'''UNICOS''' is a range of [[Unix]] and later [[Linux]] [[operating system]] (OS) variants developed by [[Cray]] for its [[supercomputer]]s. UNICOS is the successor of the [[Cray Operating System]] (COS). It provides network [[Cluster (computing)|clustering]] and source code [[compatibility layer]]s for some other Unixes. UNICOS was originally introduced in 1985 with the [[Cray-2]] system and later ported to other Cray models. The original UNICOS was based on [[UNIX System V]] Release 2, and had many [[Berkeley Software Distribution]] (BSD) features (e.g., [[computer networking]] and [[file system]] enhancements) added to it.
