<p>Amenable to extensive parallelization, Google?s web searchapplication lets different queries run on different processors and,by partitioning the overall index, also lets a single query usemultiple processors. To handle this workload, Google's architecture features clusters of more than 15,000 commodity-class pcs with fault-tolerant software. This architecture achievessuperior performance at a fraction of the cost of a system builtfrom fewer, but more expensive, high-end servers.</p>
