Hi, I have a dense matrix of size 127200x168 over 2 MPI, so that means a have 63600 rows in on MPI process and 63600 in the other. Now When I use MatGetLocalSize in rank 0, it says that the number of local rows is 63600, but the number of local columns is 84, should not be 168?? Is this a bug??

Thanks
