In addition to the usual benchmarks like SPECfp and Polyhedron, there
is a computational chemistry comparison done by Daresbury Labs in the
UK. Opteron+PathScale does quite well.
We're looking forward to Daresbury testing with our newest compilers,
as we've made some substantial performance improvements since the
version they used (1.2).
