In this paper, we will describe our realization of Go-dunov scheme which is good for autovectorization by compilers. Autovectorization of our code on the 1st and 2nd generations of Intel Xeon scalable processors gave twice performance growth. The energy efficiency growth is not so high because of the frequency degradation impact of AVX512 instructions. We also give an estimate value of carbon footprint for our variant of the code. Some numerical tests for code verification are also provided.","PeriodicalId":356772,"journal":{"name":"2021 Ivannikov Ispras Open Conference (ISPRAS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129794211","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}

Once they reach maturity and gain audience authors strive to improve performance by utilizing static or JIT compilation techniques. The latter helps to achieve the goal but at the expense of increased maintenance costs as source code splits into two loosely connected components. One solution to this problem is a program specialization method that utilizes existing interpreter's code and semi-automatically generates a compiler. In this paper we apply program specialization to the in-terpreter of the language of SQL expressions in PostgreSQL and show how the results compare against both the original interpreter and the built-in LLVM-based just-in-time compiler.","PeriodicalId":356772,"journal":{"name":"2021 Ivannikov Ispras Open Conference (ISPRAS)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127772005","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}

Accurate and efficient exception analysis is an important requirement for an industrial-level static analyzer. We propose a novel approach to manage exceptions while performing static symbolic execution of C# programs, which is able to process the newest features of the language, such as catch filters. In contrast to the approaches implemented in other static analysis tools, it is much more accurate, because it is path-sensitive thanks to consideration of exception conditions, field- and object-sensitive thanks to the representation of separate exceptions and its fields with distinct symbolic values. We evaluate our approach on a large set of open source projects having 4.2 mln LOC and nearly 2000 reviewed warnings of different types.","PeriodicalId":356772,"journal":{"name":"2021 Ivannikov Ispras Open Conference (ISPRAS)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122058321","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}

PDF documents are often untagged. In particular, this means that positions and the cell structure of tables are not designated explicitly. PDF table detection predicts bounding boxes of tables on document pages. Some of the predictions inevitably happen to be false. This negatively affects the accuracy of table structure recognition. We argue that the page layout analysis in pre- and post-processing can refine the table detection. We suggest pre-processing algorithms for the recognition of headings, running titles, paragraphs, and images in PDF pages. This allows selecting areas of interest inside pages where real tables can be placed. Then we use deep neural networks to predict tables only in these areas. We also propose post-processing algorithms to verify predictions and filter out false table candidates after table detection. Our empirical study shows that the proposed approach reduces errors in the table detection and improve the PDF table extraction overall.","PeriodicalId":356772,"journal":{"name":"2021 Ivannikov Ispras Open Conference (ISPRAS)","volume":"266 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116537250","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}

The problem considers two conflicting objectives: maximizing the quality of service of the network of charging stations and minimizing the deployment cost, when installing different types of charging stations. A metaheuristic algorithm based on the Non-dominated Sorting Genetic Algorithm is proposed to address the problem. The experimental analysis is performed on a real-world case study defined in Málaga (Spain) and it compares the proposed approach with a deterministic exhaustive search method. Results show that the proposed approach computes the most competitive solutions that represent different trade-offs between the quality of service and the installation costs, improving up to 5.79% over a deterministic exhaustive search.","PeriodicalId":356772,"journal":{"name":"2021 Ivannikov Ispras Open Conference (ISPRAS)","volume":"180 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130427537","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}
