Parallel and Distributed Simulation (PADS) Research Group

University of Bologna. Department of Computer Science and Engineering (DISI)

Welcome to the PADS homepage, you can find some information about this research group, the active projects and the related publications.

A lot of our research work is based on a new Parallel and Distributed Simulation (PADS) middleware (ARTÌS). The GAIA framework provides a migration-based approach to the simulation. The ARTÌS middleware and the GAIA framework are available for educational and research purposes.

Please feel free to contact us for any question or comment.

NEW PAPER: Adaptive Parallel and Distributed Simulation of Complex Networks

In this paper we present a study on the intricate problem of the simulation of large scale complex networks. The complexity of the simulation is due to the need to represent networks with a high number of nodes and links, but even more to the need to model interactions among network nodes. We focus on discrete-event simulation, a simulation methodology that enables both sequential (i.e. monolithic) and parallel/distributed simulation (i.e. PADS) approaches.

SOFTWARE: LUNES-Blockchain preview

A preview version of the LUNES-Blockchain simulator (i.e. agent-based simulation of DLTs and Blockchains) has been published in form of source code in the Download section. LUNES-Blockchain is based on the ARTÌS/GAIA simulators.

NEW PAPER: Internet-based Adaptive Distributed Simulation of Mobile Ad-hoc Networks

In this paper we focus on Internet-based simulation, a form of distributed simulation in which a set of execution units that are physically located around the globe work together to run a simulation model. We simulate a wireless model over a real Internet-based distributed simulation setup, and evaluate the scalability of the simulator with and without the use of adaptive strategies for both communication overhead reduction and load-balancing enhancement.

NEW PAPER: Agent-based Simulation of Blockchains

In this paper, we describe LUNES-Blockchain, an agent-based simulator of blockchains that is able to exploit Parallel and Distributed Simulation (PADS) techniques to offer a high level of scalability.

NEW PAPER: Parallel Data Distribution Management on Shared-Memory Multiprocessors

In this paper we propose two parallel solutions to the DDM problem that can operate effectively on shared-memory multiprocessors.

NEW PAPER: Parallel Sort-Based Matching for Data Distribution Management on Shared-Memory Multiprocessors

In this paper, we propose a parallel version of the Sort-Based Matching algorithm for shared-memory multiprocessors.

Best Paper Award: 21-th ACM/IEEE International Symposium on Distributed Simulation and Real Time Applications (DS-RT 2017).

HPCS 2016 Tutorial

In the tutorial “Simulation of the Internet of Things”, we aim to introduce all the basic aspects of the efficient simulation of the Internet of Things (IoT).

We discuss the main limitations of the current approaches with the goal to foster discussion and to increase the knowledge on both simulation and IoT. The last part of the tutorial will be about our practical experience in the simulation of IoT using a multi-level modelling approach.

For more information follow this link and see our tutorial paper: Simulation of the Internet of Things.
