Each reliable object is characterized by its persistent state and methods. It is mapped onto a server which manages the object's persistent state and method calls. In order to recover a global consistent state of objects in the event of failure, a solution based on dynamic atomic actions was implemented. Servers are running on a fault tolerant version of an extended MACH microkernel.<<ETX>>","PeriodicalId":147994,"journal":{"name":"[1993] Proceedings of the Second International Conference on Parallel and Distributed Information Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129717619","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}

Preliminary performance results for Omega are presented to demonstrate the feasibility of a parallel object-based system.<<ETX>>","PeriodicalId":147994,"journal":{"name":"[1993] Proceedings of the Second International Conference on Parallel and Distributed Information Systems","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124539439","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 approach makes possible exploring a search space large enough to include zigzag trees which are intermediate between left-deep and right-deep trees. Zigzag trees are shown to provide better response time than right-deep trees in the case of limited memory. Because DBS3 implements a parallel dataflow execution model, this approach applies to both shared-memory and distributed-memory architectures. Performance measurements run using the DBS3 prototype show the advantages of zigzag trees under various conditions.<<ETX>>","PeriodicalId":147994,"journal":{"name":"[1993] Proceedings of the Second International Conference on Parallel and Distributed Information Systems","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131602685","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 provides additional support for planning applications, which are long-running applications that may need to respond to changes in the underlying multidatabase. Interactions and the multidatabase architecture that they run on are described, and synchronization of Interactions is discussed. The nature of events, which the applications can use to monitor changes in the information in the multidatabase is described, and how they are detected and how to respond to them are defined. This response usually involves semantically undoing part of at least one Interaction, so a brief description of how recovery works in that situation is given.<<ETX>>","PeriodicalId":147994,"journal":{"name":"[1993] Proceedings of the Second International Conference on Parallel and Distributed Information Systems","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115147723","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 particular, four multiway join query optimizers have been implemented and a simulator developed to investigate the effect of skewed tuple distribution on these techniques. Dynamic load balancing is found to very critical to the performance of shared-nothing (SN) systems, particularly when the system is large. Since load balancing becomes more difficult for larger systems, one should exploit interjoin parallelism in order to limit the number of processing nodes used for each join operation. The skew issue must be considered during query optimization to achieve the best performance. The load balancing techniques proposed can easily be extended to support interquery parallelism in a multiuser environment.<<ETX>>","PeriodicalId":147994,"journal":{"name":"[1993] Proceedings of the Second International Conference on Parallel and Distributed Information Systems","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132078679","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}
