Thread-Level Speculation (TLS) can speculatively parallelized sequential dependences-carried programs in an aggressive manner by predicting dependent values in advance. However, the existing TLS execution model is error-prone and extra overhead will be introduced. To solve above problems, in this paper, a pure software-TLS execution model based on LLVM compiler is proposed with low-misspeculation and low-overhead. Firstly, an adaptive forking model is presented. This adaptive forking model can not only exploit higher degree of parallelism, but also reduce rollback rate. Secondly, an efficient memory management strategy is designed. With this strategy, the speculative status is separated from the non-speculative status, accelerating both communications among speculative threads and non-speculative threads, and its validation process with less time-consuming overhead. Experiments show that the presented speculative execution model can effectively extract sequential programs’ parallelism, and it can achieve a maximum speedup of 3.76, average 2.59 times speedup on 8-cores processor. Compared with the traditional TLS execution model, the improved model delivers a 9% performance improvement on average.","PeriodicalId":112143,"journal":{"name":"Proceedings of the 2021 2nd International Conference on Computing, Networks and Internet of Things","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115111773","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}

Most of the existing studies evaluate the importance of nodes in networks from a single structural perspective. Considering the local and global characteristics of the network, an identification algorithm of critical nodes in complex networks based on comprehensive topological importance (CTI) is proposed. The algorithm uses the theory of multiple attribute decision making (MADM) to quantitatively analyze the influence of different attributes on nodes and determine the comprehensive topology importance of nodes, which represents their structural importance in complex networks. Based on two simulation networks and five classical real networks, the proposed algorithm is proved to be superior to DC, LLS, P and WL indexes based on local information and BC indexes based on global information through the change of network efficiency under critical nodes attacking.","PeriodicalId":112143,"journal":{"name":"Proceedings of the 2021 2nd International Conference on Computing, Networks and Internet of Things","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125549970","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 paper focuses on the application scenarios of 5g smart power plant, and studies the applicable routing protocol and optimization scheme. The existing RPL uses a single link quality expected transmission times as the routing metric to calculate and compare the optimal paths. However, when some nodes in the network consume too much energy due to uneven load, the topology cannot be dynamically adjusted according to the routing metrics. In this paper, energy consumption is introduced to calculate the energy consumption of nodes. Combined with the expected number of transmissions, an improved RPL routing algorithm nb-npl based on energy balance is proposed. The algorithm not only takes into account the reliability of the link, but also considers the energy consumption information of the node, so that the node can avoid selecting those nodes with more energy consumption in the default routing selection process, which solves the problem that individual nodes are always in heavy use, and effectively performs the network life.","PeriodicalId":112143,"journal":{"name":"Proceedings of the 2021 2nd International Conference on Computing, Networks and Internet of Things","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115860752","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}

Valuable information can be extracted from this data through natural language processing. However, the process of information extraction can be difficult due to the informal forms of these texts. This paper aims to address this challenge by focusing on the conversion of Persian informal words to formal words by using the spell-checking approach. For this purpose, two datasets for formal and informal words were extracted from the four most visited news websites in Persian. Then Persian informal words were divided into multiple categories based on the level of changes required to build the formal equivalents. These were then converted to the formal forms according to their features. Statistical analyses combined with correction rules were used to produce a “candidate list” to find the best formal candidate equivalents. The performance of our conversion system was evaluated through people's comments extracted from the four most visited Persian (Farsi) news agencies. Results show that our proposed system can detect approximately 94% of the Persian informal words, with the ability to detect 85% of the best equivalent formal words. In addition, the comparison between the proposed system and two well-known Persian spell-checkers, Virastyar and Vafa, shows that in terms of detection and correction, the proposed system outperforms significantly. Further analysis shows that the time complexity of the proposed system is linear.","PeriodicalId":112143,"journal":{"name":"Proceedings of the 2021 2nd International Conference on Computing, Networks and Internet of Things","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133220915","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}
