GPSS was developed by IBM's Geoffrey Gordon at the beginning of the s. He named it Gordon's Programmable Simulation name was changed when IBM decided to release it as a product. The "General Purpose" part of the new name was to create a .

programming. The computer was an IBM System/ mainframe, a Mo I believe. That fall I learned how to write FORTRAN, and snuck my science project into the card hopper whenever there was some idle time. Thus began my lifelong career in the computer industry. I have never worked for IBM as an employee, but was involved with the.

The Lehigh University IBM Simulator (LUIS) is an interactive program which enables a user to execute an IBM machine language program on a Control Data Computer System. LUIS simulates all but seven of the instructions in the IBM System/ standard instruction set. The simulator provides a simulated ten thousand byte.   This thesis describes the simulation of the IBM SYSTEM/7. The research leading to this thesis involved the development of a PL/I computer program that runs on an IBM /50 computer and simulates the IBM SYSTEM/7. Various methods of simulation are examined and guidelines for computer simulation of another computer are established. The SYSTEM/7 simulator (SIM/7) is the Author: Ted C. Lewis.

A simulation model of the IBM computer in an MVT environment. By Allen Kent Varnell Get PDF (2 MB)Author: Allen Kent Varnell. In IBM Corporation announced a new family of room-sized computers, the IBM System.

It included several models of differing cost and capabilities. These embraced a full circle of computer applications, from business data processing to sophisticated science and engineering; hence the name To sell the new product, IBM salesmen used scale models like this one.

Jim Collins, author of Good to Great, ranks the S/ as one of the all-time top three business accomplishments, along with Ford’s Model T and Boeing’s first jetliner, the It set IBM on a path to dominate the computer industry for the following 20 years.

Our installation includes an IBM / and an IBM / coupled in an Asymmetric Multiprocessing System (ASP) with sixty or so I/O devices. When we decided to model the system, we felt that conventional simulation detail would make desired. A brief description of the simulation models is given and some results of the simulation are presented.

Comm. 7 (July ), The simulation of the IBM /67 timesharing system is described in this by: In this paper we present some results obtained from using simulation as a tool for evaluating alternative methods of improving system performance in network computers.

We begin by describing a GPSS model which was developed to evaluate the current computer center operations at the University of Illinois.

The IBM was introduced in with six models and a perfor-mance ratio. Amdahl, Blaauw, and Brooks [] discuss the architecture of the IBM and the concept of permitting multiple object-code–compatible imple-mentations. The notion of an instruction set architecture as we understand it today was the most important aspect of the File Size: 71KB.

Input data collection and analysis, model construction, project mechanics, output analysis, verification, validation, reporting, logic transfer, and robust experimental design are all covered in detail/5(32).

This paper explains the multiprocessing-via-the- terminal approach to interactive simulation taken at the Applied Physics Laboratory. Two systems are discussed: (a) the simulation console (SIMCON) used for all-digital interactive computing, and (b) the hybrid computer used for analog/digital : P.F.

Bohn. Within IBM, model 67 was used with a systemknown as CP, which allowed a single /67 to simulate multiplemachines of various models. This turned out to be very usefulfor developing operating systems.
