Cloud services in the Guifi.net community network
TLDR
A framework for building a collaborative distributed community cloud system that employs resources contributed by the members of the community network for provisioning infrastructure and software services is proposed, tailored to the specific social, economic, and technical characteristics of community networks and requirements for community clouds. Expand
Clouds of small things: Provisioning infrastructure-as-a-service from within community networks
TLDR
The initial results suggest that the performance of the community clouds highly depends on the community network conditions, but has some potential for improvement with network-aware cloud services. Expand
Towards Incentive-Based Resource Assignment and Regulation in Clouds for Community Networks
TLDR
From the analysis of the community network's topology, two scenarios of community clouds are derived, the local cloud and the federated cloud, and an architecture tailored to community networks is developed which integrates the incentive mechanism. Expand
Support service for reciprocal computational resource sharing in wireless community networks
TLDR
A service to incentivize the contribution of computing and storage as cloud resources to community networks, in order to stimulate the deployment of services and applications, so that in the long term, the users of community networks will not need to consume applications from the Internet, but find them within the wireless community network. Expand
A Distributed Auctioneer for Resource Allocation in Decentralized Systems
TLDR
This paper proposes a framework of distributed simulations of the auctioneer that are Nash equilibria resilient to coalitions and asynchrony, and implements a prototype that instantiates the framework for bandwidth allocation in community networks, and evaluated it in a real distributed setting. Expand
Efficient Compute at the Edge: Optimizing Energy Aware Data Structures for Emerging Edge Hardware
TLDR
DeltaTree, a concurrent energy-efficient and locality-aware data structure based on relaxed cache-oblivious model and van Emde Boas trees, is analyzed on Intel's specialized computing platform Movidius Myriad 2, designed for machine vision and computing capabilities at the edge. Expand
Using the flexible ligand bis(2-hydroxyethyl)amino-tris (hydroxymethyl)methane ("bis-tris") to access a family of 3d-4f Mn(III)4Ln4 complexes.
TLDR
This is the first report of this versatile ligand being used to target 3d-4f CCs, and the paramagnetic metal ions within the clusters are weakly antiferromagnetically coupled. Expand
Supporting cloud deployment in the Guifi.net community network
TLDR
The long term vision is that the users of community networks will not need to consume cloud applications from the Internet, but find them within the community network. Expand
HeTM: Transactional Memory for Heterogeneous Systems
TLDR
This work introduces the abstraction of Heterogeneous Transactional Memory (HeTM), which provides programmers with the illusion of a single memory region, shared among the CPUs and the (discrete) GPU(s) of a heterogeneous system, with support for atomic transactions. Expand
On Edge Cloud Service Provision with Distributed Home Servers
TLDR
This paper argues to build a collaborative edge cloud deployed on home servers and positions the proposed system and describes its building elements, where it uses Docker containers for provisioning the services. Expand
