Operating Systems I | Intro, History PT/FF 2014

The First Computer(s)

• 1801: Power loom driven by wooden punch cards

• 1822: Steam-driven analytical engine by Charles Babbage

• Mechanical decimal stored-program computer, programmable by punch cards, support for calculation and conditional statements

• Remained unbuilt; Ada Byron invented anyway subroutine and looping as programming concepts

• 1890: U.S. census supported by Hollerith desk - punch card reader, counting units, wall of dial indicators

• Built by Tabulating Machine Company, which eventually became International Business Machines

• Invented the idea of output punch cards independent from Babbage

The First Computer(s)• 1944: Harvard Mark I developed in partnership between

Harvard and IBM (ballistic firing tables)

• First programmable digital computer made in the U.S.

• Constructed of switches, relays, rotating shafts, clutches

• Grace Hopper found the first computer bug, invented the precessor of COBOL and the first compiler

• 1941: Konrad Zuse completed the work on the Z3

• First programmable electromechanical computer

• Punch film for program and data (lack of paper)

• Mapping of Boolean algebra to relays, developed independently from original Shannon work

Von Neumann Architecture

�4

(C) Wikipedia

• 1946: ENIAC as first fully electronic computer in the U.S.

• No program memory, re-wiring for each program

• EDVAC: Revolutionary extension with a stored program computer concept by John von Neumann

• Memory contains both the program and the data

• Introduction of a general purpose computer concept


Serial Processing

• Computers from 1940 to 1955 were able to perform serial processing

• Programs for the machine (relays, vacuum tubes) written in assembly language

• Console with display lights, switches, punch card reader / plugboard, printer

• Re-wiring or punch card reading necessary for filling the program memory

• Program had complete control of the machinefor the entire run-time

• Manual reservation, user either finished early(wasted time) or couldn‘t debug their problem

• Long setup time -Job may involve running the compilerprogram first and feeding in the output again

�5


Batch Processing• IBM 1401 - October 5th, 1959

• IBM‘s first affordable general purpose computer, i.e. for accounting

• 1401 Processing Unit, 1402 Card Read-Punch (250 cards/minute), printer

• First concepts of batch processing for multiple job input cards

• Operator loads monitorto run batched jobs from a prepared input tape

• Programs are constructed to branch back to the monitor after termination(early Fortran language)

• First version of a scheduler, better utilization of the extremely expensive hardware�6

1.b Operating System History and FeaturesSimple batch systems

a) programmer brings cards to IBM 1401b) 1401 reads batch of jobs onto tapec) operator carries input tape to IBM 7094d) 7094 does computinge) operator carries output tape to 1401f) 1401 prints output

Tanenbaum, A. S. (2001)Modern Operating Systems (2nd Edition).

An early IBM batch system


Batch Processing

• A job control language (JCL) operates the monitor application

• Instructions about the compiler to use, data to work on etc. (Fortran prefix $)

• Early version of system calls

• Monitor needed to switch between itself and the application

• Resident monitor parts always in memory

• Demands on hardware: memory protection, timer, privileged instructions for I/O

• User mode vs. monitor mode (,system mode‘, ,kernel mode‘, ,supervisor mode‘)

�7

(C) Stallings


Multi-Programming

• Batch processing is nice, but jobs still spend too much time on I/O completion

• Idea: Load two jobs into memory at the same time

• While one is waiting for I/O results, switch to the other one

• Multiplexing of resources between a set of jobs became a basic monitor / operating system task -> multi-programming or multi-tasking

• Goal: Maximize CPU utilization by sacrificing memory

1.b Operating System History and FeaturesMultiprogrammed batch systems

¾ Solution?¾ Solution: load two jobs in memory9 while one job is waiting for I/O, the processor could switch to

the other job

Time Sharing

• Users started to demand interaction with their program, e.g. for retry on errors

• Perform multi-tasking, but act like the machine is solely used

• Advent of time-sharing / preemptive multi-tasking systems

• Goal: Minimize single user response time

• Extension of multi-programming to multiple interactive (non-batch) jobs

• Starting point for Unix operating systems in the 1960‘s

• Preemptive multi-tasking became a single user demand in modern times

• Leave application running while starting another one

• Pure batch processing systems are still significant (TPM, SAP R/3, HPC)

�11


Time-Sharing• Compatible Time-Sharing System (CTSS)

• Operating system developed at MIT, first for the IBM 7094 in 1961 (32.768 36bit words memory)

• Program always loaded to start at the location of the 5000th word

• System clock generated interrupts roughly every 0.2 seconds

• At each clock interrupt, the system regained control and assigned the processor to another user - time slicing

• Parts of the active program that would be overwritten are written to disk

• Other parts remained inactive in the system memory

• Direct successor MULTICS pioneered many modern operating system concepts�12

Note 1 : an arrow indicates an inheritance like a compatibility, it is not only a matter of source code.

Note 2 : this diagram shows complete systems and [micro]kernels like Mach, Linux, the Hurd... This is because sometimes kernel versions are more appropriate to see the evolution of the system.

Note 1 : an arrow indicates an inheritance like a compatibility, it is not only a matter of source code.

Note 2 : this diagram shows complete systems and [micro]kernels like Mach, Linux, the Hurd... This is because sometimes kernel versions are more appropriate to see the evolution of the system.

History of Windows [Lucovsky]

• Initial team formed in November 1988

• 6 former Digital developers, one Microsoft guy

• Focus on secure, scalable SMP design for desktops and servers

• Original schedule for 18 months, missed by 3 years

• Goal setting

• Portability: Initial focus on Intel i860, intentionally late focus on i386

• Reliability: Nothing should be able to crash the OS (promise fulfilled)

• Extensibility and compatibility (DOS, OS/2, POSIX)

• After all of the above - performance

• NT 3.1 had 6-200 developers, NT 4.0 800 developers, Windows 2000 had 1400

�19


Windows and Linux Evolution

• Windows and Linux kernels are based on foundations developed in the mid-1970s
