Numerical simulation of electrical machines by means of a hybrid parallelisation using MPI and OpenMP for FEM

In this paper, an hybrid parallelisation approach for the simulation of nonlinear electromagnetic problems by means of the Message Passing Interface (MPI) and the OpenMP Application Program Interface for the Finite Element Method (FEM) is investigated. After an introduction, the metrics applied to evaluate the speedup and the efficiency are outlined. By parallelising the institute´s in-house FEM-package “iMOOSE” either by MPI or by OpenMP, an evaluation basis for the hybrid approach is being founded. The hybrid parallelisation approach is being evaluated on the high performance computing cluster of university´s centre for computing and communication.
