Well, I won't go that ... far. That tends to imply that a user knows a lot about a machine. I've been looking at huge code restructuring lately. GO should be something you are at least aware of and be prepared to compare states. Try to run with optimization turned off for instance. This was something we discussed at a Bay Area ACM/SIGGRAPH performance meeting today. Present both numbers. My concept right now is for virtual MachoIPS and MachoFLOPs versus real MachoFLOPS and MachoIPS with the ratio as a comparison of optimization quality. Note: I might not thing this next week.
