| Popis: | Current HPC clusters are capable to reduce execution time of parallelized tasks significantly. The paper discusses the use of two selected strategies of cluster computational resources allocation and their impact on parallel efficiency of fire simulation. Simulation of a simple corridor fire scenario by Fire Dynamics Simulator parallelized by the MPI programming model is tested on the HPC cluster at the Institute of Informatics of Slovak Academy of Sciences in Bratislava (Slovakia). The tests confirm that parallelization has a great potential to reduce execution times achieving promising values of parallel efficiency of the simulation, however, the results also show that the use of increasing numbers of computational meshes resulting in increasing numbers of used computational cores does not necessarily decrease the execution time nor the parallel efficiency of simulation. The results obtained indicate that the simulation achieves different values of the execution time and the parallel efficiency in regard of the used strategy for cluster computational resources allocation. |
