....be used to study the general behavior of applications, since it is a language based simulator. DRTSS is related to STRESS. DRTSS is a high level simulation framework that allows its users to easily construct discrete event simulators of complex, multi paradigm, distributed real time systems [17]. The DRTSS framework is quite di#erent from STRESS, although they are closely related. It contains a set of algorithms and protocols from which one can pick the appropriate ones and build a simulator. New algorithms and protocols can be added to the original set. It has support for searching for ....

....code for STRESS, but they were unsuccessful, so it was not possible to improve STRESS. These flaws make STRESS unsuitable. 5. 3 DRTSS DRTSS is a simulation framework that allows its users to easily construct discrete event simulators of complex, multi paradigm, distributed real time systems [17]. The DRTSS framework is quite di#erent from STRESS, although they are closely related. DRTSS has no language where task behavior can be specified. That it something that is necessary for achieving the goals of the work and excludes DRTSS as a possible solution. DRTSS is a part of the PERTS ....

....Using a library of scheduling algorithms and resource access protocols, PERTS supports the evaluation of new and competing designs. Schedulability analysis is provided through a graphical interface, and support is provided for heterogeneous systems. Recently, PERTS was complemented by DRTSS [49], a powerful simulation framework that provides a suite of task assignment, task scheduling, and resource access protocols, for hard and soft real time systems with capabilities for static and dynamic task assignment. CAISARTS [22] is a rule based system that can be used for obtaining advice on ....

....timing aspects, such as scheduling [28, 3, 47] which are particularly relevant and important for real time systems. A Petri net model can very well be used for scheduling simulation and has considerable advantages in flexibility and extendibility over conventional scheduling simulators (e.g. [48]) which only allow more or less predefined task precedence structures. Even though there exist a lot of theoretical results about schedulability in single processor real time systems [47] scheduling simulation is still necessary [18, 22, 8] when non ideal behavior of system components (e.g. ....

....DRTSS is not oriented towards the performance analysis of scheduling algorithms. The tool set was developed within the European Community ESPRIT programs TRACS and MORIS. It is currently not publicly available. 4 PERTS tool set The PERTS (Prototyping Environment for Real Time Systems) tool set [18, 17, 14, 15, 23, 24, 20, 19] consists of a schedulability analyzer and a simulator. 4.1 PERTS SAT For the schedulability analyzer [14, 15, 23] the model of the real time system is specified using a graphical editor for task graph and resource graph. The resource graph can specify several nodes with processors and other ....

....algorithms and resource access protocols must be identical for all nodes. The PERTS SAT is the most comprehensive scheduling analyzer among all the tools in this survey, however it does not seem to extendible. 3 4. 2 DRTSS PERTSSim Major features of DRTSS (PERTSSim in the commercial version) [18, 17, 24, 20, 19] are the output analysis unit, the parameter variation (search) engine, and the live task model. The output analysis unit can be programmed with a proprietary language to trigger on and process primitive simulator events (such as task started, task preempted, etc. to extract the particular ....

....very few tools which allow end users to define their own scheduling policy, task model and so on in an easy way. For example, Kuo and Mok [4] and Song [5] tested some specific protocols through simulation but their work can hardly be extended to include other approaches. DRTSS is a general tool [6] which has a single formalism to describe both the scheduling policy and the task set, thus allowing a user to specify his own. Unfortunately DRTSS is not oriented to the performance analysis of scheduling algorithm but to modeling and verification of real time applications. A more general tool ....
