Is that possible to use the PETSc-MMA with the overlapping Schwarz domain decomposition (DM) algorithm.

Thank you for the development of the PETSc-MMA, and making it available on Github. I am using  the overlapping Schwarz domain decomposition (DM) algorithm, and I am trying to build your MMA as a dynamic library and link it to my code. However, I have an issue. My understanding is that in your parallel framework the domain decomposition method results in several sub-domains without an overlapping area. But in the overlapping Schwarz domain decomposition algorithm there are overlapping areas. When I tested your MMA, it behaves well with 1 thread under DM algorithm, while the more threads yields wrong results.
I was wondering if it is possible to use your PETSc-MMA with DM algorithm. Thank you in advance for helping me with this question.
