGetSubMatrices(), the submatrices are saved in one cpu.
Sometimes, the dimension of the submatrices are huge, it is impossible to
save them in one cpu.

I am wondering whether the submatrices can be saved in parallel mode when
using MatGetSubMatrices(). thanks a lot.
