Shri, Could you please add the support for this? And push to petsc-dev Thanks Barry On Sep 1, 2010, at 10:23 AM, Leo van Kampenhout wrote: Using a DA, of equal size and type as the other one. The curious thing is that there are no problems on a single core run.

The MatLoad() does work perfectly on a single core, however two or more cores make the program crash with the following error (see below) > > The programcall is mpirun -n 2 ./main Is something broken with Petsc or do I need to set some extra parameters? > > Thanks in advance, Leo van Kampenhout PS.
