Hmm, yes, but as far as I can see the Intel Linux compilers are only in
public field test (beta) at the moment.  See

http://developer.intel.com/software/products/compilers/linux/invitebeta.htm

Would MSC use a beta compiler for such a project ?

[ They aren't very "open" about which compilers they use anyway -
  but they do ship gcc/g77-2.95.2 with their version of Linux ]

Oops, I probably got confused by their press release, which talked about
NASTRAN and CFD, but indeed, not in the same paragraph :-)

Well, the press release doesn't say anything about the number of CPU's
in the cluster, so we can only guess ....
