The cluster manager works together with a cluster management agent. These agents run on each node of the cluster to manage and configure services, a set of services, or to manage and configure the complete cluster server itself (see supercomputing.) In some cases the cluster manager is mostly used to dispatch work for the cluster (or cloud) to ...

A computer cluster may be a simple two-node system which just connects two personal computers, or may be a very fast supercomputer. A basic approach to building a cluster is that of a Beowulf cluster which may be built with a few personal computers to produce a cost-effective alternative to traditional high-performance computing.
The following tables compare general and technical information for notable computer cluster software. This software can be grossly separated in four categories: Job scheduler, nodes management, nodes installation and integrated stack (all the above).
The Slurm Workload Manager, formerly known as Simple Linux Utility for Resource Management (SLURM), or simply Slurm, is a free and open-source job scheduler for Linux and Unix-like kernels, used by many of the world's supercomputers and computer clusters. It provides three key functions:
In Kubernetes, all objects serve as the "record of intent" of the cluster's state, and are able to define the desired state that the writer of the object wishes for the cluster to be in. [73] As such, most Kubernetes objects have the same set of nested fields, as follows:
Borg is a cluster manager used by Google since 2008 or earlier. [1] [2] It led to widespread use of similar approaches, such as Docker and Kubernetes. [3] See also.
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 ...
