The authors compare such measures for the dynamic supporting algorithm, the dynamic supporting (G) algorithm, and other algorithms, e.g., the available copies and the majority voting algorithms. Since replicas and votes are conceptually separated, the two dynamic supporting algorithms could achieve very high availability and reliability while still keeping storage cost very low, especially with only two replicas. Both stochastic analysis and simulation results are reported. The performance improvement of the dynamic supporting algorithms is demonstrated by the results.<<ETX>>","PeriodicalId":286518,"journal":{"name":"[1992] Proceedings.

The key idea behind this tool design is to abstract run-time activities and turn them into graphical representations that move and vary in location, size, and color. With proper abstractions, it establishes a technical foundation for monitoring, analyzing, and improving complex parallel algorithms. It represents animated views in an informative and coherent manner. There are two unique attributes that distinguish the animation tool from others: (1) it provides a general simulation environment for analyzing parallel algorithms with arbitrary program structures and sizes; and (2) it allows the visualization for computation status of parallel processes and their run-time interactions.<<ETX>>","PeriodicalId":286518,"journal":{"name":"[1992] Proceedings.

ORDIT focuses on the representation of organizational requirements in the design of socio-technical systems which are intended to emphasize the relationships between organizational structure and information technology (IT) systems. The five main components of the ORDIT methodology are discussed, with a focus on the process model and the enterprise model. A process model is a model of the process of eliciting and modeling requirements. One of the main characteristics of the ORDIT process model is the way it has separated these two functions and has shown the relation between them. The ORDIT project has devised an enterprise modeling language to represent the structure of the organization to serve two related but distinct purposes: to determine the requirements owners and their positions and roles within the organization; and to determine the users and their roles and responsibilities within the organization.<<ETX>>","PeriodicalId":286518,"journal":{"name":"[1992] Proceedings.

The author analyzes how properties are related amongst each other and proposes one method to identify collections of properties and relationships between properties. He advocates that prior to the development of computer-based systems, it is necessary to identify the properties of the system development and the relationships between the properties. From an initial list of properties, the required set of properties of the software development can be selected and refined. An extract of one survey of properties is presented. The survey is a particular application of the method presented.<<ETX>>","PeriodicalId":286518,"journal":{"name":"[1992] Proceedings.

The authors provide an algorithm based on coding theory to significantly reduce the number of signatures needed to precisely diagnose differing pages in remotely located file copies. The method needs only one message transmission. A unique feature of this method is the ability to precisely diagnose up to t differing pages with just 2t signatures, independent of the files size. The maximum number of pages in a file is determined only by the number of bits in a signature. If a signature has m bits, the proposed technique can precisely identify t(t<2/sup m-1/ page differences in a file that has up to 2/sup m/-1 pages.<<ETX>>","PeriodicalId":286518,"journal":{"name":"[1992] Proceedings.

WARASA is an extension to C/sup ++/ to allow a programmer to develop concurrent programming. In designing WARASA, the parallel mechanisms on the Mach operating system are combined with the object-oriented paradigm. It enables users to develop concurrent programs easily and efficiently, because some implementation details such as locking and unlocking which programmers would have to know to write parallel programs are hidden. An overview of WARASA is given. The features of WARASA class models are discussed. Some applications are shown to demonstrate WARASA's expressive power.<<ETX>>","PeriodicalId":286518,"journal":{"name":"[1992] Proceedings.
