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

Would MSC use a beta compiler for such a project ?

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 ....
