Decentral market: self-regulating electronic market

A decentral electronic marketplace to trade digital currencies was created for this project. Users may trade MultiChain balance for Bitcoin. MultiChain can be described as up- and download currency in a peer-to-peer network. When a peer uploads, the balance of that peer increases and the peer can download more effectively. The client for this...

Domain Specific Instruction Set Extensions

Over the past years, a considerable amount of effort has been devoted to the definition and implementation of techniques for the optimization and acceleration of applications on various computing platforms. Among these techniques, the extension of a given instruction-set architecture with custom instructions has become a common approach. Custom...

An empirical study of large-scale graph processing with Pregel

In this age of information, data gathering has become a new growing trend. Social networking sites, Internet banking, online communities, all gather and store data concerning their users preferences, interactions or activities. This data is strongly relational and can be represented in the form of graphs where a Vertex represents the subject of...

Performance Evaluation of Cloud Infrastructure using Complex Workloads

Infrastructure as a Service (IaaS) is a delivery model of cloud computing, which provides the ability to users to acquire and release resources according to their demand and pay according to their usage. Resources are provisioned from the cloud as Virtual Machines (VMs), many of which can be deployed on a single computing node, realizing a multi...

Tribler-G: A Decentralized Social Network for Playing Chess Online

There are currently many systems that offer online board games, for instance, social networking sites, where board games enjoy enormous popularity, but also systems such as the Internet Chess Club, which has been around for over a decade. However, these systems are all centralized and typically have drawbacks for the user, such as subscription...

Programmability Analysis of Image Processing Kernels on Multi-/Many-core Platforms

In the last few years, the computing industry has changed its course from ever higher clock speeds to multi- and many-core systems. These new parallel systems su?er a “programmability gap”: there is a large gap between the performance a platform is theoretically capable of, and what the programmer is able to achieve. Early programming models...

Adapting Particle Filter Algorithms to the GPU Architecture

The particle filter is a Bayesian estimation technique based on Monte Carlo simulations. The non-parametric nature of particle filters makes them ideal for non-linear non-Gaussian systems. This greater filtering accuracy, however, comes at the price of increased computational complexity which limits their practical use for real-time applications...

Swarm Discovery in Tribler using 2-Hop TorrentSmell

Peer-to-peer (P2P) technology allows us to create self-organising and scalable systems. The distributed nature of these systems requires a solution for finding interesting peers. In the context of P2P file sharing, finding peers who are downloading the same file is referred to as the swarm discovery problem. In BitTorrent, this problem is solved...
