Abstract

Supercomputers are widely used across variety of industries. Civil Engineering methods of numerical modelling are conservative and new technologies are used only occasionally. As numerical models become more complex with more detailed material models and a more extensive construction model, the limits of standard workstations are often reached. When a large task with many unknowns and nonlinearities needs to be solved, the demands on hardware requirements are high. In such cases supercomputers are convenient because they allow to solve larger tasks then a standard workstation Low computational time is another advantage of a supercomputer. Finally, the supercomputer doesn't need a huge investment from the user, because only computing time is rented. Appropriate resource allocation is essential to maximize the computational potential of a supercomputer. The task in this article is aimed on a soil-foundation interaction. The Ansys HPC commercial software was used for the calculations on the Anselm cluster in the National Supercomputing Center IT4 Innovations in VSB-Technical University of Ostrava. The optimal method of resources allocation was observed and discussed with regard to task size and a calculation time. The article consists of two examples. First example was computed on 16 nodes with the 16 Ansys HPC licenses with various methods of recourses allocation. The second example evaluated using all available HPC licenses in the National Supercomputing Center IT4Innovations. The maximal possible task size was evaluated in all used methods.
