UNICOS is a range of Unix and later Linux operating system (OS) variants developed by Cray for its supercomputers . UNICOS is the successor of the Cray Operating System (COS). It provides network clustering and source code compatibility layers 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.

41-518: CX-OS was the original name given to what is now UNICOS. This was a prototype system which ran on a Cray X-MP in 1984 before the Cray-2 port. It was used to demonstrate the feasibility of using Unix on a supercomputer system, before Cray-2 hardware was available. The operating system revamp was part of a larger movement inside Cray Research to modernize their corporate software: including rewriting their most important Fortran compiler (cft to cft77) in

82-461: A completely new design, was introduced in 1985. A very different compact four-processor design with from 64 MW (megaword) to 512 MW (512 MB to 4 GB) of main memory, it was specified to 500 MFLOPS but was slower than the X-MP on certain calculations due to its high memory latency. The Cray Y-MP upgrade of the X-MP series was announced in 1988; it also had a new design, replacing

123-795: A guest operating system facility. UNICOS became the main OS from 1986 onwards. The DOE ran the Cray Time Sharing System OS instead. See the Software section for the Cray-1 for a more detailed elaboration of software (language compiler, assembler, operating systems, and applications) as X-MPs and Cray-1s were mostly compatible. Cray Research announced the X-MP Extended Architecture series in 1986. The EA series CPU had an 8.5 ns clock cycle (117 MHz), and

164-457: A guest facility within UNICOS, allowing the stand-alone version of the OS to host itself.
