Chapter 1. Cluster Architecture
Computing speed isn't just a convenience. Faster
computers allow us to solve larger problems, and to find solutions
more quickly, with greater accuracy, and at a lower cost. All this
adds up to a competitive advantage. In the sciences, this may mean
the difference between being the first to publish and not publishing.
In industry, it may determine who's first to the
patent office.Traditional high-performance
clusters have
proved their worth in a variety of usesfrom predicting the
weather to industrial design, from molecular dynamics to astronomical
modeling. High-performance computing
(HPC) has created a new approach to sciencemodeling
is now a viable and respected alternative to the more traditional
experiential and theoretical approaches.Clusters are also playing a greater role in business. High
performance is a key issue in data mining or in image rendering.
Advances in clustering technology have led to high-availability and
load-balancing clusters. Clustering is now used for mission-critical
applications such as web and FTP servers. For example, Google uses an
ever-growing cluster composed of tens of thousands of computers. |
