SuperLU is not parallel, it does not work with mpiaij matrix.
Did you modify the runex52_superlu rule in the makefile or something to run
on 2 processors? In master it looks like
runex52_superlu:
-@${MPIEXEC} -n 1 ./ex52 -use_superlu_ilu > ex52.tmp 2>&1;
If you want to run on two processors you need to use superlu_dist
