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