You can find where the printout by doing a grep on "EIGENVALES B" but I
would be surprised if this is useful.

The next thing I would do is check that the same compilers were used for
everything and run one of the scalapack test codes (i expect there are
some). I personally have no idea what might be wrong, I am just trying to
eliminate possibilities.

If you turn on debugging in lapw1para you can work out the individual
mpirun command and run it at the terminal. Sometimes this shows up hidden
errors.
