Texto completoAlthough the accelerators market is dominated by heterogeneous MultiProcessor Systems-on-Chip (MPSoC), i.e. with different specialized processors, a growing interest is put on another type of MPSoC, composed by an array of identical processors. Even if these processors achieved lower performance to power ratio, the better flexibility and programmability of these homogeneous MPSoC allow an easier adaptation to the load, and offer a wider space of configurations. In this context, this thesis exposes the development of a scalable homogeneous MPSoC – i.e. with linear performance scaling – and different kind of adaptive mechanisms and programming model on it.This architecture is based on an array of MicroBlaze-like processors, each having its own memory, and connected through a 2D NoC. A modular RTOS was build on top of it. Thanks to a complex communication stack, different adaptive mechanisms were made: a “redirected data” task migration mechanism, reducing the impact of the migration mechanism for data-flow applications, and a “remote execution” mechanism. Instead of migrate the instruction code from a memory to another, this last consists in only migrate the execution, keeping the code in its initial memory. The different experiments shows faster reactivity but lower performance of this mechanism compared to migration.This development naturally led to the creation of a shared memory programming model. To achieve this, a scalable hardware/software memory consistency and cache coherency mechanism has been made, through the PThread library development. Experiments show the advantage of using NoC based homogeneous MPSoC with a brand programming model
Zhao, Hui. "High performance cache-aided downlink systems : novel algorithms and analysis". Electronic Thesis or Diss., Sorbonne université, 2022. http://www.theses.fr/2022SORUS366.
Texto completoThe thesis first addresses the worst-user bottleneck of wireless coded caching, which is known to severely diminish cache-aided multicasting gains. We present a novel scheme, called aggregated coded caching, which can fully recover the coded caching gains by capitalizing on the shared side information brought about by the effectively unavoidable file-size constraint. The thesis then transitions to scenarios with transmitters with multi-antenna arrays. In particular, we now consider the multi-antenna cache-aided multi-user scenario, where the multi-antenna transmitter delivers coded caching streams, thus being able to serve multiple users at a time, with a reduced radio frequency (RF) chains. By doing so, coded caching can assist a simple analog beamformer (only a single RF chain), thus incurring considerable power and hardware savings. Finally, after removing the RF-chain limitation, the thesis studies the performance of the vector coded caching technique, and reveals that this technique can achieve, under several realistic assumptions, a multiplicative sum-rate boost over the optimized cacheless multi-antenna counterpart. In particular, for a given downlink MIMO system already optimized to exploit both multiplexing and beamforming gains, our analysis answers a simple question: What is the multiplicative throughput boost obtained from introducing reasonably-sized receiver-side caches?

Texto completo5G is envisioned to tackle, in addition to a considerable increase in traffic volume, the task of connecting billions of devices with heterogeneous service requirements. In order to address the challenges of 5G, we advocate a more efficient use of the available information, with more service and user awareness, and an expansion of the RAN intelligence. In particular, we focus on two key enablers of 5G, namely massive MIMO and proactive caching. In the third chapter, we focus on addressing the bottleneck of CSI acquisition in TDD Massive MIMO. In order to do so, we propose novel spatial grouping schemes such that, in each group, maximum coverage of the signal’s spatial basis with minimum overlapping between user spatial signatures is achieved. The latter enables to increase connection density while improving spectral efficiency. TDD Massive MIMO is also the focus of the fourth chapter. Therein, based on the different rates of wireless channels aging, CSI estimation periodicity is exploited as an additional DoF. We do so by proposing a dynamic adaptation of the TDD frame based on the heterogeneous channels coherence times. The Massive MIMO BSs are enabled to learn the best uplink training policy for long periods. Since channel changes result primarily from device mobility, location awareness is also included in the learning process. The resulting planning problem was modeled as a two-time scale POMDP and efficient low complexity algorithms were provided to solve it. The fifth chapter focuses on proactive caching. We focus on improving the energy efficiency of cache-enabled networks by exploiting the correlation in traffic patterns in addition to the spatial repartition of requests. We propose a framework that strikes the optimal trade-off between complexity and truthfulness in user behavior modeling through adaptive content popularity-based clustering. It also simplifies the problem of content placement, which results in a rapidly adaptable and energy efficient content allocation framework

