Good luck. Unfortunately, running linpack (top500) is not so straight forward 
- compiling is the easy part. Optimizing it for your setup is time consuming 
and a single run can easily last for hours (at least it did for us).

To get (close) to the optimum you need experience (or a lot of luck).

An easy number to quote is what condor derives from its benchmarking or what 
the theoretical peak performance of your CPUs is.

Sorry for not being very specific but it's really hard to get a good metric.
