SHAPE Pilot ENTARES Engineering: Electromagnetic simulation for large model using HPC

We have started the extension of the electromagnetic software CAPITOLE developed at ENTARES Engineering to HPC machines. This has been possible with the aid of the SHAPE pilot project, which has provided us with some expertise and computation hours at Marenostrum III. Two numerical methods have been addressed to solve the resulting dense MoM linear system, MSCBD and MLACA. A new implementation based on asynchronous tasks has been performed for the direct method MSCBD. Dependencies between tasks need to be well defined before moving to a runtime scheduling such as STARPU. As for the iterative method MLACA, a hybrid MPI-OpenMP parallelization has been done with excellent results. So far, electromagnetic models up to 6 Million unknowns have been properly solved.
