Take a look at the 64 bit AMD Opteron benchmarks results at
http://www.polyhedron.com/ and google comp.lang.fortran.
It seemed to be able to run all the benchmarks correctly.

The Polyhedron benchmarks showed the Intel compiler coming in
just behind the Pathscale compiler in 64 bit mode on an Opteron.
The benchmarks don't use OpenMP though.
