Abstract : The capacity planning of supercomputers is a complex but important task. The best combination of hardware for the given budget has to be selected. Such choices are often guided by some common rules, elaborated after years of trial and error. The rapid development of the field, however, makes this approach costly and ineffective. We believe that experts could benefit from accurate and efficient simulators to design the next generations of supercomputers. In this work, we simulate a complex MPI application at the scale of the current top500 supercomputers, using the Simgrid simulation toolkit. We present the optimization developed to enable this kind of large scale executions, we demonstrate the soundness of the resulting simulation and we illustrate the new possibilities of study.
