Clusters figure highly in top supercomputer list

While the overall rate of performance growth of the top 500 systems is steady, distributed clusters of generally off-the-shelf microprocessors are taking larger shares of these high-end systems. Indeed, seven of the top 10 systems are now clusters. The exceptions are NEC Corp.’s Earth Simulator, by far the most powerful system in the world at 35.8 Tflops and two IBM SP-class proprietary systems ranked 8th and 9th.
