Analysis of Account Dayfiles for the CDC 6400 Computer Under NOSNg, Hok-Nam 09 1900 (has links)
<p> System performance evaluation is an on-going task for computer
system management personnel in order to fine-tune the system operations.
One of the evaluation aids that is readily available for the CDC 6400
computers is the job accounting dayfile maintained by the operating
system NOS. A set of three programs in FORTRAN has been developed
to analyze the dayfile with a view to evaluating the system performance.
Program PHASEl prepares the dayfile for analysis. Program
PHASE2 creates a job summary file with information on system resources
utilization by each job. Program PHASE3 analyzes the job summary
file by evaluating various parameters characterizing the system
workload and performance at regular time intervals. The results
are displayed in tabular and graphical forms. Test results from
the analysis of a limited number of dayfiles are discussed. </p> / Thesis / Master of Science (MSc)

An Appraisal Of The Supernova Minicomputer As A Process Simulation ToolForan, Charles 01 1900 (has links)
<p> The object of this work was to evaluate the Supernova ninicomputer as a process simulation tool. To accomplish this obje c tive the GEMCS ste2dy-state simulation system wa.s programmed for the Supernova. This system was programmed to run in five different modes, BASIC , two modes which require that al.L progra1ns are written in Assembly Language, and two modes in which programs may be called from the disk. Of these latter two modes, one requires all programs to be written in Assembly Language; the other mode allows programs to be written in Assembly Language or FORTRAN IV. </p>
<p> Two case studies which had previously been run on the CDC 6400 were run on the Supernova to test and evaluate f our of the modes in which GEMCS was proerammed for the Supernova. </p>
<p> The studies have also provided an a ssessment of the hardware and softws.re facilities of the Supernova and the results of thjs assessment were documented. In addition the opera tion of the various strategies used to impl ement GEMCS have provided an indication of the feasibility of the impl ementation of the dynamic system simulation program, DYNSYS. </p> / Thesis / Doctor of Philosophy (PhD)
