LudoGraph: A Sampling Capable Cloud-Based System for Large-Scale Graph Processing: Based on the Pregel programming model

Project Jackal Final Report

For companies that deliver hardware services, the ability to scale dynamically has many advantages. In a special case, a company may have some computing resources available and desire to scale out when traffic peaks. A periodical budget may then be allocated, which needs to be used efficiently. This can be achieved through a combination of...

Hardware acceleration of simulations of distributed systems

In recent years the study of complex systems gained prominence. Since it is usually difficult to use classical mathematic models to understand these systems, scientists and engineers have to resort to simulations. Currently programming languages like CUDA C and OpenCL are available to run large scale simulations on a GPU architecture....

Musubi: Middleware for Secure Mobile Collaborative Applications

As we work more and more while on the go, mobile collaborative applications will play an increasingly important role in our lives. We note that the conventional client/server model for these applications poses several shortcomings. The model is unintuitive and unnecessarily complex. Centralized servers further introduce cost, inflexibility, and...

A workload model for MapReduce

MapReduce is a parallel programming model used by Cloud service providers for data mining. To be able to enhance existing and to develop new MapReduce sys- tems, we need to evaluate the performance of these systems. To this end we intro- duce in this work the Cloud Workloads Archive Toolbox. This toolbox facilitates the analysis of MapReduce...

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...

WebHack: A research system for social massive multiplayer online games

The Design & Implementation of a Facebook-based Interactive MMOG

The main question we seek to answer in this thesis is whether it is possible to create a fast paced MMOG for Facebook that can host hundreds of concurrent players. The main question is split in the following sub-questions: In order to answer this question, some sub-questions have been formed which focus on the performance of the system: 1. What...

Trace-based performance analysis of scheduling bags of tasks in grids

Grid computing promises large scale computing facilities based on distributed systems. Much research has been done on the subject of increasing the performance of grids. We believe that an adequate performance analysis of grids requires knowledge of the workload and the architecture of the grid. Currently, researchers assume that grids are...
