SHAPE Project AXESSIM - CINES Partnership: HPC for connected Objects

AxesSim has developed an electromagnetic simulation tool named TETA, which is optimized for harnessing several GPUs in parallel. It is based on the Discontinuous Galerkin method in the Time Domain (DGTD). This method allows to handle meshes of complex geometries and can model designs with high precision such as a full human body with its organs, clothes and surrounding environment. The targeted architecture is a CRAY XC50 (PizDaint) which is a supercomputer with Intel Broadwell CPUs and NVidia P100 GPUs. Both CPU and GPU are addressed via the OpenCL library. MPI is used for communication between accelerators and hosts.
