This paper presents an algebraic characterization of the sets of communication paths that a network can simultaneously establish between the processing elements of the system. This characterization provides a uniform framework for the analysis of interconnection networks and is shown to yield answers to several important questions concerning the capabilities, limitations and operation of these networks. The networks considered include one way and two way shift register rings, near neighbor meshes, single stage switching networks and briefly, multistage switching networks.","PeriodicalId":365511,"journal":{"name":"1984 IEEE First International Conference on Data Engineering","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1984-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131885684","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}

It was designed in a Pascal-like language for a target multimicroprocessor that contains six microcomputer processing elements and twelve shared memories fully interconnected by a crossbar switch. Each processing element in the host multimicroprocessor executes Gaurdian tasks that perform shared memory reclamation, internodal communication, health monitoring, task scheduling, fault containment, and distributed debugging. Each node also supports application-callable software primitives for realtime process control, message-based interprocess communication, shared data structure management, and exception handling. The primary goal of Guardian is to demonstrate hard real-time decentralized control of an embedded multimicroprocessor.","PeriodicalId":365511,"journal":{"name":"1984 IEEE First International Conference on Data Engineering","volume":"140 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1984-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124621304","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}

It assists computer users (novice or experienced), who attempt to use unfamiliar system facilities, by giving prompt advice of a sequence of commands to accomplish a desired user task. The domain for CMS-HELP is the collection of CMS command modules and EXEC's at IBM Research. This set of command facilities is treated as data by the expert system. The source of knowledge is mainly provided by the command descriptions and system consultants, who are expert users of these commands. This expert system exemplifies data/knowledge engineering to develop an intelligent agent capable of providing on-line consultation. Thereby, the system serves important functions to both the developers and the users of CMS commands: it makes the programs more usable and understandable and it makes the users more productive and receptive. Thus, the system brings data/knowledge and its users closer together.","PeriodicalId":365511,"journal":{"name":"1984 IEEE First International Conference on Data Engineering","volume":"178 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1984-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129583868","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 generated fixed-length codes are preserving the order on the original data representations in the sense of semiorder preservation as defined in this paper. The FLSOPC employing binary sectioning assignment algorithm requires the code size that is linear to logarithm of the data cardinality. It is about 2.8 times that required by FLMB (fixed-length minimum bit) encoding when no knowledge about data is given a priori. This factor can be reduced to 2.1 if a half of data has been available as the initial load and approaches 1 when even more data is known.","PeriodicalId":365511,"journal":{"name":"1984 IEEE First International Conference on Data Engineering","volume":"140 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1984-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115127375","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}

As such, they aid users in transforming objects with an initial state vector to some desired outcome state by application of a suitable control policy. System effectiveness can be measured by the number of decision errors. Completeness and validity of the knowledge base can be facilitated by coupling a database of instances of system use with the implementation of the knowledge base. Instances of system use are viewed as traces which should be consistent with the knowledge base. The database contains records characterizing each instance of system use (a trace) and includes the state vector of the object being controlled, the selected control strategy, and the resultant outcome state vector. Stability of control policies is improved within the decision process by incorporating a feedback data path that is derived from actual outcomes resulting from application of a control policy.","PeriodicalId":365511,"journal":{"name":"1984 IEEE First International Conference on Data Engineering","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1984-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115148225","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}
