Top500 ranking is based on the performance of "HPL" or the "High-Performance
Linpack Benchmark for Distributed-Memory Computers".  It's a non-trivial
activity to get the number, as you need to understand what the benchmark is
doing and how to tune it for your system.  You also need an increasingly
faster (lower latency and higher bandwidth) network as cluster size increases.

The minimum entry has exceeded 1 TF in the last four lists (i.e., since ISC
2005)--the current #500 is almost three times faster at 2736 GF; the current
#1 is two orders of magnitude larger at 280.6 TF.

At any rate, take a look at Top500 itself <http://www.top500.org/> and
especially the "About" page if you want to understand more or give it a go.
