Decomposition Technique and UltraSAN Software Tool for Performability Evaluation
نویسندگان
چکیده
The analysis of performability for large and complex computer systems during design phase, although difficult, is an important activity which contributes to reducing lead times. A pre-requisite of analysis is modelling and a decomposition technique is described. This technique enables the designer to divide the system’s function successively into smaller sub-functions and to treat each sub-function in terms of real components. Stochastic activity networks representation of components are built and then composed into a complete model. The technique is an extension of the method underlying the UltraSAN software tool.

متن کاملPerformability Modelling Tools and Techniques
Over the last decade considerable effort has been put in the development of techniques to assess the performance and the dependability of computer and communication systems in an integrated way. This so-called per-formability modelling becomes especially useful when the system under study can operate partially, which is for instance the case for fault-tolerant computer systems and distributed s...
متن کاملStochastic Activity Networks: Formal Definitions and Concepts
Stochastic activity networks have been used since the mid1980s for performance, dependability, and performability evaluation. They have been used as a modeling formalism in three modeling tools (METASAN, UltraSAN, and Möbius), and have been used to evaluate a wide range of systems. This chapter provides the formal definitions and basic concepts associated with SANs, explaining their behavior an...

Meyer, J.F,, Performability: a retrospective and some pointers to the future, Performance Evaluation 14 (1992) 139-156. As computing and communication systems become physically and logically more complex, their evaluation calls for continued innovation with regard to measure definition, model construction/solution, and tool development. In particular, the performance of such systems is often de...
