The dissertation thesis presents the main results achieved within the author's research in the field of computer simulation of fires realized on high performance computers using Fire Dynamics Simulator (FDS). Analysis of the FDS applicability on modelling of fire course and consequences in selected structures (cinema hall and road tunnel) and modelling of evacuation during road tunnel fire confirmed that FDS is able to model realistically the course of fire and specific phenomena related to the fire. Study of the impact of fire on people evacuation, their movement, behaviour and escape strategies as well as analysis of the impact of the turned and/or higher capacity vehicles occurrence on evacuation are also included. Parallelization of fire simulation by the parallel MPI model of FDS and the impact of parallelization on efficiency and accuracy of the calculation is investigated. A series of new shell scripts for fire simulation execution on the HPC computer cluster at the Institute of Informatics, Slovak Academy of Sciences in Bratislava (Slovakia) in which a set of basic strategies for mapping and binding of MPI processes to computing resources of the cluster were created and the impact of their use on the fire simulation efficiency was tested. The described new knowledge and experience are crucial for accurate, reliable and efficient realization of fire simulation on high performance computers. [ABSTRACT FROM AUTHOR] |
