UNICOS

<p>UNICOS is a range of <a href="/facts/Unix/0pNL2seI">Unix</a> and later <a href="/facts/Linux/9FvCKSTq">Linux</a> <a href="/facts/Operating_system/8XTuvMh2">operating system</a> (OS) variants developed by <a href="/facts/Cray/coAlupuy">Cray</a> for its <a href="/facts/Supercomputer/HT9NwGAN">supercomputers</a>. UNICOS is the successor of the <a href="/facts/Cray_Operating_System/6n4t0yR2">Cray Operating System</a> (COS). It provides network <a href="/facts/Cluster_(computing)/mT7S1BcX">clustering</a> and source code <a href="/facts/Compatibility_layer/UU3le7BV">compatibility layers</a> for some other Unixes. UNICOS was originally introduced in 1985 with the <a href="/facts/Cray-2/bljhxYCT">Cray-2</a> system and later ported to other Cray models. The original UNICOS was based on <a href="/facts/UNIX_System_V/Epm6GEY4">UNIX System V</a> Release 2, and had many <a href="/facts/Berkeley_Software_Distribution/XQKcURrh">Berkeley Software Distribution</a> (BSD) features (e.g., <a href="/facts/Computer_networking/3w5RM99p">computer networking</a> and <a href="/facts/File_system/FdPm90uc">file system</a> enhancements) added to it.
