Information Technology of Software Architecture Structural Synthesis of Information System
Information technology of information system software architecture structural synthesis is proposed. It is used for evolutionary models of the software lifecycle, which provides configuration and formation of software to control the realization and recovery of computing processes in parallel and distributed computing resources structures. The technology is applied in the framework of the software requirements analysis, design of architecture, design and integration of software. Method of combining vertices for multilevel graph model of software architecture and automata-based method of checking performance limitations to software are based on the advanced graph model of software architecture. These methods are proposed in the framework of information technology and allow forming a rational structure of the program, as well as checking for compliance with the functional and non-functional requirements of the end user.The essence of proposed information technology is in displaying of the customer's requirements in the current version of the graph model of program complex structure and providing a reconfiguration of the system modules. This process is based on the analysis and processing of the graph model, software module specifications, formation of software structure in accordance with the graph model, software verification and its compilation

Event Stream Processing with Multiple Threads
Current runtime verification tools seldom make use of multi-threading to
speed up the evaluation of a property on a large event trace. In this paper, we
present an extension to the BeepBeep 3 event stream engine that allows the use
of multiple threads during the evaluation of a query. Various parallelization
strategies are presented and described on simple examples. The implementation
of these strategies is then evaluated empirically on a sample of problems.
Compared to the previous, single-threaded version of the BeepBeep engine, the
allocation of just a few threads to specific portions of a query provides
dramatic improvement in terms of running time
Experiences from Software Engineering of Large Scale AMR Multiphysics Code Frameworks
Among the present generation of multiphysics HPC simulation codes there are
many that are built upon general infrastructural frameworks. This is especially
true of the codes that make use of structured adaptive mesh refinement (SAMR)
because of unique demands placed on the housekeeping aspects of the code. They
have varying degrees of abstractions between the infrastructure such as mesh
management and IO and the numerics of the physics solvers. In this experience
report we summarize the experiences and lessons learned from two of such major
software efforts, FLASH and Chombo.Comment: Experience Repor
