I get confused with the environment modules with MPICH2 package. It has two identical modules files: /etc/modulefiles/mpich2-i386 /etc/modulefiles/mpi/mpich2-i386 If they are identical, why not to make one of them a symlink? Does even both files needed? For example, in openmpi there is only one file: /etc/modulefiles/mpi/openmpi-i386 -- Andrew Prokhorenkov -- packaging mailing list packaging@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/packaging
