David,
This is ugly but should work. BEFORE reading in the matrix and right hand
side set the LOCAL sizes for the matrix and vector. This way you can control
exactly which rows go on which process. Note you will have to have your own
mechanism to know what the local sizes should be (fo

I ran into a case where using MUMPS (called via "-ksp_type preonly -pc_type
lu -pc_factor_mat_solver_package mumps") for a particular solve hangs
indefinitely with 24 MPI processes (but it works fine with other numbers of
processes). The stack trace when killing the job is below, in case that
