Compiler for 64-bit Xeon?

Compiler for 64-bit Xeon?

I've been given access to a 64-bit Xeon to run a few test benchmarks. I'm looking for an intel compiler that fully supports the isa to ensure I get a reasonable comparison, but I can't seem to find one. The 8.0 Linux C++ compiler seems to offer IA-32 and Itanium - doesn't seem to be any non-Itanium 64-bit flags in the User Guide that I can see. uname -a on my host reports:

Linux [hostname] 2.6.5-1.358smp #1 SMP Sat May 8 09:28:14 EDT 2004 x86_64 x86_64 x86_64 GNU/Linux

So I guess I'm looking for x86_64 support?
