Hermes: Enabling efficient large-scale simulation in MATSim

Efficient Simulation of Large-Scale Loss Networks

Recently Rajasekaran and Ross [1] presented an algorithm that takes an expected 0(1) time to generate a nonuniform discrete random variate. In this paper we discuss how this algorithm can be employed in the efficient simulation of large-scale telephone networks. In a simulation based upon a standard event-list approach, the generation of a new event in the systems take 0(log n) time. With this ...

Efficient simulation techniques for large-scale applications

COMPUTATIONALLY EFFICIENT OPTIMUM DESIGN OF LARGE SCALE STEEL FRAMES

Computational cost of metaheuristic based optimum design algorithms grows excessively with structure size. This results in computational inefficiency of modern metaheuristic algorithms in tackling optimum design problems of large scale structural systems. This paper attempts to provide a computationally efficient optimization tool for optimum design of large scale steel frame structures to AISC...

Integrating BDI Agents into a MATSim Simulation

MATSim is a mature and powerful traffic simulator, used for large scale traffic simulations, primarily to assess likely results of various infrastructure or road network changes. More recently there has been work to extend MATSim to allow its use in applications requiring what has been referred to as “within day replanning”. In the work described here we have coupled MATSim with a BDI (Belief D...

Coordinator-master-worker model for efficient large scale network simulation

In this work, we propose a coordinator-master-worker (CMW) model for medium to extra-large scale network simulation. The model supports distributed and parallel simulation for a heterogeneous computing node architecture with both multicore CPUs and GPUs. The model aims at maximizing the hardware usage rate while reducing the overall management overhead. In the CMW model, the coordinator is the ...
