The process is to be fully mechanistic so that, with no human resequencing required or permitted, a \"numerical procedure debugging\" tool is made available. Other goals include a quantification of the order-of-precision decision for specified accuracy, provision of an observational tool for determining word length requirements, and an automatic facility for utilizing other kinds of arithmetic interpretively in executing existing programs and program segments. The experimental package consists, in effect, of a compiler from FORTRAN source language into an artificial machine language in which arithmetic operations produce, in addition to numerical results, a measure of the current accuracy of each result operand.","PeriodicalId":148361,"journal":{"name":"Symposium on Interactive Systems for Experimental Applied Mathematics","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1967-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127855509","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Numerous papers have presented evaluation models based upon queuing theory [3,4]. This paper presents an alternative model which is quite general since it is independent of the microscopic properties of any given interactive system. By supplying to the model from four to seven experimentally determined parameters for a given interactive system, we can compute a numerical throughput optimization factor, and also a demand optimization factor in the case of time-dependent demands from the terminals. Additionally, for systems meeting a small number of restrictions, the model predicts quantitative relationships between the throughput and the implementation of techniques such as that of dynamically varying the scheduling algorithm.","PeriodicalId":148361,"journal":{"name":"Symposium on Interactive Systems for Experimental Applied Mathematics","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1967-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128969040","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the area of scientific applications, such a language approach permits faster total throughput, i.e., less time spent in programming or debugging a specific problem compared to conventional FORTRAN-like languages. It also offers a basic framework for extension into other areas such as the manipulation and editing of two-dimensional mathematical input for automatic typesetting of mathematical text [4]. A typical program segment in this language is illustrated in Fig. 1. More visually complex forms, such as multiple integrals, sums, products, and \"IF\" conditions are also recognized and compiled.","PeriodicalId":148361,"journal":{"name":"Symposium on Interactive Systems for Experimental Applied Mathematics","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1967-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125638963","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
