It provides fast response and efficient execution to a large number of typewriter terminals. With 40 to 50 terminals connected and in normal use, each with a block of storage (called a workspace) allocated, reaction time (defined as the time from completion of an input message until the user's program begins execution) is typically 0.2 to 0.5 second. At the terminal this is manifested by nearly instantaneous response to a trivial request. Under these conditions, the CPU is executing user programs about 75% of the time, while supervisor overhead and I/O waiting time amount to less than 5%. The APL processor is interpretive; however, because of the efficiencies afforded by array operations, program execution is often one-tenth to one-fifth as fast as compiled code. APL360 is currently running on a System/360 Model 50 with 262,144 bytes of core storage, a 2314 Direct Access Storage Facility, and two 2702 Transmission Control Units to which IBM 1050 and 2741 Communication Terminals are connected via telephone lines.","PeriodicalId":148361,"journal":{"name":"Symposium on Interactive Systems for Experimental Applied Mathematics","volume":"50 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":"121137500","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}

The polyalgorithms depend essentially on their objectives which are presented and discussed in the next section. The objectives of the NAPSS polyalgorithms are quite high and the four primary difficulties (met so far) in achieving them are discussed in the third section. These four difficulties are common sense, error control, flexibility versus simplicity, and reliability versus efficiency. Some of the approaches used in NAPSS to overcome these difficulties are given.","PeriodicalId":148361,"journal":{"name":"Symposium on Interactive Systems for Experimental Applied Mathematics","volume":"397 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":"122856214","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}

The capabilities made available in systems supporting these laboratories range from symbolic integration, differentiation, and polynomial and power series manipulation, through mathematical simulation, to direct control experimental systems. About 1961 two trends, one toward what has become known as \"on-line\" computation, the other toward \"time-sharing\" had gained enough recognition to develop national support, and subsequently they have come to represent what is now known as modern computation. An on-line system provides interactive facilities by which a user can exert deterministic influence over the computation sequence; a time-sharing system provides a means by which partial computations on several different problems may be interleaved in time and may share facilities according to predetermined sharing algorithms. For reasons of economy it is hard to put a single user in direct personal control (on-line, that is) of a large-scale computer. It is equally (or even more) difficult to get adequate computation power for significant scientific applications out of any small-scale economical computer. Consequently, on-line computing has come to depend upon time-sharing as its justifiable mode of implementation. On the other hand, valuable on-line applications have formed one of the major reasons for pushing forward the development of time-sharing systems. At present, both efforts have reached such a stage of fruition that we find many systems incorporating selective aspects of the early experimental systems of both types.","PeriodicalId":148361,"journal":{"name":"Symposium on Interactive Systems for Experimental Applied Mathematics","volume":"47 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":"133988660","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}

Discrimination is explicit in the models analyzed by Kesten and Runnenburg [1] and Miller and Schrage [2] in which the priority rule is shortest-job-first. However, in the models of particular interest in this paper, the discrimination is necessarily implicit since it is assumed that the running-times of arriving programs are not known in advance. We shall now describe in detail the queuing models to be analyzed in the following sections. Our initial description will use conventional queuing terminology; subsequently, the correspondences between this terminology and the terminology of our particular application will be established.","PeriodicalId":148361,"journal":{"name":"Symposium on Interactive Systems for Experimental Applied Mathematics","volume":"98 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":"124860064","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}

To illustrate some of these, I shall refer to Professor Glen Culler's on-line system [1, 3], which has been in operation at the University of California at Santa Barbara since 1966. While it is far from an ideal system, I believe that it still ranks first in terms of the number of real problems (of at least moderate difficulty) which have actually been solved, by a variety of users, with the aid of this system or one of its earlier versions. Its strengths and weaknesses have, therefore, some general relevance to a discussion of on-line systems for experimental applied mathematics.","PeriodicalId":148361,"journal":{"name":"Symposium on Interactive Systems for Experimental Applied Mathematics","volume":"6 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":"121809922","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}

The difficulty arises for two reasons. First, because interactive terminals are relatively new, programmers are not accustomed to planning and developing computer dialogs. Second, there is often no easy way to program the dialog once it has been developed. The solution to the first problem is heavily dependent on the programmer, his training and his background, and does not lend itself to a computerized solution. The solution to the second problem, however, can be eased by providing a higher-level, dialog construction language. The basic features for such a language appear in several systems used for computer-aided instruction [1--4]. The Message System builds on these features to provide a dialog construction language for general use.","PeriodicalId":148361,"journal":{"name":"Symposium on Interactive Systems for Experimental Applied Mathematics","volume":"48 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1967-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131588962","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}

Such problems may range from the evaluation of analytical solutions to complicated differential or integral equations on the one hand, to the calculation of coefficients in a power series expansion or the computation of the derivative of a complicated function on the other. The difference between these two classes of problems is obvious; in the former case, no straightforward algorithm exists which will guarantee a solution, and indeed, an analytic form for the solution may not even exist. On the other hand, algorithms do exist for the solution of problems such as series expansion and differentiation, and therefore a correct answer may always be found provided that the researcher possesses sufficient time, perseverance, and accuracy to carry the more complicated problems through free of error. Many examples of this type of problem may be found in physics and engineering. Calculations of general relativistic effects in planetary motion, structural design calculations, and many of the calculations associated with elementary particle physics experiments at high energy accelerators, to name a few, may demand many man-months or even years of work before a useful and error free answer can be found, even though the operations involved are quite straightforward.","PeriodicalId":148361,"journal":{"name":"Symposium on Interactive Systems for Experimental Applied Mathematics","volume":"29 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":"121187535","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}
