AB Finite element method (FEM) has been used for years for radiation problems in thefield of electromagnetism. To tackle problems of this kind, mesh truncation techniquesare required, which may lead to the use of high computational resources.In fact, electrically large radiation problems can only be tackled using massivelyparallel computational resources. Different types of multi-core machines are commonlyemployed in diverse fields of science for accelerating a number of applications.However, properly managing their computational resources becomes a verychallenging task. On the one hand, we present a hybrid message passing interface+ OpenMP-based acceleration of a mesh truncation technique included in aFEM code for electromagnetism in a high-performance computing cluster equippedwith 140 compute nodes. Results show that we obtain about 85% of the theoreticalmaximum speedup of the machine. On the other hand, a graphics processing unithas been used to accelerate one of the parts that presents high fine-grain parallelism.
