Cluster Computing

Abstract

A computer cluster is a collection of loosely linked computers that operate together so closely that they appear to be one computer in many ways. Clusters are frequently connected via fast local area networks. Clusters are frequently used to increase the performance and/or dependability of a single computer while also being significantly less expensive than single machines of equivalent speed and reliability. Cluster computing arose from the convergence of numerous developments, including the affordable availability of high- performance microprocessors and high-speed networks, as well as the creation of standard software tools for high-performance distributed calculate. Clusters have grown to accommodate a wide range of applications, including ecommerce and high-performance database applications. The fundamental goal of a cluster computer is to perform a task in a shorter amount of time by employing processing node groups. This is accomplished by moving loads from busy to idle nodes. Transferring excess loads from active nodes to idle nodes is one approach for achieving this goal.
