At the same time, in the presence of significant amounts of the source code, fuzzing becomes a resource-intensive task. That’s why increasing the efficiency of fuzzing to reach needed code sections more quickly without reducing quality becomes an important line of research. The article deals with approaches to improve the efficiency of fuzzing both for kernel and for user-space software. On the other hand, on these amounts of program code, static code analysis produces a huge number of warnings about possible errors, and the main resources within this type of analysis are required not to obtain to result, but for analytical processing. In this regard, in the article considerable attention is paid to the approach of correlating the results of static and dynamic code analysis using the developed tool, which also allows to implement directed fuzzing in order to confirm the warnings of static analyzer, which significantly increases the efficiency of testing components of the protected OS Astra Linux.","PeriodicalId":33459,"journal":{"name":"Trudy Instituta sistemnogo programmirovaniia RAN","volume":"22 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89671475","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This article is devoted to entity linking, where Wikidata is used as an external knowledge base. We consider scientific terms in Russian as entities. Traditional entity linking system has three stages: entity recognition, candidates (from knowledge base) generation, and candidate ranking. Our system takes raw text with the defined terms in it as input. To generate candidates we use string match between terms in the input text and entities from Wikidata. The candidate ranking stage is the most complicated one because it requires semantic information. Several experiments for the candidate ranking stage with different models were conducted, including the approach based on cosine similarity, classical machine learning algorithms, and neural networks. Also, we extended the RUSERRC dataset, adding manually annotated data for model training. The results showed that the approach based on cosine similarity leads to better results compared to others and doesn’t require manually annotated data. The dataset and system are open-sourced and available for other researchers.","PeriodicalId":33459,"journal":{"name":"Trudy Instituta sistemnogo programmirovaniia RAN","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90760240","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to reduce cost of digital information ownership, some solutions use magnetic tape technology and special software to control medium and data. Considering the on-site infrastructure specifics and well-established workflows of data processing, these organizations build and support such systems mainly by their own efforts, what becomes an important task in seeking to acquire the technological sovereignty. This paper describes long-term data storage issues in the computing center of the Zababakhin All-Russia Research Institute of Technical Physics where mathematical modeling computations generate vast amount of scientific data. The architecture and functional composition of the developed Archive Data Storage System are given as well as its internal data model, the chunk grouping rules, and the low-level tape format used. The measures taken to ensure an archived data consistency, methods of storage media management and issues of archival fund maintenance, are also considered. The calculation scheme of a typical archive system site’s hardware configuration, sufficient to process archiving data flows existing in datacenter, is given.","PeriodicalId":33459,"journal":{"name":"Trudy Instituta sistemnogo programmirovaniia RAN","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82649254","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To tackle this problem, we propose to extend cost model with criteria that make dynamic compilation overhead relevant. The necessity to set up the optimizer criteria is due to the fact that the properties of various execution models impose restrictions on the efficiency of query plan execution using certain operator nodes. For example, the push-model used in the dynamic compiler is advantageous when executing queries using sequential scan. So, dynamic compilation makes sequential scan more efficient than index scan. Using index nodes in such a plan makes the value of the dynamic compilation method diminishing. To overcome these problems, it is proposed to configure the DBMS optimizer, so that it evaluates and takes into account the efficiency of using certain types of nodes when building a query plan with its subsequent dynamic compilation. This paper discusses the modification of the PostgreSQL planner to select the most efficient query execution plan based on hardware characteristics and the execution model of operator nodes with interpretation or compilation.","PeriodicalId":33459,"journal":{"name":"Trudy Instituta sistemnogo programmirovaniia RAN","volume":"26 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89411298","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
