Efficient Fault Injection Based Assessment Of Software Implemented Hardware Fault Tolerance

Efficient Fault-injection-based Assessment of Software-implemented Hardware Fault Tolerance

Software-Implemented Hardware Fault Tolerance

Software-Implemented Hardware Fault Tolerance addresses the innovative topic of software-implemented hardware fault tolerance (SIHFT), i.e., how to deal with faults affecting the hardware by only (or mainly) acting on the software. The first SIHFT techniques were proposed and adopted several decades ago, but they have been the object of new interest in the past few years, mainly due to the need for developing low-cost safety-critical computer-based applications in fields such as automotive, biomedics, and telecommunications. Therefore, several new approaches to detect, and when possible correct, transient and permanent faults in the hardware have been recently proposed. These approaches are innovative (with respect to those proposed in the past) since they are of higher applicability (often starting from the source-level code of an application) and generality, being capable of coping with many different fault types. The book presents the theory behind software-implemented hardware fault tolerance, as well as the practical aspects related to put it at work on real examples. By evaluating accurately the advantages and disadvantages of the already available approaches, the book provides a guide to developers willing to adopt software-implemented hardware fault tolerance in their applications. Moreover, the book identifies open issues for researchers willing to improve the already available techniques.

Proceedings of the 10th Ph.D. Retreat of the HPI Research School on Service-oriented Systems Engineering

Design and Implementation of service-oriented architectures imposes a huge number of research questions from the fields of software engineering, system analysis and modeling, adaptability, and application integration. Component orientation and web services are two approaches for design and realization of complex web-based system. Both approaches allow for dynamic application adaptation as well as integration of enterprise application. Commonly used technologies, such as J2EE and .NET, form de facto standards for the realization of complex distributed systems. Evolution of component systems has lead to web services and service-based architectures. This has been manifested in a multitude of industry standards and initiatives such as XML, WSDL UDDI, SOAP, etc. All these achievements lead to a new and promising paradigm in IT systems engineering which proposes to design complex software solutions as collaboration of contractually defined software services. Service-Oriented Systems Engineering represents a symbiosis of best practices in object-orientation, component-based development, distributed computing, and business process management. It provides integration of business and IT concerns. The annual Ph.D. Retreat of the Research School provides each member the opportunity to present his/her current state of their research and to give an outline of a prospective Ph.D. thesis. Due to the interdisciplinary structure of the research school, this technical report covers a wide range of topics. These include but are not limited to: Human Computer Interaction and Computer Vision as Service; Service-oriented Geovisualization Systems; Algorithm Engineering for Service-oriented Systems; Modeling and Verification of Self-adaptive Service-oriented Systems; Tools and Methods for Software Engineering in Service-oriented Systems; Security Engineering of Service-based IT Systems; Service-oriented Information Systems; Evolutionary Transition of Enterprise Applications to Service Orientation; Operating System Abstractions for Service-oriented Computing; and Services Specification, Composition, and Enactment.
