Due to decelerating gains in single-core CPU performance, computationally expensive
simulations are increasingly executed on highly parallel hardware platforms. Agent-based …

Construction industry is claimed to be the fourth most dangerous sector by number of
fatalities. In complex construction sites, emergency evacuation risk assessment is a …

Cellular Automata (CA) have been introduced many decades ago as one of the most
efficient parallel computational models able to simulate various physical processes and …

OpenCAL is a scientific software library specifically developed for the simulation of 2D and
3D complex dynamical systems on parallel computational devices. It is written in C/C++ and …

Here we present a first multi-node/multi-GPU implementation of OpenCAL for grid-based
high-performance numerical simulation. OpenCL and MPI have been adopted as low-level …

This article introduces OpenCAL, a new open source computing abstraction layer for multi-
and many-core computing based on the Extended Cellular Automata general formalism …

A discretization is applied to the continuous field-based pedestrian model to derive a
discrete version. The concept of walk period is introduced so that pedestrians' varied …

A parallel algorithm is proposed for modeling of crowd multi-cell occupancy and velocity
variety. Methods are devised to solve issues such as space competitions so that each …

Agent-based model (ABM) simulation is a bottom–up approach that can describe the
phenomena generated from actions and interactions within a multiagent system. An ABM is …

Two aspects of improvements are proposed for the OpenCL-based implementation of the
social field pedestrian model. In the aspect of algorithm, a method based on the idea of …
