This paper describes RPM5 — a promising package management toolset aimed to manage installation, update and removal of software in the Linux operating system. The toolset uses contemporary functionality of modern libraries and hardware in order to improve ease of software handling for both developers and users.
The article is devoted to a brief analysis of the main provisions of the initiative SEMAT — Software Engineering Method and Theory on the reconstruction of a unified theory of software engineering. The initiative developed by the OMG standard called Essence that defines the kernel and language for software engineering. The core represents the minimum number of entities involved in the process of creating a software system or are its result, and it introduces the relationship between these entities. Explain the main causes of the effectiveness of the proposed theory.
The article describes the results of the implementation of test data generation tools, by dividing the values of the input parameters of the system into equivalence classes to automate the complex functional testing of information XML-messages driven systems.
This article discusses comparative testing performance results of basic operations on documents in a Repository (IBM FileNet, Alfresco) for CMIS realization in comparison with Native API one. Some test results produce a great performance reduction in the case of CMIS using. The practical approaches of bounds definition in use of CMIS are determined.
The article topic is describing of the object-attribute approach (OAA) for computation organization in dataflow computing system (CS) for language systems creation (compilation, interpretation, semantic analysis) on the example of programming language creation for program model of dataflow supercomputer system. Is shown that the offered approach has advantages over the text analysis by means of the final state machine: widely functionality; possibility of calculations parallelization and realization on distributed CS; lack of a semantic gap between a programming language and the computer language, peculiar to modern VS with controlflow-architecture VS. Also possible application of OA-approach for natural language semantic analysis is described.
The problem of efficient use of resources of multiprocessor computer systems (AIM) architecture MPP (Massively Parallel Processing) for the settlement of specific parallel algorithms. It is proposed integrated indicator of the efficiency of the parallel program execution on a specific MBC, which takes into account both the hardware performance of the system and the quality of program parallelism.
Integration issues of two software products Metasonic Suite and Alfresco are regarded at the example of subject-oriented approach in service registry development and attendant business-process.
Various documentation types accompanying the software and the documentation life cycle are considered in the article. The documentation tool requirements are described for different document types. The documentation systems of two state-of-the-art types - CMS and Wiki - are considered, the usage cost estimation for standalone and hosted versions ofthese systems are compared in the article.
At the beginning of the paper, it is demonstrated that the technology of the most widely used SQL-oriented DBMS is inextricably linked with HDD technology. Features of HDD affect the data structures and algorithms for performing operations, methods of managing the buffer pool of the DBMS, transaction management, query optimization, etc. An alternative to a disk DBMS is an in-memory DBMS, storing databases entirely in the main memory. Despite the fact that in-memory DBMS has a number of advantages over disk DBMS, at present there is practically no competition. This, first of all, is due to natural limitations on the size of databases, inherent in in-memory DBMS. At present, new types of data storage hardware have appeared: SSD — block solid-state drives and SCM — storage-class memory (non-volatile main memory). SSD characteristics made it expedient to develop a DBMS in terms of their exclusive use, so far no such DBMS has been created, and SSDs are used simply instead of HDDs in DBMS that do not take their features into account. The availability of SCM allows one to radically simplify the architecture of the database and significantly improve their performance. To do this, you need to review many of the ideas used in disk-based databases.
We report approach for the generation of parallel uncorrelated streams of preudorandom numbers. We apply our method to the number of modern and reliable pseudorandom number generators and develop particular algorithms for initialization of parallel streams. Particularly, each of our GPGPU realizations can produce exactly the same output sequence as the original algorithm.
The problems of monitoring the integrity of a complex automated banking systems when tracking. Given the notion of the integrity level of the automated system described using the evaluation of the level of integrity of the planning methodology, testing and assessment of the adequacy of its results, as well as methods of assessing the effectiveness of monitoring the integrity of the automated banking system.
The paper discusses the problem of efficient distribution of data across local resources (RAM) multiprocessor computing systems architecture with MPP (Massive Parallel Processing). In order to minimize downtime calculators during the exchange of data between nodes multiprocessor computing systems. It is proposed to formalize source-level and optimization technique
