Antitrust, Regulation and the Neutrality Trap: A Plea for a Smart, Evidence-Based Internet Policy
2015Co-Authors: Andrea RendaAbstract:EU Internet policy seems bewitched by the term 'neutrality', applied to networks and now search engines and other online platforms. Andrea Renda questions in this latest Special Report whether this is this a good way to protect end users.Originally confined to the Infrastructure Layer, today the neutrality rhetoric is being expanded to multi-sided platforms such as search engines and more generally online intermediaries. Policies for search neutrality and platform neutrality are invoked to pursue a variety of policy objectives, encompassing competition, consumer protection, privacy and media pluralism. This paper analyses this emerging debate and comes to a number of conclusions. First, mandating net neutrality at the Infrastructure Layer might have some merit, but it certainly would not make the Internet neutral. Second, since most of the objectives initially associated with network neutrality cannot be realistically achieved by such a rule, the case for network neutrality legislation would have to stand on different grounds. Third, the fact that the Internet is not neutral is mostly a good thing for end users, who benefit from intermediaries that provide them with a selection of the over-abundant information available on the Web. Fourth, search neutrality and platform neutrality are fundamentally flawed principles that contradict the economics of the Internet. Fifth, neutrality is a very poor and ineffective recipe for media pluralism, and as such should not be invoked as the basis of future media policy. All these conclusions have important consequences for the debate on the future EU policy for the Digital Single Market.

Antitrust, Regulation and the Neutrality Trap: A plea for a smart, evidence-based internet policy. CEPS Special Report No. 104/April 2015
2015Co-Authors: Andrea RendaAbstract:When they look at Internet policy, EU policymakers seem mesmerised, if not bewitched, by the word ‘neutrality’.

intel threading building block intel tbb flow graph as a software Infrastructure Layer for opencl based computations
International Workshop on OpenCL, 2016Co-Authors: Alexei Katranov, Alexey KukanovAbstract:Modern computing systems are becoming heterogeneous with a variety of programmable units: CPU, GPU, FPGA, domain-specific accelerators, etc. OpenCL™ API is a cross-platform programming model for a wide range of computing devices, but using the language in a complex heterogenous system remains a challenge. Intel® Threading Building Blocks (Intel® TBB) is a widely used C++ library for shared-memory parallel programming that provides the flow graph functionality to express unstructured parallelism and asynchronous computations. Our presentation shows how OpenCL and Intel TBB flow graph can be used in conjunction to simplify programming for complex heterogeneous systems.

IEEE MS - A Novel QoS Prediction Approach for Cloud Service Based on Bayesian Networks Model
2016 IEEE International Conference on Mobile Services (MS), 2016Co-Authors: Pengcheng Zhang, Wenrui Li, Hareton Leung, Wei SongAbstract:Considered as the next generation computing model, cloud computing plays an important role in scientific and com-mercial computing and draws wide attention from both academiaand industry. In the dynamic, complex and changeable cloudcomputing environment, Quality Of Service (QoS) is an impor-tant basis for the selection of different cloud services. Therefore, the prediction of cloud services QoS can help users to choose themost suitable service at hand. The software and hardware andresources of three-Layer structure for cloud computing will impacton cloud services QoS, but existing QoS prediction approachesare not consider the three-Layer structure on the influence of thecloud service QoS. The CPU usage, physical memory usage andthe number of processes of Infrastructure Layer have definitelyinfluenced QoS. In order to address this limitation, in the paper, a Bayesian network model of QoS prediction for cloud servicesis proposed. Firstly, an initial and basic Bayesian network modelis established by collecting data from the Infrastructure Layer, the platform Layer and the application Layer. Then the Bayesiannetwork is trained and updated to obtain the cloud service QoSprediction model. Finally, a set of experiments based on collecteddata from the real cloud service environment has been conductedto validate the proposed approach. Experimental results showthat the prediction approach is effective and accurate.

Fire Suppression and On-Site Security
Cloud Data Centers and Cost Modeling, 2020Co-Authors: Caesar Wu, Rajkumar BuyyaAbstract:This chapter consists of two main topics. One is the data center fire suppression system and the other is the on-site security system. Regarding the fire suppression issue, this chapter discusses how to select the best solution for a fire suppression system for a particular data center. One of the criteria for selection is cost considerations. The second topic is on-site or physical security systems. Based on the TIA-942 standard, different tiers of data center should have different physical security systems. The physical security system will be organized with three Layers, the physical Layer, the organizational Layer, and the Infrastructure Layer.
