Probabilistic dropping in push and pull dissemination over distributed hash tables
Carlini E., Coppola M, Ricci L.
Dynamic information management via Distributed Hash Tables (DHT) is an important problem which revolves around the trade-off between data freshness and the overhead due to information updates. We propose two different algorithms based on information pull and information push models, that enable dynamic information dissemination with low overhead over a DHT. We exploit the concept of popularity of specific items, which is evaluated by performing a real-time analysis of the query distribution, and allows to decrease a significant fraction of messages without impairing the query resolution process. We have measured the overhead savings and compared the performance of the two approaches by extensive simulations using real workload traces.Source: The 11th IEEE International Conference on Computer and Information Technology, CIT 2011, pp. 47–52, Pafos, Cyprus, 31 August - 2 September 2011

Reducing Server Load in MMOG via P2P Gossip.
Carlini E., Ricci L., Coppola M.
A fundamental problem for the development of Massively Multiplayer Online Games (MMOGs) is the definition of a mechanism supporting interest management, i.e. determining all the entities of the virtual world that are relevant for a given peer. To this end, we propose a hybrid architecture combining centralized and P2P solutions. Our proposal exploits a P2P gossip-based approach supporting a best-effort resolution of interest management, so that it can be mostly supported through the P2P overlay, with minimal intervention of a centralized entity.Source: The 11th Annual Workshop on Network and Systems Support for Games, pp. 2–2, Venezia, Italy, 22-23 November 2012

Flexible load distribution for hybrid distributed virtual environments
Carlini E., Ricci L., Coppola M.
This paper proposes an architecture for Distributed Virtual Environment (DVE) integrating cloud and peer nodes. We define the overall structure of the architecture and propose a flexible strategy to distribute the load due to the management of the entities of the DVE. The proposed approach takes into account the utilization of the nodes, the economical cost due to their use of bandwidth, and their probability failure. A greedy heuristics is exploited to reduce the computational cost of the algorithm in order to maintain a fair interactivity level to the end user of the DVE. A mobility model generating realistic Second Life traces is exploited to evaluate our algorithm. The experimental results show the effectiveness of our approach.Source: Future generation computer systems 29 (2013): 1561–1572. doi:10.1016/j.future.2012.09.004

Toward community-driven interest management for distributed virtual environment
Carlini E., Dazzi P., Mordacchini M., Ricci L.
A fundamental requirement for the discovery and the re- trieval of the entities of a distributed virtual environment is the definition of a scalable Interest Management (IM) support. This paper presents a distributed protocol for IM that integrates two different gossip protocols. The first one based on a discrete tessellation of the Area of Interest of a peer in order to maximise its coverage by the peer neighbours. The second is based on a distributed algorithm enabling the peers to self-organise themselves in communities. The paper presents a set of experimental results showing the effectiveness of the proposed approach.Source: Euro-Par 2013: Parallel Processing Workshops, edited by Dieter an Mey, Michael Alexander, Paolo Bientinesi (et al...), pp. 363–373, 2014

Community discovery for interest management in DVEs: A case study
Carlini E., Dazzi P., Mordacchini M., Lulli A., Ricci L.
An efficient interest management is a fundamental requirement to support Distributed Virtual Environments (DVEs). As avatars move across the virtual environment, they often forming communities by gathering around hotspots. Distributed community discovery is a research area that gained momentum in the last years. In this paper we propose a case study evaluation on the impact of communities and community discovery on a distributed gossip-based interest management architecture for DVEs. Our experimental evaluation shows that communities have a positive impacts on interest management, at the expense of a small computational and communication overheadSource: Euro-Par 2015 International Workshops, pp. 273–285, 2015

A multi-layer framework for graph processing via overlay composition
Lulli A., Dazzi P., Ricci L., Carlini E.
The processing of graph in a parallel and distributed fashion is a constantly rising trend, due to the size of the today's graphs. This paper proposes a multi-layer graph overlay approach to support the orchestration of distributed, vertex-centric computations targeting large graphs. Our approach takes inspiration from the overlay networks, a widely exploited approach for information dissemination, aggregation and computing orchestration in massively distributed systems. We propose Telos, an environment supporting the definition of multi-layer graph overlays which provides each vertex with a layered, vertex-centric, view of the graph. Telos is defined on the top of Apache Spark and has been evaluated by considering two well-known graph problems. We present a set of experimental results showing the effectiveness of our approach.Source: Euro-Par 2015: Parallel Processing Workshops, pp. 515–527, 2015

An holistic approach for high-level programming of next-generation data-intensive applications targeting distributed heterogeneous computing environment
Carlini E., Dazzi P., Mordacchini M.
Data-intensive applications are one of the largest customers of high throughput computing environments. As clearly shown by the BigData raise, there is a widely recognised urge for processing large amount of data, universallyconsidered the "new oil", from which to extract wisdom, knowledge and, more in general, information of very different kinds, ranging from commercial to financial, from medical to political hints. This extreme intrinsic richness andheterogeneity of data is paired with the extreme complexity in its storing and processing.Source: Cf 2016 - Cloud Forward Conference, pp. 131–134, Madrid, Spain, 18-20/10/2016

Challenges to be addressed for realising an ephemeral cloud federation
Carlini E., Coppola M., Dazzi P., Mordacchini M.
This paper sketches the challenges to address to realise a support able to achieve an Ephemeral Cloud Federation, an innovative cloud computing paradigm that enables the exploitation of a dynamic, personalised and context-aware set of resources. The aim of the Ephemeral Federation is to answer to the need of combining private data-centres with both federation of cloud providers and the resource on the edge of the network. The goal of the Ephemeral Federation is to deliver a context-aware and personalised federations of computational, data and network resources, able to manage their heterogeneity in a highly distributed deployment, which can dynamically bring data and computation close to the final user.Source: ISTI Technical reports, 2016

Static and dynamic big data partitioning on apache spark
Bertolucci M., Carlini E., Dazzi P., Lulli A., Ricci L.
Many of today's large datasets are organized as a graph. Due to their size it is often infeasible to process these graphs using a single machine. Therefore, many software frameworks and tools have been proposed to process graph on top of distributed infrastructures. This software is often bundled with generic data decomposition strategies that are not optimised for specific algorithms. In this paper we study how a specific data partitioning strategy affects the performances of graph algorithms executing on Apache Spark. To this end, we implemented different graph algorithms and we compared their performances using a naive partitioning solution against more elaborate strategies, both static and dynamic.Source: International Conference on Parallel Computing, pp. 489–498, Edinburgh, Scotland, 1-4 September 2015

Dynamic resource selection in cloud service broker
Santoso G. Z., Jung Y. -W., Seok S. -W., Carlini E., Dazzi P., Altmann J., Violos J., Marshall J.
Cloud Service Broker federates multiple Cloud Service Providers into a single entity to customers. The benefits that can be enjoyed by Cloud Service Consumer are flexibility, ease of use, and reduced cost. However, because of the unique properties and configurations of each cloud provider, sometime it's not easy to migrate between one cloud provider to another. Furthermore, the advantage of using broker should be obtained by consumers in any life cycle of consumer's software not only during the deployment of the software. This paper outlines the main idea and design of the dynamic resource selection in BASMATI Cloud Federation.Source: HPCS 2017 - International Conference on High Performance Computing & Simulation, pp. 233–235, Genoa, Italy, 17-21 July 2017
