David, can I make SSE4.1 the default in linux_ia64_ifort+mpi_ice_nas
with a comment that 4.2 and 4.3 is also available on some of the newer processors.

4.1 is the lowest common denominator.  That way new pleiades users,
e.g., Pierre Rampal, don't end up with cryptic error messages when
they try to use the default optfile.

Also, according to Art Lazanoff, there is probably not much speed
up to be expected from 4.2 and 4.3 over 4.1.

Let me know, Dimitris
