The algorithm, called FREA (fast reliability evaluation algorithm), is based on the generalized factoring theorem with several incorporated reliability-preserving reductions to speedup the reliability evaluation. The effect of file distributions, program distributions, and various topologies on reliability of the DCS is studied in detail using the proposed algorithm. Compared with existing algorithms on various network topologies, file distributions, and program distributions, the proposed algorithm is much more economic in both time and space. To compute the distributed program reliability, the ARPA network is studied to illustrate the feasibility of the proposed algorithm.<<ETX>>","PeriodicalId":186762,"journal":{"name":"Proceedings of the Third Workshop on Future Trends of Distributed Computing Systems","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123092275","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 system allows the user to custom build a graphical environment in which a uniform set of commands is provided for all the databases chosen to be members of that environment. The paper also includes preliminary description of a system, currently under development, that provides this integration. The system is designed to satisfy a few principles that guarantee that no degradation of previously existing user skills will occur and that the system can be tailored to the needs of different classes of users. The design goals of the system also include operation and database extensibility and robustness in the sense that only a minimal amount of effort is required to accommodate changes in individual database.<<ETX>>","PeriodicalId":186762,"journal":{"name":"Proceedings of the Third Workshop on Future Trends of Distributed Computing Systems","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122755573","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}

However, both solutions prove to be unsatisfactory. While the former alternative rarely meets application needs, the latter usually yields poor software which is difficult to maintain and re-structure. This approach suggests the use of a simple concurrency model well-suited for expressing both real-time and real parallelism. It is based on a language extension providing features for high-level real-time distributed programming. Such a language extension can be easily embedded in any sequential language (e.g. C, C++ or Modula-2). This allows programmers to develop complex systems using their favourite language extended with a small set of new constructs.<<ETX>>","PeriodicalId":186762,"journal":{"name":"Proceedings of the Third Workshop on Future Trends of Distributed Computing Systems","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128710538","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}

An object can request other objects to do some services by passing messages through a communication system. Usually, the services are done if the message transmission on the communication system is reliable. However, in some applications with timing constraints, a service may be of no value if it violates some constraints. The authors thus can allow the object to send the constraint within the message to avoid this useless service. In validating the satisfaction of a service for a constraint, using the current elapsed time and using the predicted elapsed time are discussed. The relative accuracy of the prediction in several types of message transmissions is also explained.<<ETX>>","PeriodicalId":186762,"journal":{"name":"Proceedings of the Third Workshop on Future Trends of Distributed Computing Systems","volume":"308 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123215328","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}

Recently, the simulation of different physical processes and systems has developed. Furthermore, the simulated system getting bigger and more sophisticated. Recently, the authors proposed a new hybrid architecture local area network (Hybrid-Meshnet). The Hybrid-Meshnet allows an insertion of data links into existing LANs. The authors simulate, investigate and visualize the operation and performance behaviour of Hybrid-Ethernet in comparison with conventional Ethernet. Through the event-driven simulation, a computer animation of the network operation is visualized. The simulator, in addition, generates the required data which is displayed as a 3D animated graph for performance investigation. Simulation results indicate that the performance of the Hybrid-Ethernet is improved with respect to the pure Ethernet. Moreover, the visualization technique is very efficient for seeing the unseen through simulation process.<<ETX>>","PeriodicalId":186762,"journal":{"name":"Proceedings of the Third Workshop on Future Trends of Distributed Computing Systems","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116299476","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 is shown that the CSCW and ODP community share mutual interests and have complementary aims and goals developed from different perspectives. Within the paper the authors provide a brief introduction to CSCW highlighting the requirements CSCW places on distributed systems. The development of an environment to support open CSCW systems is introduced and briefly described.
