The correct program is synthesized even though certain indexing instructions are omitted by the user as he executes the sample calculation. The created program can be tested, debugged, and modified by running examples at the display terminal, observing the program behavior, and forcing by hand a change in behavior if errors are observed. Thus programs can be created, debugged, and modified without the user ever knowing or seeing any traditional language syntax. Most of the methods discussed have been programmed and tested extensively.","PeriodicalId":447373,"journal":{"name":"ACM '75","volume":"58 24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125619243","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}

This development has already begun to influence computer system architecture in the direction of distributed processing—the construction of a larger machine from a multiplicity of smaller ones. Critical issues in this effort appear to be process partitioning and assignment, interprocess communication, and processor interconnection. In a distributed computer, processors may function as: special purpose components (e.g., decimal processing unit) in a larger processor; dedicated support (e.g., I/O) processors; or multiple main (i.e., “central”) processors.","PeriodicalId":447373,"journal":{"name":"ACM '75","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123557393","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}

Some techniques to generally improve software quality are reasonably well know—structured walk-throughs, precise statement of requirements, and use of appropriate programming languages. Experience with developing large scale software, however, has indicated that additional techniques are required. This session will deal with some techniques used by developers of large-scale software to achieve quality, and to provide assurance of the product's quality. These techniques are design validation (prior to implementation), configuration management (during implementation), and software validation (of implemented software).","PeriodicalId":447373,"journal":{"name":"ACM '75","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117010462","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 obvious definition of a STAND ALONE SYSTEM has likewise remained unchanged; computers, however, have not. The last 10 years have seen a dramatic change in both the cost and the performance of small machines. We believe these changes strongly favor the development of stand alone systems now and in the future.\u0000 Examination of the problem at hand shows a spectrum of computer tasks with a range of acceptable response times. The tasks require different degrees of machine performance with certain, but not all, tasks requiring high performance equipment. This is perhaps the major dillemma encountered in designing these systems.","PeriodicalId":447373,"journal":{"name":"ACM '75","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129877505","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 principal objective of this approach is the development of languages that are easy to use; it is argued that conventional language designs do not satisfactorily achieve this goal. The basic principles of the proposed approach are restriction and discipline: by appropriately limiting the programmer's freedom of choice, the number of decisions he must make can be reduced. In particular, it is argued that languages should be designed for individual problem areas, and that each language should be built around a style of problem solving, an algorithmic structure appropriate to its application domain. Principles of declarative and data-oriented programming, which avoid a processor-oriented view of computation, are also set forth.","PeriodicalId":447373,"journal":{"name":"ACM '75","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125149373","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}
