Sun Enterprise M9000: 1032 Giga floating point operations per second
The Sun SPARC Enterprise M900 with 64 processors was benchmarked recently with over 1 TFLOPS. This is a little bit more than a thirth of the the 500th fastest compute site in the world. But in the case of the M9000, it´s a single system with a single operating system image. Thus you can compute task that lies outside the specialized task of this clusters with a massive amount of nodes. For example computations with heavy dependencies between the calculations. Communication between processors in a SMP system is faster than communication via Infiniband or Ethernet.
