>>>Dear Prof. Alex.

>>>Thank you for your explanation.

>>>I installed MPICH2 (http://www.mpich.org/http://www.mpich.org/http://www.mpich.org/http://www.mpich.org/ ; mpich2-1.5rc3).

>>>Now, I issued the following command:

>>>mpirun -np 2 firefly8.mpich2.ex -i EXAM09.INP -ex /home/ancborin/ff8_rc40_linux -o exam09.out -f

>>>The new problem: firefly8.mpich2.ex: error while loading shared libraries: libmpich.so: cannot open shared object file: No such file or directory

>>>I thought libmpich.so would be installed during the installation of mpich. I also set library path to LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/ancborin/mpich2-install/lib

>>>I know this this has nothing to do with firefly; but I would appreaciate any help, if possible.

>>>Best,
>>>Antonio
