The history of early computer clusters is more or less directly tied to the history of early networks, as one of the primary motivations for the development of a network was to link computing resources, creating a de facto computer cluster. The first production system designed as a cluster was the Burroughs B5700 in the mid-1960s. This allowed ...
The cluster system categorizes humanization activities into eleven work areas, and four cross-cutting themes, and identifies coordinating organizations for each of them. [ 3 ] The coordination system has improved some aspects of humanitarian responses, and while it empowers international organizations, it also excludes local and national ...
Cluster analysis or clustering is the task of grouping a set of objects in such a way that objects in the same group (called a cluster) are more similar ...

The most common size for an HA cluster is a two-node cluster, since that is the minimum required to provide redundancy, but many clusters consist of many more, sometimes dozens of nodes. The attached diagram is a good overview of a classic HA cluster, with the caveat that it does not make any mention of quorum/witness functionality (see above).
In 1995 the Beowulf cluster—a cluster built on top of a commodity network for the specific purpose of "being a supercomputer" capable of performing tightly coupled parallel HPC computations—was invented, [3] which spurred the independent development of grid computing as a named entity, although Grid-style clustering had been around at least ...

Beowulf also uses commodity software like the FreeBSD, Linux or Solaris operating system, Parallel Virtual Machine and Message Passing Interface . The server node controls the whole cluster and serves files to the client nodes. It is also the cluster's console and gateway to the outside world. Large Beowulf machines might have more than one ...
