Texto completo da fonteFollowing the Internet of Things (IoT) concept, each manufactured object is associated with an RFID tag (Radio Frequency IDentification) embedding a unique identifier. The incoming of this RFID in the management of goods process rises technical issues such as their integration into the Internet allowing to access object related information gathered along its life. Indeed, with the spreading of this technology, the architecture of this IoT must be scalable and must provide an efficient way for managing these informations. In order to facilitate the development and the deployment of RFID solutions, standards have been ratified by EPCGlobal specifying interfaces for an RFID middleware: a component filtering and collecting events coming from readers (ALE), a component stocking these informations (EPCIS), a component allowing to retrieve these databases (ONS), ...We propose a distributed solution of these different components by using the distributed hash tables technology. We present a distributed ALE component that provides a way to interrogate every shared reader in the network, and a solution to query and retrieve informations from EPCIS in a efficient manner, without overloading the network. Considering the importance of the ONS system, which is to IoT what DNS is to Internet, we have explored an alternate solution to the DNS one in order to distribute this component. Our solutions offer an efficient scalability to the EPCGlobal middleware, providing a generic middleware for ubiquitous computing

Texto completo da fonteThe strong and continuous improvements in the professional printing field have led to the ubiquity of printed objects in our daily life. The flexibility introduced by the digital printing process promises to associate extensive customization with mass production. The quick growth of printing usages and technologies, illustrated by wider printer farms and faster digital presses, leads to original challenges for the computer system in charge of driving them. In this thesis, we explore new approaches inspired by the high performance computing field to speedup the graphics processing necessary to digital printing. To achieve this goal, we introduce a distributed system which provides the adequate flexibility and performance by exploiting and optimizing both processing and synchronization techniques. We present our architecture up to the subtle parts of its implementation which allows our solution to meet the specific constraints on generating streams for printing purpose. We perform a complete evaluation of our solution and provide experimental evidence of its great performance and viability

Texto completo da fonteCache coherence protocol scalability problem for parallel architecture is also a problem for on chip architecture, following the emergence of manycores architectures. There are two protocol classes : snooping and directory-based.Protocols based on snooping, which send coherence information to all caches, generate a lot of messages whose few are useful.On the other hand, directory-based protocols send messages only to caches which need them. The most obvious implementation uses a full bit vector whose size depends only on the number of cores. This bit vector represents the sharing set. To scale, a coherence protocol must produce a reasonable number of messages and limit hardware ressources used by the coherence and in particular for the sharing set.To evaluate and compare protocols and their sharing set, we first propose a method based on trace injection in a high-level cache model. This method enables a very fast architectural exploration of cache coherence protocols.We also propose a new dynamic sharing set for cache coherence protocols, which is scalable. With 64 cores, 93% of cache blocks are shared by up to 8 cores.Futhermore, knowing that the operating system looks to place communicating tasks close to each other. Our dynamic sharing set takes advantage from these two observations by using a bit vector for a subset of copies and a linked list. The bit vector corresponds to a rectangle which stores the exact sharing set. The position and shape of this rectangle evolve over application's lifetime. Several algorithms for coherent rectangle placement are proposed and evaluated. Finally, we make a comparison with sharing sets from the state of the art

Texto completo da fonteIn the first part, we study consistency in a transactional systems, and focus on reconciling scalability with strong transactional guarantees. We identify four scalability properties, and show that none of the strong consistency criteria ensure all four. We define a new scalable consistency criterion called Non-Monotonic Snapshot Isolation (NMSI), while is the first that is compatible with all four properties. We also present a practical implementation of NMSI, called Jessy, which we compare experimentally against a number of well-known criteria. We also introduce a framework for performing fair comparison among different transactional protocols. Our insight is that a large family of distributed transactional protocols have a common structure, called Deferred Update Replication (DUR). Protocols of the DUR family differ only in behaviors of few generic functions. We present a generic DUR framework, called G-DUR. We implement and compare several transactional protocols using the G-DUR framework.In the second part, we focus on ensuring consistency in non-transactional data stores. We introduce Tuba, a replicated key-value store that dynamically selects replicas in order to maximize the utility delivered to read operations according to a desired consistency defined by the application. In addition, unlike current systems, it automatically reconfigures its set of replicas while respecting application-defined constraints so that it adapts to changes in clients’ locations or request rates. Compared with a system that is statically configured, our evaluation shows that Tuba increases the reads that return strongly consistent data by 63%

Texto completo da fonteProvenance is a key metadata for assessing electronic documents trustworthiness. It allows to prove the quality and the reliability of its content. With the maturation of service oriented technologies and Cloud computing, more and more data is exchanged electronically and dematerialization becomes one of the key concepts to cost reduction and efficiency improvement. Although most of the applications exchanging and processing documents on the Web or in the Cloud become provenance aware and provide heterogeneous, decentralized and not interoperable provenance data, most of Provenance Management Systems (PMSs) are either dedicated to a specific application (workflow, database, ...) or a specific data type. Those systems were not conceived to support provenance over distributed and heterogeneous sources. This implies that end-users are faced with different provenance models and different query languages. For these reasons, modeling, collecting and querying provenance across heterogeneous distributed sources is considered today as a challenging task. This is also the case for designing scalable PMSs providing these features. In the fist part of our thesis, we focus on provenance modelling. We present a new provenance modelling approach based on semantic Web technologies. Our approach allows to import provenance data from heterogeneous sources, to enrich it semantically to obtain high level representation of provenance. It provides syntactic interoperability between those sources based on a minimal domain model (MDM), supports the construction of rich domain models what allows high level representations of provenance while keeping the semantic interoperability. Our modelling approch supports also semantic correlation between different provenance sources and allows the use of a high level semantic query language. In the second part of our thesis, we focus on the design, implementation and scalability issues of provenance management systems. Based on our modelling approach, we propose a centralized logical architecture for PMSs. Then, we present a mediator based architecture for PMSs aiming to preserve provenance sources distribution. Within this architecture, the mediator has a global vision on all provenance sources and possesses query processing and distribution capabilities. The validation of our modelling approach was performed in a document archival context within Novapost, a company offering SaaS services for documents archiving. Also, we propose a non-functional validation aiming to test the scalability of our architecture. This validation is based on two implementation of our PMS : he first uses an RDF triple store (Sesame) and the second a NoSQL DBMS coupled with the map-reduce parallel model (CouchDB). The tests we performed show the limits of Sesame in storing and querying large amounts of provenance data. However, the PMS based on CouchDB showed a good performance and a linear scalability
