It is returned by MatGetInertia(F,&nneg,PETSC_NULL,PETSC_NULL);

Note that this is INFOG(12), not INFO(12), so it is supposed to be a global
number. I don't really know the semantic difference between these, since
MUMPS has this insane interface that scatters the whole right hand side to
rank 0, and does not synchronize all diagnostics to all ranks, so it's not
clear that there is any way to access separate numbers for each process.
