Title: Supercomputer operating system
Content:  The CDC 6600, generally considered the first supercomputer in the world, ran the Chippewa Operating System, which was then deployed on various other CDC 6000 series computers. The Chippewa was a rather simple job control oriented system derived from the earlier CDC 3000, but it influenced the later KRONOS and SCOPE systems. The first Cray-1 was delivered to the Los Alamos Lab with no operating system, or any other software. Los Alamos developed the application software for it, and the operating system. The main timesharing system for the Cray 1, the Cray Time Sharing System (CTSS), was then developed at the Livermore 
Title: Linux
Content:   The Unix operating system was conceived and implemented in 1969, at AT&T's Bell Labs, in the United States by Ken Thompson, Dennis Ritchie, Douglas McIlroy, and Joe Ossanna. First released in 1971, Unix was written entirely in assembly language, as was common practice at the time. In 1973 in a key, pioneering approach, it was rewritten in the C programming language by Dennis Ritchie (with the exception of some hardware and I/O routines). The availability of a high-level language implementation of Unix made its porting to different computer platforms easier. Due to an earlier antitrust case forbidding it from entering the computer business, AT&T was required to license the operating system's source code to anyone who asked. As a result, Unix grew quickly 
Title: Burroughs MCP
Content:  The MCP was the first OS developed exclusively in a high-level language. Over its 50-year history, it has had many firsts in a commercial implementation, including virtual memory, symmetric multiprocessing, and a high-level job control language (WFL). It has long had many facilities that are only now appearing in other widespread operating systems, and together with the Burroughs large systems architecture, the MCP provides a very secure, high performance, multitasking and transaction processing environment.

Content:  Labs. On the PDP-7, in 1969, a team of Bell Labs researchers led by Thompson and Ritchie, including Rudd Canaday, implemented a hierarchical file system, the concepts of computer processes and device files, a command-line interpreter, and some small utility programs, modeled on the corresponding features in Multics, but simplified. The resulting system, much smaller and simpler than Multics, was to become Unix. In about a month's time, in August 1969, Thompson had implemented a self-hosting operating system with an assembler, editor and shell, using a GECOS machine for bootstrapping. Douglas McIlroy then ported TMG compiler-compiler to PDP-7 assembly, creating the first high-level language running on Unix. Thompson used this tool to develop the first version of his B programming language.

Title: History of programming languages
Content:  by Douglas Hartree of University of Cambridge Mathematical Laboratory in 1961. Known as EDSAC 2 Autocode, it was a straight development from Mercury Autocode adapted for local circumstances and was noted for its object code optimization and source-language diagnostics which were advanced for the time. A contemporary but separate thread of development, Atlas Autocode was developed for the University of Manchester Atlas 1 machine. In 1954, FORTRAN was invented at IBM by a team led by John Backus; it was the first widely used high-level general purpose programming language to have a functional implementation, as opposed to just a design on paper. When FORTRAN was first introduced, it was viewed with skepticism due

The B5000 was also unique, for its time, in that its operating system and core utilities were all programmed in a high-level language, ESPOL. ESPOL was a derivative of the ALGOL language tuned to work on the B5000's, a concept that was highly influential in the 1960s and led to new languages like JOVIAL, PL/360 and BCPL. The HP team decided they would also use an ALGOL-derived language for their operating systems work. HP's similar language was initially known 
Title: Computer programming
Content:  High-level languages made the process of developing a program simpler and more understandable, and less bound to the underlying hardware. The first compiler related tool, the A-0 System, was developed in 1952 by Grace Hopper, who also coined the term 'compiler'. FORTRAN, the first widely used high-level language to have a functional implementation, came out in 1957, and many other languages were soon developed—in particular, COBOL aimed at commercial data processing, and Lisp for computer research. These compiled languages allow the programmer to write programs in terms that are syntactically richer, and more capable of abstracting the code, making it easy to target for varying machine instruction sets via compilation declarations and heuristics. Compilers harnessed the power of computers to make programming easier by allowing programmers to specify calculations by entering a formula using infix notation.
Title: Burroughs MCP
Content:  In 1961, the MCP was the first OS written exclusively in a high-level language (HLL). The Burroughs Large System (B5000 and successors) were unique in that they were designed with the expectation that all software, including system software, would be written in an HLL rather than in assembly language, which was a unique and innovative approach in 1961. Unlike IBM, which faced hardware competition after the departure of Gene Amdahl, Burroughs software was designed to run only on proprietary hardware. For this reason, Burroughs was free to distribute the source code of all software it sold, including the MCP, which was designed with this openness in mind. For example, upgrading 
Title: Supercomputer operating system
Content:  generic software. The first wave in operating system changes came in the mid 1980s, as vendor specific operating systems were abandoned in favor of Unix. Despite early skepticism, this transition proved successful. By the early 1990s, major changes were occurring in supercomputing system software. By this time, the growing use of Unix had begun to change the way system software was viewed. The use of a high level language (C) to implement the operating system, and the reliance on standardized interfaces was in contrast to the assembly language oriented approaches of the past. As hardware vendors adapted Unix to their systems, new and useful features were added to Unix, e.g.,
