    Hi all,
I am trying to compile a little f90 program with LAM/MPI and I get these errors (ERROR 1).
Note that the function have an _ (underscore) character at the end. So I add -nus option to ifort
and i get the same kind of errors (ERROR 2).


Any idea how i can compile my little code?

If you haven't rebuilt lam from source, using the compilers
of your 
choice, do so.  I don't know any place where you could get
a pre-built 
ifort compatible lam.  If you have a g77 built version of
lam, it will 
expect double appended underscores.  A gfortran lam might
work with 
ifort, as both compilers use single appended underscores by
default.
