Download or read book Design Guidelines for a Monitoring Environment Concerning Distributed Real time Systems written by Aida Omerovic and published by Fagbokforlaget. This book was released on 2004 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: While the dependability requirements of distributed real-time systems are expanding, there is currently no framework for defining and mapping these requirements into the system design and operation. A method of controlling and achieving the dependability level is real-time monitoring, which measures the degree of requirements fulfilment, relates it to the pre-defined, measurable system-level expectations and dynamically adapts the system, based on quality metrics, risk analysis, cost evaluation, control theory, neural networks, data acquisition and system knowledge management. The book deduces a framework to reveal, define, quantify, measure, analyse, design, implement, test, monitor and enhance dependability (functional and non-functional) requirements of a distributed system with real-time constraints. It is presented how the framework can be applied throughout all life-cycle stages, under varying constraints and with maximised cost effectiveness. An overview of the tools and methodologies applicable has been given and an integrated and generalised architecture for ensuring continuous fulfilment of system requirements, proposed. The framework provides a multilevel specification mechanism to establish the preservation of system requirements. This ensures the correct functioning of system through adaptations at run time. Among the benefits are controlled access and coordinated resource sharing in accordance with service-level agreement policies, multi-stakeholder interest preservation, transparency with respect to location, naming, performance etc., achievement of quality of service on demand, decentralisation, seamless integration of resources and applications, as well as increased predictability. READERSHIP: The intended audience is broad: real time and distributed systems scientists and developers, software engineers, students, quality assurance managers, contractors, users, service providers and all those searching for an alternative approach to handling and ensuring automated control of fulfilment of system requirements. Moreover, those needing a handbook on contract negotiations and a method of tracing operational results back into system requirements of long lived projects with high dependability and integrity demands.

Available in PDF, EPUB and Kindle. Book excerpt: NATO's Division of Scientific and Environmental Affairs sponsored this Advan ced Study Institute because it was felt to be timely to cover this important and challengjng subject for the first time in the framework of NATO's ASI programme. The significance of real-time systems in everyones' life is rapidly growing. The vast spectrum of these systems can be characterised by just a few examples of increasing complexity: controllers in washing machines, air traffic control systems, control and safety systems of nuclear power plants and, finally, future military systems like the Strategic Defense Initiative (SDI). The import ance of such systems for the well-being of people requires considerable efforts in research and development of highly reliable real-time systems. Furthermore, the competitiveness and prosperity of entire nations now depend on the early app lication and efficient utilisation of computer integrated manufacturing systems (CIM), of which real-time systems are an essential and decisive part. Owing to its key significance in computerised defence systems, real-time computing has also a special importance for the Alliance. The early research and development activities in this field in the 1960s and 1970s aimed towards improving the then unsatisfactory software situation. Thus, the first high-level real-time languages were defined and developed: RTL/2, Coral 66, Procol, LTR, and PEARL. In close connection with these language develop ments and with the utilisation of special purpose process control peripherals, the research on real-time operating systems advanced considerably.

Available in PDF, EPUB and Kindle. Book excerpt: Work on the monitor has concentrated on three aspects: furthering the conceptual design, implementing the lower level mechanisms of the monitor and designing and implementing the relational monitor. At this point, we have a fairly complete idea of the tasks the various components perform and how these components will interact. The components are: StarMon, low level data collection under the StarOS operating system on CM*, consisting of two processes: Accountant, interfaces to the Simon Accountant via the EtherNet; MonProc, performs name translation, enabling of events and miscellaneous services. Medic, low level collection under the Medusa operating system on CM*, Simon Accountant interfaces with the resident monitor (either StarMon or Medic using a system-independent protocal; Simon, the computing engine' for deriving high level information from event records; Control, accepts queries from the user in a declarative language and translates these queries into update networks for Simon. At this point, the first three components are nearing completion. Once their condition is stable, sensors will be placed throughout both StarOS and Medusa to provide a source of event records for Simon. The structure of Simon has been implemented, although more work is necessary. The Control component has been partially designed and is in the early stages of implementation. Also the a Sensor Definition facility has been designed and implemented.

Download or read book Runtime Monitoring of Timing Constraints in Distributed Real time Systems written by University of Michigan. Dept. of Electrical Engineering and Computer Science. Computer Science and Engineering Division and published by . This book was released on 1994 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "Embedded real-time systems often operate under strict timing and dependability constraints. To ensure responsiveness, these systems must be able to provide the expected services in a timely manner even in the presence of faults. In this paper, we describe a run-time environment for monitoring of timing constraints in distributed real-time systems. In particular, we focus on the problem of detecting violations of timing assertions in an environment in which the real-time tasks run on multiple processors, and timing constraints can be either inter-processor or intra-processor constraints. Constraint violations are detected at the earliest possible time by deriving and checking intermediate constraints from the user-specified constraints. If the violations must be detected as early as possible, then the problem of minimizing the number of messages to be exchanged between the processors becomes intractable. We characterize a sub-class of timing constraints that occur commonly in distributed real-time systems and whose message requirements can be minimized. We also take into account the drift among the various processor clocks when detecting a violation of a timing assertion. Finally, we describe a prototype implementation of a distributed run-time monitor."

Available in PDF, EPUB and Kindle. Book excerpt: Computer scientists have long appreciated that the relationship between algorithms and architecture is crucial. Broadly speaking the more specialized the architecture is to a particular algorithm then the more efficient will be the computation. The penalty is that the architecture will become useless for computing anything other than that algorithm. This message holds for the algorithms used in real-time automatic control as much as any other field. These Proceedings will provide researchers in this field with a useful up-to-date reference source of recent developments.
