The MOOSE structure is aimed at a loosely coupled distributed system in which several processors are connected over a local area network. It is implemented in the high-level distributed programming language SR on several Sun-2 and Sun-3 workstations running the Unix operating system and connected by an Ethernet. The MOOSE shared memory has been designed with customizable features for efficiency of implementation in such an environment. This enables the communication and computation performance of parallel algorithms on non-shared-memory hardware to be studied. If the application is run in the background on several network nodes, automatic load balancing is achieved and the programs may be tolerant of node failure during the computation.<<ETX>>","PeriodicalId":342782,"journal":{"name":"Proceedings of the Second Workshop on Workstation Operating Systems","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125949276","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}

These mechanisms are used to interface with the different types of devices involved in multimedia conference applications and to direct information flow among them. They are concerned with teleconferencing applications with which people in different offices can talk to each other while simultaneously editing the same file, debugging the same program, or working on some other arbitrary applications. Users engaged in teleconferencing may use multimedia workstations equipped with peripherals such as telephone handsets, image scanners, network interfaces, and mass storage. In the prototype system, the workstations are connected to an experimental fast packet switch capable of switching voice, data, and video on a single network.<<ETX>>","PeriodicalId":342782,"journal":{"name":"Proceedings of the Second Workshop on Workstation Operating Systems","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116839893","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 Raven operating system is intended for use in a variety of applications, such as office systems and control systems. It is intended to work as a high-speed, fault-tolerant system. Raven includes both a programming language and an operating system. Raven is object-oriented in that it supports multiple inherited types. It is fault tolerant in that it supports persistent objects, recoverable objects, and atomic transactions. The major emphasis of the work is the overall design of the language and system, distributed configuration management, distributed single-level object store, RAM-based high-speed transaction management, and object-based parallel communication. All of these areas of work are being developed within the context of autonomous administration domains.<<ETX>>","PeriodicalId":342782,"journal":{"name":"Proceedings of the Second Workshop on Workstation Operating Systems","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127823760","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}

They are motivated by their distributed file system which uses stateful servers to support a high-performance distributed caching system. For reliability, a server's state is replicated in the main memory of other hosts so that the system can recover from the failure of a server. After a server reboots, its clients help it rebuild its internal state. The authors point out that as networks and processors get faster, but disks do not, relying on other hosts will be more efficient than using disks.<<ETX>>","PeriodicalId":342782,"journal":{"name":"Proceedings of the Second Workshop on Workstation Operating Systems","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114194574","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 argument is couched in terms of experience with the Andrew file system (AFS) but the author believes that it generalizes to many environments. He discusses in some detail a replication library his group built, on top of which they built all of the AFS administrative servers. This library, named Ubik, is interesting for three reasons. First, it has a very simple programming interface, making it relatively easy to understand. Second, the library is quite easy to implement, while still being useful for a large class of server applications. Finally, the library uses an interesting nonblocking (in the database sense) commit protocol, providing good write as well as read availability. The author outlines Ubik's goals, gives an overview of it, and describes its quorum completion algorithm in some detail.<<ETX>>","PeriodicalId":342782,"journal":{"name":"Proceedings of the Second Workshop on Workstation Operating Systems","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1989-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115124964","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}
