A computer cluster is a group of autonomous computers that work together so that they can be viewed as a single system. Unlike grid computers, computer clusters have each node set to perform the same task, controlled and scheduled by software. The newest manifestation of cluster computing is cloud computing.
The components of a cluster are usually connected to each other through fast local area networks, with each node (computer used as a server) running its own instance of an operating system. In most circumstances, all of the nodes use the same hardware and the same operating system, although in some setups (e.g. using Open Source Cluster Application Resources (OSCAR)), different operating systems can be used on each computer, or different hardware.
Clusters are usually deployed to improve performance and availability over that of a single computer, while typically being much more cost-effective than single computers of comparable speed or availability.
Computer clusters emerged as a result of the convergence of a number of computing trends including the availability of low-cost microprocessors, high-speed networks, and software for high-performance distributed computing. They have a wide range of applicability and deployment, ranging from small business clusters with a handful of nodes to some of the fastest supercomputers in the world such as IBM's Sequoia. Prior to the advent of clusters, single-unit fault tolerant mainframes with modular redundancy were employed; but the lower upfront cost of clusters, and increased speed of network fabric has favoured the adoption of clusters. In contrast to high-reliability mainframes, clusters are cheaper to scale out, but also have increased complexity in error handling, as in clusters error modes are not opaque to running programs.

X.AI LLC, doing business as xAI, is a subsidiary of the American spaceflight company SpaceX working in the areas of artificial intelligence (AI) and social media. xAI's flagship products are the generative AI chatbot Grok and the social network X, which was acquired in March 2025. It has also constructed the Colossus supercomputer and launched a data center business. The company was going to develop a humanoid AI platform called Macrohard, which was intended for integration into a future robotic workforce across a range of applications; its current focus is developing virtual assistants. Prior to being acquired by SpaceX in February 2026, xAI's assets were part of a standalone corporation named X.AI Corp., founded by Elon Musk and 11 researchers in 2023.
