 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).