Texto completoGiannakas, Theodoros. "Joint modeling and optimization of caching and recommendation systems". Electronic Thesis or Diss., Sorbonne université, 2020. http://www.theses.fr/2020SORUS317.
Texto completoCaching content closer to the users has been proposed as a win-win scenario in order to offer better rates to the users while saving costs from the operators. Nonetheless, caching can be successful if the cached files manage to attract a lot of requests. To this end, we take advantage of the fact that the internet is becoming more entertainment oriented and propose to bind recommendation systems and caching in order to increase the hit rate. We model a user who requests multiple contents from a network which is equipped with a cache. We propose a modeling framework for such a user which is based on Markov chains and depart from the IRM. We delve into different versions of the problem and derive optimal and suboptimal solutions according to the case we examine. Finally we examine the variation of the Recommendation aware caching problem and propose practical algorithms that come with performance guarantees. For the former, the results indicate that there are high gains for the operators and that myopic schemes without a vision, are heavily suboptimal. While for the latter, we conclude that the caching decisions can significantly improve when taking into consideration the underlying recommendations
Tsigkari, Dimitra. "Algorithms and Cooperation Models in Caching and Recommendation Systems". Electronic Thesis or Diss., Sorbonne université, 2022. http://www.theses.fr/2022SORUS210.
Texto completoIn the context of on-demand video streaming services, both the caching allocation and the recommendation policy have an impact on the user satisfaction, and financial implications for the Content Provider (CP) and the Content Delivery Network (CDN). Although caching and recommendations are traditionally decided independently of each other, the idea of co-designing these decisions can lead to lower delivery costs and to less traffic at the backbone Internet. This thesis follows this direction of exploiting the interplay of caching and recommendations in the setting of streaming services. It approaches the subject through the perspective of the users, and then from a network-economical point of view. First, we study the problem of jointly optimizing caching and recommendations with the goal of maximizing the overall experience of the users. This joint optimization is possible for CPs that simultaneously act as CDN owners in today’s or future architectures. Although we show that this problem is NP-hard, through a careful analysis, we provide the first approximation algorithm for the joint problem. We then study the case where recommendations and caching are decided by two separate entities (the CP and the CDN, respectively) who want to maximize their individual profits. Based on tools from game theory and optimization theory, we propose a novel cooperation mechanism between the two entities on the grounds of recommendations. This cooperation allows them to design a cache-friendly recommendation policy that ensures a fair split of the resulting gains

Texto completoToday, there is a real need to strengthen the communication security to anticipate the development of quantum computing and the eventual attacks arising from it. This work explores two complementary techniques that provide confidentiality to data transmitted over wireless networks. In the first part, we focus on lattice-based public-key cryptography, which is one of the most promising techniques for the post-quantum cryptography systems. In particular, we focus on the Goldreich-Goldwasser-Halevi (GGH) cryptosystem, for which we propose a new scheme using GLD lattices. In the second part of this work, we study the security of multi-user cache-aided wiretap broadcast channels (BCs) against an external eavesdropper under two secrecy constraints: individual secrecy constraint and joint secrecy constraint. We compute upper and lower bounds on secure capacity-memory tradeoff considering different cache distributions. To obtain the lower bound, we propose different coding schemes that combine wiretap coding, superposition coding and piggyback coding. We prove that allocation of the cache memory to the weaker receivers is the most beneficial cache distribution scenario

Texto completoDefining the concepts of "work" and "job", we observed the importance of "information system " in the reinvention of "work".Noting the loss and modification of „jobs“ ; evidenced by layoffs and reorganization of enterprises , the work does not disappear , however, and invites new forms , such as statutes of freelance and student , but also by positioning the consumer as a worker.Work visible, in the form of wage labor, to work "hidden" , it is the whole society that is reinvented, and calls for new social perspectives.Through the study of two IT compagnies, for a period of 5 years , we are interested in various forms of work activity concerning 152 computer engineers .Understand the context of IT compagnies as a laboratory for modern forms of development work has enabled us to identify these updates in innovative work and valuations.The information system is forming as the undisputed center of this change of work, allows the establishment of normalized and standardized work , draws the new border of work, and open to new rewarding social and economic opportunities.If the information system contributes to the implementation of these new forms of work , managerial decisions are to be at the origin of this use.To what paradigm directs us, this use of information system?
Ben, Ammar Hamza. "On models for performance evaluation and cache resources placement in multi-cache networks". Thesis, Rennes 1, 2019. http://www.theses.fr/2019REN1S006/document.
Texto completoIn the last few years, Content Providers (CPs) have experienced a high increase in requests for video contents and rich media services. In view of the network scaling limitations and beyond Content Delivery Networks (CDNs), Internet Service Providers (ISPs) are developing their own caching systems in order to improve the network performance. These factors explain the enthusiasm around the Content-Centric Networking (CCN) concept and its in-network caching feature. The analytical quantification of caching performance is, however, not sufficiently explored in the literature. Moreover, setting up an efficient caching system within a network infrastructure is very complex and remains an open problem. To address these issues, we provide first in this thesis a fairly generic and accurate model of caching nodes named MACS (Markov chain-based Approximation of Caching Systems) that can be adapted very easily to represent different caching schemes and which can be used to compute different performance metrics of multi-cache networks. We tackled after that the problem of cache resources allocation in cache-enabled networks. By means of our analytical tool MACS, we present an approach that solves the trade-off between different performance metrics using multi-objective optimization and we propose an adaptation of the metaheuristic GRASP to solve the optimization problem
