Desktop Grid is among the success stories during last years by using volunteers nodes participating into projects. Now, with the emergence of Cloud Computing, the questions become where to take resources? and how to coordinate the resources? Our assumption is that Desktop Grid will continue to survive if we are able to transform the old-fashioned client/server architecture to new web oriented architecture...
Grid and P2P systems have achieved a notable success in the domain of scientific and engineering applications, which commonly demand considerable amounts of computational resources. However, Grid and P2P systems remain still difficult to be used by the domain scientists and engineers due to the inherent complexity of the corresponding middleware and the lack of adequate documentation. In this paper...
This paper describes performance comparison of load balancing control through code migration in distributed desktop computing grids. A prototype of the middleware which migrates object code for computing is implemented, and the trade-off of code migration was observed. Based on the prototype experiment, several algorithms for location policy in desktop computing grids were examined on simulations,...
As an emergence technology, P2P is spreading to distributed simulation area, and many distributed simulation frameworks have used P2P as the middleware to interconnect their existing single processor's simulators to form distributed environments for simulation execution. In terms of simulation time management, most existing tools use a middleware layer to implement and support time management in a...
BitTorrent is probably the most popular file sharing protocol nowadays. Since it is a complex protocol which was created mostly as an engineering effort, there have been attempts to evaluate and understand the behavior of BitTorrent, exposing drawbacks and identifying opportunities for improvement. Simulation(al) and experimental evaluation are two important methodologies for the investigation of...
