In the paper, we describe a metamodel to represent dynamics of AADL-models. The metamodel allows to visualize step-by-step a process of models' behavioral aspects analysis. In particular, it essentially helps to debug behavioral specifications. In the paper, we consider examples of the metamodel usage to represent dynamics for the following two aspects of AADL-models: 1) simulation of a modelled system on the basis of a Behavior Annex specification;2) failure modes and effects analysis on the basis of an Error Model Annex specification. We also present a stepwise visualization tool (engine and applications for both mentioned examples) that is implemented in MASIW framework for design of modern avionics systems. © 2017 IEEE.

Embedded devices may be significantly constrained in main memory, storage and CPU loads they can accommodate. The smaller the program, the faster it is loaded into memory. The smaller the system image, the cheaper can be production of the device. There are two ways to approach system image minification. The first way is to carefully write software adding no unnecessary parts from the start. The second way is to use existing software with unnecessary parts removed. In this work we implement the latter approach. Our work is concerned with eliminating unused code and data from dynamically linked programs; for statically linked programs, simple linker analysis is sufficient and has already been implemented.

The next phase of LHC Operations – High Luminosity LHC (HL-LHC), which is aimed at ten-fold increase in the luminosity of proton-proton collisions at the energy of 14 TeV, is expected to start operation in 2027-2028 and will deliver an unprecedented scientific data volume of multi-exabyte scale. This amount of data has to be stored and the corresponding storage system should ensure fast and reliable data delivery for processing by scientific groups distributed all over the world. The present LHC computing and data processing model will not be able to provide the required infrastructure growth even taking into account the expected hardware technology evolution. To address this challenge the new state-of-the-art computing infrastructure technologies are now being developed and are presented here. The possibilities of application of the HL-LHC distributed data handling technique for other particle and astro-particle physics experiments dealing with large-scale data volumes like DUNE, LSST, Belle-II, JUNO, SKAO etc. are also discussed.

In this paper application of the OpenFOAM solver QGDFoam for numerical simulation of transonic viscous flows is considered. The developed solver, which implements regularized or quasi- gas dynamics (QGD) algorithms, is validated using the transonic low-Re jet flow case (Ma=0.9, Re=3600). The conducted numerical simulations allow the assessing applicability of the solver for modelling hydrodynamic instabilities and their interaction with transonic flow. Results of the numerical simulations are compared with experimental observations and Navier-Stokes-based code simulation. Results of the present study formulate a guideline for choosing (values of) QGD-algorithm tuning parameters.

In this paper we present preliminary results of the multi-fractal analysis for describing the behavior of turbulence evolution in the wake behind two model wind turbines using the program ImaCal. The wind energy is an important component of renewable energy sources. Nowadays the research community focuses on studying the turbulent wakes behind wind turbines and its interactions with the Atmospheric Boundary Layer. For finding the fractal dimension a multi-fractal analysis was performed using the results of a numerical simulation of the flow over two model wind turbines. The latter was carried out by means of the Large Eddy method with the Lagrangian Dynamic Smagorinsky subgrid model. The SOWFA library was employed as a part of OpenFoam software to perform the simulation.

Approach is offered to the formal specification of Standard Life Cycle (LC) of the program systems (PS) by the ontology facilities with purpose automation and generation of the variants LC for making the appropriate kinds process for development different PS. Ontological approach to presentation LC model of the standard ISO/IEC 12207-2007 is included the specification of general, organizational and support processes. These processes are presented in the subject-oriented DSL, which than transformed to XML for realization. One of the processes, the testing process is given in terms of Protégé systems. An eventual result of this system Protégé got generally at accepted to the XML, suitable for implementation tasks testing PS on computer.

International Workshop on Variability-intensive systems Testing, Validation, and Verification

Automatic generation and simulation of test programs is known to be the main means for verifying microprocessors. The problem is that test program generators for new designs are often developed from scratch with little reuse of well-tried components. State-of-the-art tools, like Genesys-Pro and RAVEN, meet the challenge by using a model-based approach, where a microprocessor model is separated from a platform-independent generation core. However, there is still a problem. Developing a microprocessor model is rather difficult and usually requires deep knowledge of the inner-core structure and interfaces. In this paper, we describe a concept of a reconfigurable test program generator being customized with the help of architecture specifications and configuration files, which describe parameters of the microprocessor subsystems (pipeline, memory, and others). The suggested approach eases the model development and makes it possible to apply the model-based testing in the early design stages when the microprocessor architecture is frequently modified. © 2011 IEEE.

Verification of Linux kernel modules and especially device drivers is a critically important task. However, due to the special nature of the kernel operation, it is very challenging to perform runtime analysis of particular kernel modules of interest without adverse influence on the rest of the kernel. Methods and tools for addressing this challenge are the main subject of this paper. The basic method for low-influence runtime analysis of interacting software modules is call interception. Shadow state techniques represent another method. In this paper, we discuss these methods including three different approaches to implement call interception. Conclusions are made about the most suitable ways for runtime analysis of kernel modules. Finally, we present KEDR framework, an extensible runtime analysis system for Linux kernel modules, which deploys these approaches to perform different types of analysis. The system can be used by the developers of kernel modules and, in particular, may be useful for building automated driver verification systems. © 2011 IEEE.
