Thanks to the increased data availability and computational power, such as Graphic Process Units (GPU), training deep networks - a time-consuming process - became possible. Cloud computing is an excellent option to acquire the computational power to train these models since it provides elastic products with a pay-per-use model. Amazon Web Services (AWS), for instance, has GPU-based virtual machine instances in its catalog, which differentiates themselves by the GPU type, number of GPUs, and price per hour. The challenge consists in determining which instance is better for a specific deep learning problem. This paper presents the implications, in terms of runtime and cost, of running two different deep learning problems on AWS GPU-based instances, and it proposes a methodology, based on the previous study cases, that analyzes instances for deep learning algorithms by using the information provided by the Keras framework. Our experimental results indicate that, despite having a higher price per hour, the instances that contain the NVIDIA V100 GPUs (p3) are faster and usually less expensive to use than the instances that contain the NVIDIA K80 GPUs (p2) for the problems we analyzed. Also, the results indicate that the performance of both applications did not scale well with the number of GPUs and that increasing the batch size to improve scalability may affect the final model accuracy. Finally, the proposed methodology provides accurate cost and estimated runtime for the tested applications on different AWS instances with a small cost.","PeriodicalId":261870,"journal":{"name":"Proceedings of the 12th IEEE/ACM International Conference on Utility and Cloud Computing","volume":"18 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":"128850638","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 flood of provided information leads to bottlenecks within regular client-server architectures. In order to address this challenge and to enable new applications, fog computing is a promising architectural style which pushes the data and device handling closer to the edge. Thus, systems are getting more decentralized and -- with the inclusion of devices with constantly changing positions such as cars, drones and smartphones -- more dynamic. To address the corresponding challenges, we defined four concepts for dynamic Fog Architectures: Fog Visibility, Fog Horizon, Fog Reachability, and finally, a redefinition of the Fog Architecture, based on the previous concepts. These concepts support a common understanding of the constantly changing sets of components these fog environments have to deal with. In addition to the common understanding, the concepts are also helpful to set up architectures, discover communication partners as well as setting scopes. We provide mathematical definitions for each concept and give examples. In the case study, we applied these concepts in four applications from different domains to show the applicability and generalizability.","PeriodicalId":261870,"journal":{"name":"Proceedings of the 12th IEEE/ACM International Conference on Utility and Cloud Computing","volume":"42 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":"131239778","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}

Centralized approaches to improve the credibility of information do not easily scale, require trusting the service provider and have higher network delay. Blockchain solutions are promising in the area but they need consensus on the credibility of new information, which requires the participants solve computational puzzles in a competitive manner. To cope with vehicles' limited computational resources and mobility, we propose brokerage mechanism to decide whether to execute the validation locally, or to offload it to an edge or cloud infrastructure. We define a Satisfiability Modulo Theories (SMT) method to enable participants to decide whether to take part in the validation and whether to offload it considering the state of the infrastructure, energy efficiency, the offloading cost and the computation reward. Our method obtains 77.7% higher profit and consumes 39.2% less energy in comparison with the case where no offloading is allowed.","PeriodicalId":261870,"journal":{"name":"Proceedings of the 12th IEEE/ACM International Conference on Utility and Cloud Computing","volume":"36 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":"116081987","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}

Existing approaches to energy-efficient workflow scheduling in cloud computing environments have primarily focused on the optimization of server utilization. The majority of works have ignored the impact of scheduling decisions on the data center network (DCN). However, studies have revealed that the DCN consumes 10-20% of the total data center power, and this percentage could rise much higher depending on the utilization level of the data center. This paper proposes an energy-efficient workflow scheduling approach (J-OPT) that jointly optimizes the power consumption of servers and networking elements in cloud data centers. J-OPT considers precedence constraints and data dependencies among workflow tasks as well as communication requirements among task instances in the formulation of topology-aware scheduling decisions. The proposed approach is evaluated using synthetic and real world workflow traces in a simulated environment. Results of the experiments demonstrate that J-OPT outperforms state-of-the-art algorithms in terms of total power savings by 8% and 30% under high and low data center utilization levels, respectively.","PeriodicalId":261870,"journal":{"name":"Proceedings of the 12th IEEE/ACM International Conference on Utility and Cloud Computing","volume":"34 3 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":"127672204","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}

As such, research and design of such systems have proven to be challenging. Despite the influx in IoT research and the significant benefits of simulation-based approaches in supporting research, there is a general lack of appropriate modelling and simulation platforms to create a detailed representation of end-to-end IoT services, i.e. from the underlying IoT nodes to the application layer in the cloud along with the underlying networking infrastructure. To aid researchers and practitioners in overcoming these challenges, we propose IoTNetSim, a novel self-contained extendable platform for modelling and simulation of end-to-end IoT services. The platform supports modelling heterogeneous IoT nodes (sensors, actuators, gateways, etc.) with their fine-grained details (mobility, energy profile, etc.), as well as different models of application logic and network connectivity. The proposed work is distinct from the current literature, being an all-in-one tool for end-to-end IoT services with a multi-layered architecture that allows modelling IoT systems with different structures. We experimentally validate and evaluate our IoTNetSim implementation using two very large-scale real-world cases from the natural environment and disaster monitoring IoT domains.","PeriodicalId":261870,"journal":{"name":"Proceedings of the 12th IEEE/ACM International Conference on Utility and Cloud Computing","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122741428","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}
