Regenerating codes can minimize the network bandwidth required to recover the data lost on the failed nodes. Minimum Storage Regenerating (MSR) code is a class of regenerating codes that can maximize the storage efficiency, meanwhile minimizing the repair bandwidth. The original MSR code via Product Matrix (PM) provides a means for single failed node recovery. In this work, an algorithm of recovering multiple failed nodes concurrently with the minimum feasible bandwidth will be proposed, extending the framework of the original PM MSR code. Based on the proposed strategy, the needed bandwidth for centralized and distributed recovery policies, which are the two major categories of repairing policies, will be explicitly expressed against the coding parameters and the number of failed nodes, hence numerical comparison can be made between them. Moreover, the impact of Repairing Degree (the number of surviving nodes from which the assistant data are downloaded ) on the bandwidth cost will be studied to help make optimal decision in practical storage systems.","PeriodicalId":166357,"journal":{"name":"Proceedings of the 12th IEEE/ACM International Conference on Utility and Cloud Computing Companion","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114955398","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}

It consists of many steps, one of which is data mining, each aiming to complete a discovery task, and accomplished by the application of a discovery method [1]. On this subject, the Semantic Web (SW) is an effort to interchange unstructured data over the Web into a structured format that is processable not only by human beings but also by computers [2]. The SW creates a distributed framework to publish, query, and reuse information [3]. The key backbones of SW are ontologies and annotations that provide semantics for raw data are known as Resource Description Framework (RDF) data [4]. The RDF data can also be published over Linked Open Data (LOD) cloud. To highlight the vision of SW, we would like to run a tutorial. The main goal of this tutorial is to provide background knowledge about SW, RDF, Web Ontology Language (OWL), SPARQL, knowledge graph, graph databases, and SW-based applications. This tutorial will show how SW provides explicit models of the terminology of a domain to improve information access.","PeriodicalId":166357,"journal":{"name":"Proceedings of the 12th IEEE/ACM International Conference on Utility and Cloud Computing Companion","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134441991","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}

However, the response time, reliability and other quality-of-service (QoS) properties of these services are often uncertain. As such, ensuring that service-based systems achieve their QoS requirements is very challenging. This talk will describe how recent advances in probabilistic model learning, analysis and synthesis can help address this challenge both during service-based system design and verification, and at runtime.","PeriodicalId":166357,"journal":{"name":"Proceedings of the 12th IEEE/ACM International Conference on Utility and Cloud Computing Companion","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129099679","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}

Fog computing has recently become a popular computing paradigm that can provide computing resources close to the end users and solve multiple issues with the current cloud-only systems. However, the scheduling of workflow applications in the cloud-fog environment to find the best tradeoff between makespan and price is facing enormous challenges. To address such a challenge, this paper presents an adaptation of the Path-Clustering Heuristic to the cloud-fog environment for multiple workflows. Firstly, we define the models for workflow execution time and resource cost in fog computing.Afterwards, we describe the newly proposed algorithms. We validate the efficiency of the algorithms with extensive simulation. Experimental results show that our scheduling adaptation achieves better performance while keeping similar costs compared to others.","PeriodicalId":166357,"journal":{"name":"Proceedings of the 12th IEEE/ACM International Conference on Utility and Cloud Computing Companion","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130402102","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 research in this paper is motivated towards characterising and estimating the time taken to offload a service using containers, which is investigated in the context of the 'Save and Load' container migration technique. To this end, the research addresses questions such as whether fog offloading can be accurately modelled and which system and network related parameters influence offloading. These are addressed by exploring a catalogue of 21 different metrics both at the system and process levels that is used as input to four estimation techniques using a collective model and individual models to predict the time taken for offloading. The study is pursued by collecting over 1.1 million data points and the preliminary results indicate that offloading can be modelled accurately.","PeriodicalId":166357,"journal":{"name":"Proceedings of the 12th IEEE/ACM International Conference on Utility and Cloud Computing Companion","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131025774","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}
