The main goal of the system is to reduce the complexity of program parallelization. SAPFOR system is focused on the investigation of multilingual applications in Fortran and C programming languages. The low-level LLVM IR representation is used in SAPFOR for program analysis. This representation allows us to perform various IR-level optimizations to improve the quality of program analysis. At the same time, it loses some features of the program, which are available in its higher level representation. One of these features is the multi-dimensional structure of the arrays. Data dependence analysis is one of the main problems which should be solved to automate program parallelization. Moreover, such an analysis belongs to the class of NP-hard problems. Knowledge of the multidimensional structure of arrays allows in many cases to take into account the structure of index expressions in calls to arrays and reduce the complexity of the analysis. In addition, the use of multi-dimensional arrays allows us to use multi-dimensional processor matrix and to parallelize a whole loop nests, rather than a single loop in the nest. So, parallelism of a program is going to be increased. These opportunities are natively supported in the DVM system. This paper discusses the approach used in the SAPFOR system to recover the form of multi-dimensional arrays by their linearized representation in LLVM IR. The proposed approach has been successfully evaluated on various applications including performance tests from the NAS Parallel Benchmarks suite.","PeriodicalId":235410,"journal":{"name":"Russ.

A technique for prefixing operational task names with tactical labels of Priorities, Specifications and Affiliations is proposed. Label abbreviations are formed in such a way as to ensure the correct prioritization when sorting tasks in alphabetical order. The quadrants of the D. Eisenhower Priorities matrix are indicated by two-letter marks: important urgently (IF – Important, Fast); important indefinitely (IS – Important, Slow); not important, but promptly (UF – Unimportant, Fast): neither important nor urgent (US – Unimportant, Slow). The labels of the Specifications matrix for the information environment (RA, RI, SA, SI) are composed of mutually exclusive properties of the availability of the Network (I – Internet and A – Autonomous) and the presence of reduced or special functionality (R – Reduced and S – Special). Labels of the transport specification (TA, TB, TC, TP) allow you to sort tasks that require moving (T – Translocation) on an airplane (A), a bus (B), a car (C) and on foot (P – Pedestrian), respectively. Three-letter marks of Affiliations (belonging to an individual or legal entity) are formed from the first letters of the name, middle name and last name or name of the laboratory, company, project. Tactical marks accelerate decision-making when forming a daily list of operational tasks.","PeriodicalId":235410,"journal":{"name":"Russ. Digit. Libr.

The article published the results of the analysis of the use of 6 different microcomputers in various fields of activity. The purpose of the study is to determine the limiting factors affecting the efficiency of the targeted use of microcomputers. It has been established that for scientific and educational presentations, office and trading activities, it is currently advisable to use fanless microcomputers with a perforated case and an internal WiFi antenna, at least 4 GB of operational and 64 GB of permanent memory, and a microSD (TF) memory card slot, at least 128 GB, NTFS file system), Intel HD Graphics, USB3.0 and HDMI interfaces. Based on comparative experiments, methodological recommendations were created on optimizing the configuration of the hardware-software environment of microcomputers in stationary and mobile conditions. The problems of major updates to Windows 10, as well as the compatibility of Microsoft Store software and third-party manufacturers, are analyzed. It is recommended to specialize individual microcomputers for working with 32-bit applications; accounting and cryptographic programs; as well as conducting presentations with their video. Options for optimal configuration of the Start menu of the Windows 10 desktop are suggested. It is concluded that specialization in the hardware-software configuration of modern microcomputers allows you to increase the efficiency of using single devices and their paired systems in accordance with BYOD (Bring Your Own Device).","PeriodicalId":235410,"journal":{"name":"Russ.

Domain restriction is associated with the use of the Mathematical Sciences Classification System – MSC. A recommendation system is presented that allows you to create a list of possible experts for conducting scientific peer-reviewing on a mathematical article. The recommender system uses the MSC codes presented by the author of the article on the MSC2020 classifiers. If the codes MSC2000 or MSC2010 are indicated in the article, they are automatically converted to codes MSC2020. For each expert, the system supports a personal profile that contains a set of codes MSC2020, supplemented by numerical characteristics – weights calculated for each code in accordance with the system of accounting for competencies, preferences or refusals to participate in the review procedure. This set is automatically edited if the expert is included in the list of possible reviewers – the weights of several codes increase or decrease, as well as new codes are added. The recommendation system is implemented as an integrated tool (plug-in) of the Open Journal Systems (OJS) platform.
