System compositions and shared dependencies [chapter]

Dewayne E. Perry
1996 Lecture Notes in Computer Science  
In this paper, I discuss the problem of shared dependencies that is, substituting one of more interdependent components in a context, propose an approach for specifying such dependencies, and show h o  ...  Much of the work in con guration management has addressed the problems of version history and derivation.  ...  Shared Dependencies Shared dependencies among components arise naturally in the way w e build systems and are not necessarily the result of having built them badly.  ...

Efficient non-anonymous composition operator for modeling complex dependable systems [article]

Silvano Chiaradonna, Felicita Di Giandomenico, Giulio Masetti
2017 arXiv   pre-print
A new model composer is proposed to automatically generate non-anonymous model replicas in the context of performability and dependability evaluation.  ...  It is a state-sharing composer that extends the standard anonymous replication composer in order to share the state of a replica among a set of other specific replicas or among the eplica and another external  ...  INTRODUCTION Stochastic model-based evaluation is widely used to analyze the performability, dependability and performance of complex systems.  ...

Towards compositionality in execution time analysis

Sebastian Hahn, Jan Reineke, Reinhard Wilhelm
2015 ACM SIGBED Review  
Modern systems, such as multi-core processors, introduce even more timing dependencies -e.g. due to interference on shared resources between functionally independent programs running on different cores  ...  We highlight challenges and summarise open problems that arise in the context of compositional analyses.  ...  DFG as part of the Excellence Initiative of the German Federal and State Governments.  ...

Towards preserving correctness in self-managed software systems

Lieven Desmet, Nico Janssens, Sam Michiels, Frank Piessens, Wouter Joosen, Pierre Verbaeten
2004 Proceedings of the 1st ACM SIGSOFT workshop on Self-managed systems - WOSS '04  
We discuss the importance of consistent software compositions in the context of self-managed systems, and the need for a correctness-preserving adaptation process.  ...  In addition, to improve manageability and evolveability, software systems are extended with management capabilities and self-managed behavior.  ...  The dependency instance between the data sharing parties is only introduced during composition-time and is composition dependent.  ...

Adapting a General Semantic Interpretation Approach to Biological Event Extraction

Halil Kilicoglu, Sabine Bergler
2011 Workshop on Biomedical Natural Language Processing  
Similar to our earlier system, syntactic dependencies form the basis of our approach.  ...  In this spirit, we re-engineered and extended our event extraction system, emphasizing linguistic generalizations and avoiding domain-, event typeor text type-specific optimizations.  ...  Composition As mentioned above, the composition phase assumes simple entities, syntactic dependency relations and trigger expressions.  ...

How to capture dynamic behaviours of dependable systems

Salvatore Distefano
2009 International Journal of Parallel, Emergent and Distributed Systems  
This paper analyzes the reliability of fault tolerant/dependent/dynamic systems. The approach exploited is based on the concept of dependencies and their composition.  ...  From the system point of view, the reliability depends on the units' dynamics, on the interdependencies arising among such units (load-sharing, standby redundancy, interferences, etc) and on their reliability  ...  A behavior that can be represented by cooperating dependencies composition is the load sharing: the workload of a single unit, and consequently its dependability, depends on all the units sharing the overall  ...
