The availability of high performance computing resources enables us to perform very large numerical simulations and in this way to tackle challenging real life problems. At the same time, in order to efficiently utilize the computational power at our disposal, the ever growing complexity of the computer architecture poses high demands on the algorithms and their implementation. Performing large scale high performance simulations can be done by utilizing available general libraries, writing libraries that suit particular classes of problems or developing software from scratch. Clearly, the possibilities to enhance the efficiency of the software tools in the three cases is very different, ranging from nearly impossible to full capacity. In this work we exemplify the efficiency of the three approaches on benchmark problems, using monitoring tools that provide a very rich spectrum of data on the performance of the applied codes as well as on the utilization of the supercomputer itself.
